Steam Cracking

A high-tech process map showing how naphtha, gas oil, ethane, butane, pentane, and propane feed into the cracking furnace, with ethylene and propylene as the major downstream platform molecules.

Thermal
Cracking Olefin Platform
Liquid Feed Naphtha i Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from crude oil refining and is commonly used as a steam cracker feedstock.
Refinery Stream Gas Oil
NGL Feed Ethane
NGL Feed Butane
NGL Feed Pentane
NGL Feed Propane
PDH UNIT i Propane dehydrogenation, or PDH, is a route for producing propylene from propane.
High-temperature conversion of hydrocarbon feedstocks into lighter olefins

Feedstock Flexibility

Naphtha, gas oil, and natural gas liquids feed the furnace depending on regional economics and supply position.

Olefin Outputs

Ethylene and propylene become the major branching points for downstream petrochemical derivatives.
