As of July 27, Zhenhai Refinery's second set of catalytic units has been overhauled for more than a month
.
During the maintenance period, the Refinery No.
1 completed the project of increasing production of propylene and eliminating bottlenecks with high quality.
Through the comprehensive transformation of the cooling system of the refined propylene tower, all the original 16 dry air coolers were replaced with 6 high-efficiency composite air coolers.
A water-cooled heat exchanger is added to the top of the propane tower to solve the problem of insufficient cooling load in the high temperature season in summer and eliminate the bottleneck of increasing propylene production
.
After the start of the plant, the plant operation team thoroughly optimized the production based on the goal of increasing the production of propylene through a comprehensive analysis of the working conditions of the catalytic plant
.
Recently, the yield of the second set of catalytic units has reached a maximum of 7.
1%, and the daily output of propylene has increased by 132 tons compared with 2019.
The operation performance of the unit will reach a "new height"
.
