The Factors Analysis And Countermeasures Discussion Of Extending The Butadiene Plant’s Running Cycle

Conditions for the Lanzhou Petrochemical Company butadiene plant operating cycle is shorter.In this paper, through the operation of the butadiene plant in recent years were summarized,conducted a comprehensive analysis of in terms of abnormal operating conditions adjustment method, polymerization inhibitor mechanism, changes in the composition of raw materials currently on the system impact,self-polymerization mechanism of1,3-butadiene, B-T101tower internal structure and B-T103tower pressure rises he equipment operation, etc. Mainly due to the extraction system pressure increases, resulting in the system not high load operation.On the basis of a comprehensive analysis,Finded a set of emergency measures to adapt and daily management of the device, thereby improving plant operation cycle.
