Viet Nam officially inaugurated its first oil refinery on Feb. 22, in what is being hailed as an important event in the country's development and energy security.
Prime Minister Nguyen Tan Dung attended the inauguration ceremony and pressed the button to launch the first flow of commercial oil of the Dung Quat oil refinery that is located in the central province of Quang Ngai.
Former National Assembly Chairman Nguyen Van An, Head of the Party Central Committee’s Commission for Inspection Nguyen Van Chi, Head of the Party Central Committee’s Commission for Mass Mobilisation Ha Thi Khiet, and Deputy PM Hoang Trung Hai, Head of the state steering committee for key oil and gas projects, were present at the ceremony among others.
Party General Secretary Nong Duc Manh also sent a basket of flowers to congratulate the event.
Addressing the function, PM Dung praised concerted efforts of officials, experts, engineers, workers, project management board and contractors to overcome a wide range of difficulties and challenges during thousands of days to bring out the Dung Quat oil refinery’s first flow of petroleum – an expectation of the whole country.
This is the first commercial oil flow produced by the nation’s first oil refinery that is equipped with technology, managed and operated by Vietnam itself, he said, adding that “it marks an important start of the oil refinery and petrochemical industry.”
The government leader went on to say that the oil refinery is a milestone and a key national project of great significance in all aspects, from politics, economy, society, national defence and security to the country’s industrialisation and modernisation, for Quang Ngai province and the whole central region.
The Dung Quat oil refinery was defined by the Vietnamese National Assembly as a key national work which needs to use advanced technologies and techniques to produce high-grade products meeting strict requirements for environmental protection.
Accordingly, with the designed capacity of refining 6.5 million tonnes of crude oil a year, the refinery is expected to meet about 30 percent of local demand for petroleum.
The oil refinery construction was undertaken by the Technip contractor group that included Technip (France), Technip (Malaysia), JGC (Japan), and Tecnicas Reunidas (Spain).
During the construction process, started in 2005, the Technip group already recruited more than 100 Vietnamese sub-contractors and suppliers of related equipment and services.
It has generated jobs for tens of thousands of local people in Quang Ngai and at peak periods employed up to 12,000 workers from other localities in Vietnam and more than 30 countries around the world.
The plant is expected to run at its full capacity in this August.
When running in full, the Dung Quat oil refinery is capable of churning out about 150,000 tonnes of petrol, 240,000 tonnes of diesel, and around 23,000 tonnes of LPG a month.
Additionally, it can also be producing over 8,000 tonnes of Propylene, 30,000 tonnes of jet fuel and around 25,000 tonnes of FO.
In total, this year the plant is expected to hit the market with about 2.6 million tonnes of oil products.
To serve the full operation, the Dung Quat refinery has since May, 2008 conducted several test runs, using 1,500 tonnes of LPG, over 50,000 tonnes of diesel, and 160,000 crude oil from the Bach Ho (White Tiger) oilfield.
More than 1,000 people have been trained to operate and manage the refinery.
Also in May, 2008, the one-member Binh Son Refinery and Petrochemical Company was established in order to manage and operate the oil refinery effectively.
The same day, the Quality and Standard Directorate handed over a quality certificate to the first petroleum flow produced by the Dung Quat oil refinery.

Dung Quat Oil Refinery begins operations
On February 9th, the Dung Quat Refinery in the Central Province of Quang Ngai officially began became operational.
The crude oil distillation tower in the CDU atmospheric pressure unit, one of the most important units of the Dung Quat refinery, has started refining around 900,000 tons of crude oil, reaching 60 percent of its total processing capacity. A crew of more than 700 foreign experts and Vietnamese engineers are always on duty to ensure optimal operations of the refinery.
After the 24 hours of operation, the refinery was operating safely, without any problems. Mr Venkateban, a supervisor from the Technip Company excitedly said: “I believe that we will produce the first oil products very soon, in a few days”
The foreign experts and the Vietnamese engineers are slowly and gradually increasing the flow of petroleum into the refinery and distiling the two first commercial products, namely diesel and kerosene fuels. As scheduled, the quality of the two products will be tested in coming days before being entering the supply chain. Nguyen Hoai Giang, Vice Manager of the Project said: “The first commercial products are expected to become available by the end of this week.”
The Dung Quat Refinery also plans to produce several other distiled petroleum products such as A90, A92, A95 petrol and aviation fuel by April, 2009. The refinery will bring all 14 units into operation by the end of June, 2009.
All construction and assemble work have been completed, and after 44 months of constructing the Dung Quat Refinery Plant was finished ahead of the deadline of February 25th, 2009.
The first distil petroleum products will enter the supply chain on February 22nd, 2009.

It’s all systems go for Vietnam’s first oil refinery
With its glittering bright lights and surrounded by pine forests that whistle in the dark night, Dung Quat Oil Refinery in the central province of Quang Ngai looks like a small but beautiful city.
It is Vietnam’s first oil refinery and has a capacity of 6.5 million tons of crude oil a year initially. It hopes to increase this to 10 million tons in a few years.
SGGP spoke to the deputy director of the Vietnam Petrol and Oil Group (PetroVietnam), Truong Van Tuyen, about how the plant took shape.
Reeling off figures without referring to any notes, he said the factory began its trial run on July 25. Up to now, most technical processes have been tested thoroughly.
Around 52,500 tons of diesel have been processed during the test run and the refinery’s readiness has been estimated at 99 percent.
Tuyen agreed to let the media visit the plant but said “you should come in the evening and also visit Cay Sau hill, which will be used as a vantage point to view the factory.”
Cay Sau hill is not too high but with a seven-kilometer road still under construction, conditions very muddy and difficult. At the top of the hill flies the national flag.
From the top, the refinery looked a picture in the afternoon sunlight. We could see a crude oil tank that can contain 390,000 cubic meters (around 210,000 tons) and the actual refinery with its huge distilling towers where petrol products, LPG, and propylene are produced.
To build this giant refinery, there were sometimes 15,000 people and 500 foreign experts, working.
The engineers and workers who built it would surely do better when they work on future refinery projects, he said.
On November 30 it received its first batch of 80,000 tons of crude oil from Bach Ho (white tiger) oil field for a test run.
Tuyen said 25 days after Tet, the first Vietnamese-made petroleum products will come to the market.

BP to supply crude oil for Dung Quat refinery
The oil giant, British Petroleum, is to supply crude oil to Dung Quat, Vietnam ’s first oil refinery, in accordance with a contract signed in Hanoi on Jan 12 by the British company and Vietnam ’s PV Oil and BSR firms.
PV Oil is responsible for negotiating with BP over the purchase of crude oil, which will gradually replace the supply of crude from Vietnam ’s Bach Ho (White Tiger) oil field, whose output is expected to decrease in the future.
Dung Quat refinery, which is to commence operations on Feb 25, is designed to process 3.5 million tonnes of oil during 2009, or 70-75 barrels per day. Its annual capacity is set to increase to 6.5 million tonnes, equivalent to 100-145 barrels per day in subsequent years.
Once fully operational, the refinery will meet 30 percent of domestic demand. Vietnam currently imports 13 million tonnes of petro and oil per year.

Vietnam to have made-in-Vietnam oil and petrol products
VietNamNet Bridge – The Dung Quat Oil Refinery is expected to be putting out the first made-in-Vietnam commercial oil flow in two months, according to Deputy General Director of Dung Quat Oil Refinery Dinh Van Ngoc.
Ngoc said that the oil refinery will become officially operational on February 25, 2009. To date, 98.5% of works have been completed, allowing the oil refinery to be put into operation on schedule.
What kinds of products will be launched onto the market from the Dung Quat oil refinery?
The oil refinery has been designed to churn out nine products, including propylene, 150,000 tonnes a year. We have signed a contract with Marubeni on Japan’s consumption of the product until the construction of the polypropylene (PP) workshop at Dung Quat is finished, expected at the end of October 2010. When the workshop becomes operational, propylene will be sent to the PP workshop and made into plastic beads to serve local industries.
The other products are LPG, liquidised gas, with the capacity of 300,000 tonnes per annum, petrol of different types, A90, A92 and A95, 1.9mil tonnes, fuel for jet engines, and petrol for aircrafts (jet A1), 360,000 tonnes at maximum, diesel, 3mil tonnes per annum, and FO, 400,000 tonnes a year.
Dung Quat oil refinery is scheduled to run at 60-65% designed capacity from February to June 2009 and 70% of designed capacity from June-August. As of August 2009, it will run at 100% capacity. It is expected that in 2009, the oil refinery will consume approximately 4mil tonnes of crude oil, producing 3.6mil tonnes of products. As of 2010, it will meet 30% of the country’s demand.
Does PetroVietnam plan to expand the oil refinery?
PetroVietnam is considering upgrading the capacity of the oil refinery, and the optimal solution is to increase the capacity of the existing facilities at Dung Quat economic zone. This solution would save investment capital, requiring the fewest adjustments and the shortest time. When we have a big oil refinery, a 5% or 10% increase in capacity will be significant. We don’t have to make heavy investment in equipment, but can raise capacity and gain high economic efficiency.
The second solution is to install a second production line, taking full advantage of labour resources, peripheral support, infrastructure and deep water seaports.
Does this mean that Vietnamese people will have cheap petrol and oil products in a short time?
Dung Quat oil refinery will operate under the management of the government and PetroVietnam. Petrol and oil prices will depend on the government’s policies regarding the stabilisation of the market and sustainable development. However, I can say that the sale prices of products from Dung Quat oil refineries will be competitive and follow market laws.

Deputy PM reminds oil refinery contractors of February deadline
With major sections of the Dung Quat oil refinery almost complete, contractors should continue to work quickly to make sure of meeting its February deadline, Deputy Prime Minister Hoang Trung Hai said Saturday.
They should encourage workers to work during the Tet holidays, he said during a visit to the country’s first refinery in the central province of Quang Ngai.
The refinery management told Hai that work on major tendering packages has almost been wrapped up.
Quality inspections have been completed on tendering package 5A to build a breakwater, package 5B (oil products export jetty), and package 7 (administrative and service facilities), managers said.
EPC (engineering-procurement-construction) tendering packages 1+4 and 2+3 for procurement and installation of equipment and facilities have seen 98.4 percent of the work completed, they said.
Earlier this month the refinery received 80,000 tons of crude oil for a test run. PetroVietnam Oil Corporation (PV Oil) dispatched the oil from Bach Ho (White tiger) oil field off the Vietnamese coast.
The management said 1,046 workers have been trained to work in the refinery, which is set to hire around 1,200 in all when commissioned.
Hai urged the Electricity of Vietnam (EVN), the monopoly state power supplier, to link the refinery’s power turbines to the national grid. He also instructed the Quang Ngai Province administration to complete site clearance for the Dung Quat Economic Zone.
Safety and security first
Hai also called on agencies concerned to ensure the site’s security.
Many crimes were reported this year in the economic zone, where the refinery is located, including murders, stabbings, thefts of construction materials and drug deals. The zone, 870 kilometers from Ho Chi Minh City, also houses many other petrochemical and heavy industries.
Vietnam is Southeast Asia’s third-largest crude oil producer with output averaging 350,000 barrels per day.
But it still imports most of its oil products in the absence of a refinery.
Capitalized at US$2.5 billion, Dung Quat will have a capacity to refine 6.5 million tons of crude annually. PetroVietnam is seeking to raise that to 10 million tons.
When fully operational, Dung Quat will supply more than 40 percent of the oil needs of Vietnam, which has a population of 86.5 million and more than 20 million motorbikes.
Demand is expected to grow 13-15 percent annually.
Later Saturday Hai visited Doosan Vina Company and called on the South Korean firm to fulfill its commitments to workers and set up a labor union soon to avert future industrial action like the wildcat strike that hit the firm earlier this month.
Two weeks ago around 1,300 workers gathered in front of the company to demand proper treatment and payment of allowances.
They agreed to go back to work after the firm, which makes cranes, pressure tanks and filtering devices, promised it would soon set up a labor union, improve the quality of food, guarantee safety, and behave better with employees.

Countdown for first oil refinery
More than 10,000 engineers and workers on the construction site of the Dung Quat Oil Refinery are hard at work for the first flow of commercial petrol products in two months’ time.
Visitors to the Dung Quat Economic Zone in the central province of Quang Ngai during these days are filled with pride at the sight of a modern oil refinery – the first of its kind in Vietnam – taking shape.
The refinery has just received 80,000 tonnes of crude oil from Bach Ho (White Tiger) oilfield and imported more than 52,000 tonnes of diesel oil for a test run.
The plant is in its final stage, with 98 percent of the work completed. Several components such as boilers and cooling towers are undergoing a trial period. Engineers are also testing the oil pipeline system, which is thousands of metres long, to ensure its safety.
Currently, more than 100 domestic and international contractors and more than 10,000 engineers and workers are working on the site. About 300 Vietnamese engineers are testing control equipment and accessories together with international contractors in the hope that all the equipment will be ready for use when the refinery is up and running.
The project management unit is putting the final touches on a floating port for petroleum export and a power generator, and will import liquefied gas to run the refinery.
The refinery is scheduled to churn out the first flow of commercial petrol products on February 25. Its major products are diesel, petrol, kerosene, aircraft fuel and liquefied petroleum gas (LPG). With a design capacity of 6.5 million tonnes a year, it is expected to meet one third of the country’s fuel demand.

Vietnam’s first refinery gets crude for test run
The Dung Quat oil refinery in central Quang Ngai province on Nov. 30 received the first 80,000 MT of crude oil that will service its test-runs.
Present at the event, Vice Chairman of the National Assembly Huynh Ngoc Son expressed his belief that the Vietnam Oil and Gas Group, the Dung Quat oil refinery project management board and relevant sectors will work to put the refinery into operation on schedule to ensure energy security for the country.
According to the Vietnam Oil and Gas Group’s plan, the Dung Quat oil refinery will get 4 million tonnes of crude oil from the Bach Ho (White Tiger) oil field for its one-year test-running period.
The supply of crude oil will be undertaken by the Oil Corporation (PV Oil), which will take the responsibility of distributing all 3.4 million tonnes of oil and gas products produced by the Dung Quat oil refinery.
When officially operating in 2010, the Dung Quat oil refinery is expected to churn out around 5.7 million tonnes of petrol and oil of international standard to primarily serve domestic consumption.
The country’s first refinery is designed to be capable of refining 6.5 million tonnes of crude oil into LPG, Propylene and petrol 90RON, 92RON, kerosene, Jet A1, diesel, FO which are expected to meet around 30 percent of local demands.
So far, the Dung Quat refinery has almost 98 percent of its construction workload completed. It is expected to start commercial operation by late February, 2009.
On Nov. 12, the refinery put its first generator, a 4002A turbine, of four generators that will provide electricity to power the refinery, into operation. The remaining three generators are expected to become operational by the end of December this year.

Anh Hà Chí Quân, kỹ sư công nghệ tham gia lớp học, cho biết: “Dựa trên mô hình mô phỏng, các chuyên gia nước ngoài trực tiếp hướng dẫn tỉ mỉ từng thao tác theo qui trình khởi động nhà máy cho đến khi sản phẩm đạt tiêu chuẩn; xử lý các tình huống xảy ra trong quá trình vận hành; quy trình dừng thông thường, dừng khẩn cấp như thế nào… Thao tác điều khiển sơ đồ trên màn hình trong lớp học cũng phải tuân thủ kỷ luật thép”.
Hầu hết kỹ sư tham gia khóa đào tạo đều đã trải qua các khóa đào tạo cơ bản về dầu khí, ngoại ngữ chuyên ngành, đào tạo chuyên sâu ở nước ngoài hoặc tại từng môđun ở các phân xưởng công nghệ của Dung Quất. Ông Đinh Văn Ngọc, phó trưởng ban quản lý dự án Dung Quất, nhấn mạnh: “Với khóa đào tạo, các kỹ sư sẽ vào vai với các tình huống trên sơ đồ mô hình mô phỏng trên màn hình điều khiển, phải luyện lý thuyết như “tập trận” trước khi vận hành chính thức nhà máy”.
Học xong vào cuộc ngay!

Qua sơ đồ trên màn hình điều khiển, các kỹ sư tham gia lớp học tiếp cận nhiều tình huống cụ thể: mức dầu tăng, nhiệt độ giảm, bật - tắt van máy bơm, áp suất, độ mở các van, tình trạng hoạt động các thiết bị... Trung tâm điều khiển Dung Quất được thiết kế đặc biệt chống cháy nổ, có hệ thống MIMIC cảnh báo rò rỉ khí, báo cháy tự động và điều khiển chữa cháy từ xa.
Anh Lê Trọng Khải, kỹ sư lọc - hóa dầu, cho biết: “Việc vận hành nhà máy bao gồm hai bộ phận kết nối qua bộ đàm cầm tay: kỹ sư vận hành trong trung tâm điều khiển từ xa như “thuyền trưởng”, còn người vận hành ngoài công trường như “thủy thủ”. Hai bộ phận phải phối hợp đồng bộ, chặt chẽ thì việc vận hành nhà máy mới đảm bảo an toàn, hiệu quả”.
Ông Manuel Custodio, chuyên gia đào tạo lớp học mô hình mô phỏng vận hành Nhà máy lọc dầu Dung Quất, nhận định: “Kỹ sư VN tiếp cận rất nhanh kiến thức vận hành và kỹ năng xử lý các tình huống. Tôi tin họ có thể vận hành nhà máy hiệu quả trong thời gian tới”.
Ông Đinh Văn Ngọc khẳng định: kết thúc khóa đào tạo này, ban quản lý sẽ bầu chọn những kỹ sư giỏi vào các vị trí then chốt (phân xưởng trưởng, ca trưởng, kíp trưởng…) để chỉ đạo vận hành nhà máy. Đồng thời sẽ chọn khoảng sáu kỹ sư giỏi từ khóa đào tạo để hướng dẫn lại cho gần 1.000 kỹ sư, công nhân vận hành tại các phân xưởng nhà máy.

Nguồn nhân lực cho Dung Quất
Theo dự báo của các chuyên gia kinh tế thì tới năm 2010, các dự án đầu tư tại khu kinh tế Dung Quất cần khoảng 31.000 lao động (LĐ), trong đó số LĐ qua đào tạo phải chiếm 80% - nghĩa là khoảng 25.000 người. Đó là bài toán không dễ tìm đáp số.
UBND tỉnh Quảng Ngãi đã phê duyệt phương án đào tạo cung ứng 25.000 LĐ với kinh phí trên 212 tỉ đồng, nhưng trong đó số LĐ phổ thông chiếm khoảng 18.000 người (tính chung cả LĐ gọi là "sơ cấp", vì đào tạo theo kiểu "sơ cấp" này thì chất lượng thế nào ai cũng đã biết).
Đã có một trường dạy nghề tại Dung Quất hoạt động từ mấy năm nay, nhưng chất lượng đào tạo nghề còn rất nhiều bất cập. Nhiều học sinh khi tốt nghiệp ở trường này về LĐ tại các doanh nghiệp ngay tại Dung Quất thì các doanh nghiệp phải đào tạo lại. Những hợp đồng đào tạo theo đơn đặt hàng đã có nhưng chưa nhiều và chất lượng cũng chưa đảm bảo.
Trong khi Nhà máy lọc dầu số 1 Dung Quất chỉ còn hơn 100 ngày nữa là chính thức đi vào hoạt động, thì nhu cầu công nhân kỹ thuật ở nhiều lĩnh vực phục vụ trực tiếp cho nhà máy lọc dầu, rồi các nhà máy hóa dầu đang rất "nóng", nhưng nguồn cung ứng vẫn chưa tính được một cách cụ thể. Nói cung ứng LĐ ở đây là nói tới LĐ có tay nghề, thậm chí có tay nghề ở mức khá cao, là điều mà lâu nay nước ta có quá ít trường dạy nghề có thể bảo đảm là đáp ứng đúng mức.
Câu nói "thừa thầy thiếu thợ” mà ta hay nghe lâu nay than phiền về tình trạng thừa kỹ sư mà thiếu thợ lành nghề, thực ra cũng chưa chính xác. Chúng ta đang "thừa” những kỹ sư thiếu những kỹ năng nghề nghiệp đúng mức kỹ sư, nghĩa là về mặt này, chúng ta vẫn đang thiếu.
Thực tế ở Nhà máy lọc dầu Dung Quất, ở các doanh nghiệp vận hành với kỹ thuật cao tại Dung Quất, tình trạng không chỉ thiếu công nhân lành nghề, mà còn thiếu rất nhiều kỹ sư thực sự có trình độ, có ngoại ngữ, có thể tiếp thu tốt những quy trình kỹ thuật cao mà các chuyên gia nước ngoài "trao truyền" là có thật. Và tình trạng này chưa thể khắc phục trong thời gian ngắn trước mắt, khi phương pháp đào tạo tại các trường đại học của chúng ta vẫn theo cách "thầy đọc trò chép" và chương trình học chỉ nặng về lý thuyết… suông. Học như thế thì khi ra trường bắt buộc nhà tuyển dụng phải đào tạo lại nếu tiếp nhận, làm kéo dài thời gian học một cách phí phạm.
Đã có tình trạng như ở Quảng Ngãi, khi các nhà tuyển dụng được khuyến cáo cần ưu tiên số một cho con em tỉnh nhà, đặc biệt là con em ở khu kinh tế Dung Quất, nhưng sau mỗi lần sát hạch, thì số thí sinh quê Quảng Ngãi, quê Dung Quất đã ít, mà số được nhận vào làm việc còn quá ít.
Đó là điều đau lòng cho một địa phương như Dung Quất, như Quảng Ngãi, nơi người dân đã phải hy sinh rất nhiều cho sự hình thành và phát triển của khu kinh tế, của nhà máy lọc dầu. Làm thế nào để có thể thu nhận tối đa con em ở Dung Quất, Bình Sơn, Quảng Ngãi vào làm việc, đó là câu hỏi mà một cuộc hội thảo về "Nguồn nhân lực cho Dung Quất" vừa được tổ chức ngay tại Dung Quất đã cấp thiết đặt ra. Đã có nhiều phương án nhằm giải quyết việc đào tạo nhân lực cho Dung Quất, nhưng phương án nào cũng không thể bỏ qua các trường dạy nghề.
Vấn đề bây giờ là làm thế nào nâng cấp các trường dạy nghề đã có, và hình thành thêm những trường dạy nghề mới, với chương trình đào tạo hướng theo chuẩn quốc tế, nhằm đáp ứng tốt nhất cho nhu cầu nhân lực ngay tại Dung Quất. Một khi nhà máy lọc dầu số 1 nâng công suất từ 6,5 triệu tấn/năm theo thiết kế ban đầu lên 10 hay 12 triệu tấn/năm như chủ trương của Chính phủ, thì nhu cầu nhân lực có tay nghề cao càng trở nên cấp thiết.

FOSSILS INTO FUELS: Basic Knowlegde
Fossil fuels were formed from the fossillized remains of dead plants and animals that once lived millions of years ago. Oil and natural gas are the products of the deep burial and decomposition of dead plants and animals. Heat and pressure, in the absence of oxygen, transform the decomposed material into tiny pockets of gas and crude oil. The oil and gas then migrates through the pores in the rocks to eventually collect in reservoirs.
Coal comes mainly from dead plants which have been buried and compacted beneath sediments. Most coal originated as peat in ancient swamps created many millions of years ago.
What is crude oil?
Crude oil is a complex mixture of hydrocarbons with small amounts of other chemicals such as sulphur. The crude oil is useless as a mixture and must be sent to an oil refinery to be separated. Crude oils from different parts of the world, or even from different depths in the same oilfield, contain different mixtures of hydrocarbons and other compounds. This is why they vary from light coloured volatile liquids to thick, dark oils.
What is natural gas?
Natural gas is a mixture of hydrocarbons with small molecules. These molecules are made of atoms of carbon and hydrogen. For example, natural gas used in the home is mainly methane, CH 4.
What is a hydrocarbon?
Hydrocarbons only contain hydrogen and carbon atoms. There are two main chemical families of hydrocarbons - the alkanes and the alkenes. Thousands of synthetic products can be manufactured from hydrocarbons with many different properties. Click here for some more info on polymers and plastics.
Oil Refinery: Basic Knowledge
A refinery is a factory. A refinery takes a raw material (crude oil) and transforms it into petrol and hundreds of other useful products. A typical large refinery costs billions of pounds to build and millions more to run and upgrade. It runs around the clock 365 days a year, employs hundreds of people and occupies as much land as several hundred football pitches.A REFINERY breaks crude oil down into its various components, which then are selectively changed into new products. This process takes place inside a maze of pipes and vessels. The refinery is operated from a highly automated control room.
All refineries perform three basic steps:
- Separation (fractional distillation)
- Conversion (cracking and rearranging the molecules)
- Treatment
Modern separation involves piping crude oil through hot furnaces. The resulting liquids and vapours are passed into distillation towers:
| FRACTION | B Pt oC | Number of carbons | Uses | ||||
 | »Refinery gas | 1-4 | Bottled gas, fuels | ||||
| »Petrol | 40 | ~8 | Fuel for cars | ||||
 | »Naptha | 110 | ~10 | Raw material for chemicals and plastics. | |||
 | »Kerosine | 180 | ~15 | Fuel for Aeroplanes | |||
 | »Diesel | 250 | ~20 | Fuel for cars and lorries | |||
 | »Oils | 340 | ~35 | Fuel for Power Stations, Lubricants and grease | |||
| Hot crude » |  | »Bitumen | 400+ | 40+ | Road surfacing. | ||
- It is important to realise that the column is hot at the bottom and cool at the top.
- The crude oil separates into fractions according to weight and boiling point.
- The lightest fractions, including petrol and liquid petroleum gas (LPG), vapourise and rise to the top of the tower.
- Kerosine (aviation fuel) and diesel oil, stay in the middle of the tower
- Heavier liquids separate lower down.
- The heaviest fractions with the highest boiling points settle at the very bottom.
The following table shows how the behaviour of the hydrocarbon molecules alter:
| AT THE TOP OF THE COLUMN | AT THE BOTTOM OF THE COLUMN | |
|
| |

| Petrol comes off near the top of the column. Does the list above describe petrol? | Fuel oil comes off near the bottom of the column. Does the list above describe fuel oil? |
The fractions are now ready for piping to the next areas within the refinery. Some fractions require very little additional processing. However, most molecules require much more processing to become high-value products.
Conversion: cracking and rearranging molecules
Some fractions from the distillation towers need to be transformed into new components . This is where a refinery makes money, because the low-value fractions that aren't in great demand can be converted to petrol and other useful chemicals.
The most widely used conversion method is called cracking because it uses heat and pressure to "crack" heavy hydrocarbon molecules into lighter ones. A cracking unit consists of one or more tall, thick-walled, reactors and a network of furnaces, heat exchangers and other vessels. Catalytic cracking, or "cat cracking," is the basic petrol-making process. Using intense heat (about 600°C), low pressure and a powdered catalyst (a substance that speeds up a chemical reaction), the cat cracker can convert most of the heavy fractions into smaller more useful molecules.
Some refineries also have cokers, which use heat and moderate pressure to turn the really heavy fractions into lighter products and a hard, coal like substance that is used as an industrial fuel.
Cracking and coking are not the only forms of conversion. Other refinery processes, instead of splitting molecules, rearrange them to add value. Alkylation makes petrol components by combining some of the gaseous byproducts of cracking. The process, which essentially is cracking in reverse, takes place in a series of large, horizontal vessels.
Reforming uses heat, moderate pressure and catalysts to turn naphtha into high-octane petrol.
Treatment: the finishing touch
Today, a major portion of refining involves blending, purifying, fine-tuning and improving products to meet specific requirements. To make petrol, refinery workers carefully blend together a variety of hydrocarbons. Technicians also add performance additives and dyes that distinguish the various grades of fuel. By the time the petrol is pumped into a car it contains more than 200 hydrocarbons and additives.
Example: Petrol companies produce different blends of fuels to suit the weather. In winter, they put in more volatile hydrocarbons (with short carbon chains) and in summer they add less volatile hydrocarbons to compensate for the higher temperatures.
