Crude Oil To Chemicals enhances the conversion of oil into petrochemical feedstocks with fuels becoming a byproduct

For most of the twentieth century, crude oil was primarily refined into transportation fuels—gasoline, diesel, and jet fuel—with petrochemicals representing a secondary, opportunistic yield. The crude-to-chemicals (COTC, C2C, CTC, TC2C) concept inverts this hierarchy entirely: the refinery is redesigned from the ground up to maximize the conversion of crude into petrochemical feedstocks, with fuels becoming the byproduct rather than the objective. Conventional refineries yield only 10–20% chemicals from a barrel of crude; integrated COTC complexes now achieve 40–50% commercially, with advanced configurations targeting 70% and above.
