The comprehensive energy consumption of the butadiene extraction unit of Zhongke Refinery has reached a new low

Recently, the comprehensive energy consumption of the butadiene extraction unit of Zhongke Refinery has hit a new low since the unit was put into operation, and has been ranked the best in the system for consecutive May this year
.
As of the end of June, the cumulative production of butadiene was 58,300 tons, 3.
7% higher than the original plan, exceeding the production task in the first half of the year
.

The device actively takes advantage of the favorable conditions of high upstream load.
While maintaining high-load operation, it takes multiple measures to strictly control the product yield and continuously reduce energy consumption and material consumption
.
They carried out small-index competitions such as operation stability rate, operation pass rate, alarm statistics, etc.
, and the "leak point" competition between teams and groups continued to rectify the phenomenon of "running and dripping" and stabilize the operation of the device
.
By strictly controlling the replacement effect of the pump after cleaning the filter, regularly switching the high-concentration pump of butadiene, and dynamically adjusting the injection amount of the polymerization inhibitor in the weight-removing tower, the loss of materials and products caused by polymerization is reduced
.

At the same time, they effectively reduced the butadiene content in by-products through fine operations, and kept the butadiene product yield above 98%
.
The average product yield of the unit this year is 98.
78%, an increase of 1.
31% over the same period in 2021
