ABSTRACT
Refineries rely on four major chemical processing operations in addition to the backbone physical operation of fractional distillation, in order to alter the ratios of the different fractions. These are normally called the Five Pillars of petroleum refining:
Pillar 1: Fractional distillation Pillar 2: Cracking Pillar 3: Unification (alkylation)
