Abstract

Co-cracking is a process where the mixtures of different hydrocarbon feed stocks are cracked in a steam pyrolysis furnace

and widely adopted in chemical industries. In this work

the simulations of the co-cracking of ethane and propane

and LPG and naphtha mixtures have been conducted

and the software packages of COILSIM1D and SimCO are used to account for the cracking process in a tube reactor. The effects of the mixing ratio

coil outlet temperature

and pressure on cracking performance have been discussed in detail. The co-cracking of ethane and propane mixture leads to a lower profitability than the cracking of single ethane or single propane. For naphtha

cracking with LPG leads to a higher profitability than single cracking of naphtha

and more LPG can produce a higher profitability.
