Ethylene from Naphtha

Abstract

Naphtha boils in the gasoline boiling range ie C5-220oC. A steam to hydrocarbon weight ratio used for cracking naphtha is about 0.5:1. Reaction is performed at a coil outlet temperature of 850'C. Furnace design varies with feed type. Fractionation is carried out with C1 as being the separated, followed by successively higher carbon numbers. is essentially identical to the previous description.
