Zhongyuan Petrochemical's ethylene yield and diene yield are among the best in the chemical industry

       By strengthening lean management, optimizing the structure of raw materials, and adjusting the cracking depth, the ethylene yield and diene yield of Zhongyuan Petrochemical's ethylene plant reached the highest 38.6% and 53.6% respectively. As of the end of 2020, it has ranked among the top of Sinopec's chemical sector for 9 consecutive years .

　　Ethylene yield and diene yield are both important economic and technical indicators of ethylene plant, and they are a concrete manifestation of management level and operation level. The company actively guarantees raw materials. When the supply of raw materials is very tight, the company has strengthened coordination to ensure timely and sufficient supply of raw materials. Do a good job in the optimization of the raw material structure, achieve "daily analysis, daily balance, and daily optimization", conduct special analysis on the optimization of ethylene raw material structure every month, overcome the difficulties of raw materials and uneven quality, and use high-quality raw materials and light hydrocarbon ratio Reach 33%, and the proportion of light naphtha reaches 28%, which improves resource utilization efficiency.

The company strengthens production organization, takes the stable, long-term and optimal operation of the device as the top priority of the work, maintains a safe and high-pressure situation, and continuously enhances the safety awareness of employees, improves safety skills, strengthens on-site supervision, and overcomes extremes through increased training. The adverse effects of the weather ensure stable and high yield, and provide a guarantee for increasing the yield of ethylene and diene. At the same time, actively carry out technical research, take effective measures to adjust the cracking depth of the cracking furnace, ensure the safe and stable long-term operation of the cracking furnace, and continuously increase the load of the ethylene plant.
