Optimization of ethylene cracking process by COILSIM
In order to improve the ethylene yield of the existing unit,reduce the energy consumptionand obtain the maximum economic benefit with the minimum investment,the E1 unit used the remaining propane after the startup of the E3 unit to mix into the propane for cracking in the light hydrocarbon cracking furnace to meet the purpose of cracking propane alone in the EF-111D furnacethrough the optimization of auxiliary measures and the application of COILSIM simulation software,which greatly increased the ethylene yield of the unit,improvedthe economic benefit,and reducedthe energy consumption of the unit.
