Jilin Petrochemical Company seized the favorable opportunity for warming weather and recently began organizing energy-saving reforms for cracking furnaces of No. 1, No. 2 and No. 6 crackers in the 700,000-ton ethylene plant to further reduce energy consumption of the plant. In order to recover more high-level thermal energy of the cracked gas, the transformation will increase the heat exchange tubes of the quench heat exchanger by 14 on the original basis, so that the effective heat transfer length will increase by 1200 mm. After the heat transfer area is increased, the outlet temperature of the quench heat exchanger can be reduced by 30°C. SINGSUN ELECTRONIC SCIENCE & TECH CO.,LTD , https://www.singsunautomatic.com
