Atmospheric distillation of crude oil

Refining of crude oils essentially consists of primary separation processes and secondary conversion processes. The petroleum refining process is the separation of the different hydrocarbons present in the crude oil into useful fractions and the conversion of some of the hydrocarbons into products having higher quality performance. Atmospheric and vacuum distillation of crude oils are the main primary separation processes producing various The top product from the atmospheric distillation column is a mixture of hydrocarbon gases, e.g., methane, ethane,
