Abstract: To solve the problem that the separator at the top of gas phase reactor in a certain polypropylene unit often needs to drain propylene-containing mixture,the influences of air lock sealing materials,the opening degree of air lock pressuring propylene valve,the yield ratio,the cooling pump flushing propylene in a closed environment and the time setting of airlock process on the liquid level of the separator at the top of gas phase reactor are analyzed,and hence the production process of the unit is optimized,which results in a significant reduction in the unit consumption of propylene and production costs and increases approximately two million RMB in annual profit.
