What are the three stages of oil refining?

All refineries have three basic steps: separation, conversion and treatment. During the separation process, the liquids and vapors separate into petroleum components called factions based on their weight and boiling point in distillation units.

What is the first stage of refining?

Distillation involves the separation of materials based on differences in their volatility. This is the first and most basic step in the refining process, and is the precursor to cracking and reforming. Cracking involves breaking up heavy molecules into lighter (and more valuable) hydrocarbons.

What were the 3 products of refining oil?

Refined Petroleum Products and Their Uses

Gasoline and diesel are used as fuels for motor vehicles. Kerosene is used as jet fuel. Naphtha is a major petrochemical feedstock. Heating oil is used to heat.

What are the 3 stages of oil and gas?

Oil and gas companies can generally be divided into three segments: upstream, midstream, and downstream. Upstream firms deal primarily with the exploration and initial production stages of the oil and gas industry.

What is the process of refining the oil?

The crude is heated by a furnace and is sent to a distillation tower, where it is separated by boiling point. Then the material is converted by heating, pressure or a catalyst into finished products including fuels like gasoline and diesel, and specialty products like asphalt and solvents.

Petroleum and its refining - Chemistry



What are the five basic refining processes?

These processes include:
  • Decomposition (dividing) by thermal and catalytic cracking;
  • Unification (combining) through alkylation and polymerization; and.
  • Alteration (rearranging) with isomerization and catalytic reforming.

What are the types of refineries?

There are four types of refineries – topping, hydro-skimming, conversion, and deep conversion refineries. Depending on the market a refiner is aiming at, each refinery has its unique design to ensure their production conforms to their host country's set standards.

What are upstream and downstream?

Simply put, upstream works include the exploration and production of crude oil and natural gas, whilst downstream refers to the processes applied after extraction through to it being delivered to the customer in whatever format required.

What are upstream and downstream in oil production?

Upstream oil and gas production is conducted by companies who identify, extract, or produce raw materials. Downstream oil and gas production engages in anything related to the post-production of crude oil and natural gas activities.

What is upstream and downstream and midstream?

'Upstream' is about extracting oil and natural gas from the ground; 'midstream' is about safely moving them thousands of miles; and 'downstream' is converting these resources into the fuels and finished products we all depend on.

What are the stages involved in evolution of crude oil?

Therefore, petroleum formation processes are slightly different in various petroleum systems. Nonetheless, there are some generic stages of hydrocarbon formation, namely: diagenesis, catagenesis and metamorphism.

Is FPSO upstream or downstream?

FPSOs integrate upstream, midstream, and downstream activities. They extract oil from the well, process and store it on board and deliver the partially treated crude oil to tankers for transportation to a refinery.

What does midstream mean in oil and gas?

Midstream refers to points in the oil production process that falls between upstream and downstream. In particular, midstream activities include the storage, processing, and transportation of petroleum products. These may include companies that specialize in operating tanker ships, pipelines, or storage facilities.

How is crude oil separated?

Fractional distillation is used to separate crude oil into simpler, more useful fractions. A fraction of crude oil is a group of hydrocarbon molecules of similar size with similar boiling points . Their similar boiling points mean that they can be separated by fractional distillation.

Where is oil refined?

An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into useful products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha.

How is crude oil extracted?

Today, petroleum is found in vast underground reservoirs where ancient seas were located. Petroleum reservoirs can be found beneath land or the ocean floor. Their crude oil is extracted with giant drilling machines. Crude oil is usually black or dark brown, but can also be yellowish, reddish, tan, or even greenish.

How long does it take to refine oil?

Turning crude oil into refined gasoline

Generally, every 30,000-barrel batch takes around 12 to 24 hours to undergo through analytical testing and pass quality control. A key stage is ultra-heating the crude to boiling point, with a distillation column used to separate the liquids and gases.

Why does crude oil require refining?

Why Do We Refine Crude Oil? Crude oil cannot be used as it occurs in nature, other than burning for fuel, which is wasteful, It must be refined to manufacture finished products such as gasoline and heating oil.

How is an oilfield different from an oil refinery?

Field Facilities

An oilfield facility is different from a refinery or chemical plant in a number of ways. The process is simpler in a facility, consisting not of chemical reactions to make new molecules, but of: Phase separation. Temperature changes.
