How does offshore oil extraction work?

Once the offshore drilling platform is built, some method of extracting the oil and gas from beneath the ocean and moving it to the surface without losing it must be developed. To drill without water flowing into the hole or having all the oil surge up into the ocean, a subsea drilling template is used.

What are the three stages of oil refining?

Three major types of operation are performed to refine the oil into finished products: separation, conversion and treating.

What are the methods of oil refining?

A typical oil-refining process consists of several processing units such as distillation, cracking, coking, reforming, and posttreatment and refining of the products.

Which country is the largest refinery of oil?

The United States
The United States had the world’s largest oil refinery capacity as of 2020, at 18.14 million barrels per day.

How do offshore oil rigs stay in place?

The platforms can be kept in place through large, heavy anchors, or through the dynamic positioning system used by drill ships. With a floating production system, the wellhead is actually attached to the seafloor once the drilling is completed, rather than being attached up to the platform.

How do offshore oil rigs get oil to shore?

The oil from the rigs is usually transported to shore via an undersea pipeline. With hundreds of rigs offshore and all the air, water, and undersea travel, you can imagine that Aberdeen is a busy place! On the rigs, there are four main categories of jobs: production, maintenance, and service.

Are oil refineries bad for the environment?

Air pollution hazards: Petroleum refineries are a major source of hazardous and toxic air pollutants such as BTEX compounds (benzene, toluene, ethylbenzene, and xylene). Refineries also release less toxic hydrocarbons such as natural gas (methane) and other light volatile fuels and oils.

What is edible oil refining?

The main aim of edible oil refining is to make the oil suitable for human consumption. Oil refining process removes these unwanted constituents without damaging glycerides and with minimum loss of desired constituents, which in turn improves flavor, odor, color and stability. …

Do oil rigs touch the sea floor?

Mobile Drilling Platforms. A jack-up rig can raise and lower itself on three or four massive “legs.” Oil companies float these structures out to a drill site and then lower the legs until they touch the sea floor and elevate the rig out of the water.
