refinería

A refinería, also known as an oil refinery or petroleum refinery, is an industrial process plant where crude oil is processed and refined into more useful petroleum products such as gasoline, diesel fuel, asphalt base, heating oil, kerosene, and jet fuel. The process involves several stages, including atmospheric and vacuum distillation, conversion processes, and treatment processes.

The first stage of refining is distillation, where crude oil is heated to separate it into fractions based on their boiling points. Atmospheric distillation involves heating crude oil to around 350°C (662°F) and then cooling and condensing the vapors to produce various fractions. Vacuum distillation is used to further separate the heavier fractions by reducing the pressure, allowing for the separation of heavier hydrocarbons.

Conversion processes are used to upgrade the lighter fractions and convert them into more valuable products. These processes include catalytic cracking, which breaks down heavy hydrocarbons into lighter ones, and reforming, which rearranges the molecular structure of hydrocarbons to produce high-octane gasoline.

Treatment processes are used to remove impurities and contaminants from the refined products. These processes include hydrotreating, which removes sulfur and other impurities through a catalytic reaction with hydrogen, and sweetening, which removes sulfur compounds from the products.

Refinerías play a crucial role in the global energy supply, as they convert crude oil into the fuels and products that power transportation, industry, and homes. The refining process is complex and requires advanced technology and skilled personnel to ensure the safe and efficient production of high-quality petroleum products.
