The Refinery Process
Petroleum refining begins with the separation of crude oil into different fractions through a process called ‘distillation.’ The fractions are treated further to convert them into a mixture of marketable products through a large list of methods and processes: reforming, polymerization, alkylation, cracking and isomerisation. These new compound mixtures are separated afterwards, by using solvent extraction and fractionation. Through the following later stages, sulphur and other impurities are removed using hydro-treatin
