The refining process takescrude oil and separates it into useable products. These products range from lubricants to LPG, gasoline, kerosene, residual and distil- late fuels, coke, asphalt, solvents, and petrochemical feedstock. The refining process starts with fractionating, where the crude is sent through two distillation units. The first unit is atmospheric distilla- tion, which separates and recovers the lighter fractions from the fresh crude oil. The reduced crude feed is then sent to the second distillation unit, vacuum distillation, where light, medium, and heavy lube oil is separated.The...

The heart of every refinery isthe crude distillation unit. In a crude unit, the oil is heated and the different hydrocar- bon compounds are separat- ed by a process called distil- lation. DistillationӔ means that, at different tempera- tures, the various hydrocar- bon compounds will boilӔ off and be separated from the feedstock. It is important to note that the distillation process is the most common process found in a refinery. Distillation towers are found in almost every type of unit and are used to separate the various hydrocarbon fractions.The atmospheric crude distil-lation tower is very...
