An oil refinery is an integral part of the oil and gas industry, taking crude oil and transforming it into a variety of highly useful products such as gasoline, kerosene, and jet fuel. In order to achieve this, the refinery uses specialized processes called distillation and cracking that separate the components of crude oil into multiple useful derivatives.
The refining process begins with crude oil, which may be gathered from drilling efforts into underground oil shale layers, or produced from wells and reservoirs in the ocean. The oil is then transferred to refineries, often in tankers and pipelines, which are typically large and highly efficient facilities.
Once the crude oil has been refined, the end products are divided into two halve—the light side, which includes products such as gasoline, kerosene, high-octane aviation fuel, and low-sulfur diesel, and the heavy side, which includes heavier distillates like fuel oils, heavy waxes, and lube oil additives.
The distillation and cracking processes used to refine the crude oil occur in tanks and separators, the first of which purifies the incoming petroleum to separate out volatile contaminants, such as sulfur and nitrogen. Once purified and heated, the crude oil is separated into various components, with each component boiled off at different temperatures and pressures.
Further purification of the distillates occurs in a catalytic reforming process that helps separate and rearrange the residual molecules into higher value derivatives for gasoline, diesel, and other products.
Finally, to ensure a safe and consistent product is created, all the refined products from the facility must go through a series of quality control tests, including viscosity, flash point, and sulfur content.
In the current oil and gas market, the differences between the production costs and market prices of various refined petroleum products help oil refineries and traders hedge their exposure to crude oil prices. This difference, known as the crack spread, also helps refineries properly price their products, as well as anticipate their inventory to give an accurate sense of the supply and demand equation.
Throughout the entire refining process, it is important that all safety standards and standards set by governmental agencies and quality assurance groups are followed. These standards help protect the health and safety of refinery workers and their surrounding environment.
In conclusion, oil refineries are a critical component of the oil and gas industry, taking crude oil and turning it into multiple refined products such as gasoline, kerosene, and diesel. Through the combined efforts of distillation and cracking processes, as well as quality control tests, refineries are able to process the crude oil in a safe, efficient, and consistent manner.
