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.

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.
