Abstract

The scheme of recycling dry gas of refining plant for using as ethylene cracking material was introduced, analogue computations were made with SPYRO software on the composition of cracking gas produced with naphtha and aromatics blended dry gas respectively, and analysis and comparison were made on economics of the two schemes. Result showed that comparing with naphtha, the yields of ethylene and propylene in cracking products were much greater with aromatics blended dry gas as material.
