This paper briefly introduces the influence of high quench oil viscosity on the ethylene plant,and analyzes the reason of high quench oil viscosity through the viscosity increasing mechanism,pyrolysis raw material composition and process operation.Combined with the actual operation of an ethylene unit,the optimization treatment was carried out in the aspects of raw material properties,process adjustment and viscosity reduction tower adjustment,which finally made the quench oil viscosity stable control in a reasonable range,and summed up the process parameters under the condition of optimal quench oil viscosity.
