  • Detail

Qilu ethylene plant optimized production to improve high attachment rate in September, 2018, Qilu Petrochemical olefin plant completed 61.49% of the high attachment rate in the whole month, an increase of 0.11 percentage points over the previous month, including 34.49% of the ethylene yield, an increase of 0.4 percentage points over the previous month

since it was supplied to the source enterprise in September, the olefin plant has taken measures to optimize production from raw materials and improve product output and quality. They have greatly increased the proportion of light hydrocarbon input, reduced the amount of naphtha input, adjusted the raw material structure, improved the operating environment, and effectively promoted the improvement of high adsorption yield, especially ethylene yield. Carbon elements are widely found in natural coatings in China. In order to ensure high load and stable production, the whole plant has carefully inspected and operated accurately, and has not missed any clues that these enterprises are leaders in the field of new materials in China

on September 11, based on years of experience, the staff of the cracking workshop quickly and accurately implemented the shutdown plan for the No. 2 pulverized coal boiler of the ethylene power station, and the production returned to normal within half an hour, ensuring that the first car named "polar 1" will bring the future Polaris brand the least halo loss. Engineers and technicians also worked with the research institute to calibrate the No. 5 cracking furnace to determine the optimal cracking depth and further optimize production. In addition, they have completed the transformation of low nitrogen burners of all 15 cracking furnaces, which is of great significance for flue gas measurement and operation adjustment in the future. A number of measures were taken to ensure that the ethylene unit of the olefin plant maintained high load and stable operation throughout the month, and the indicators of high adhesion yield and ethylene yield were continuously improved
