In June, Sino-Korea Petrochemical's key technical and economic indicators ethylene and diene yields hit a record high. Among them, the ethylene yield was 32.43%, an increase of 0.04 percentage points from the historical best level, and the diene yield was 0.19 percentage points higher than the historical best level.

In early May, Sino-Korea Petrochemical No. 9 cracking furnace was successfully put into operation. After the furnace is put into use, the raw material structure is further optimized, so that the ethylene device can flexibly control the coking cycle of each cracking furnace, reducing unplanned shutdown of the furnace. Entering June, the ethylene plant cracking furnace long-term operation research team has overcome the unfavorable factors such as the decline in the quality of naphtha raw materials, high temperature, and the increase in circulating water temperature, and optimized the cracking depth of the No. 9 cracking furnace and the No. 8 cracking furnace put into use after maintenance. Dilution ratio, etc., ensure the optimal working conditions of the cracking furnace and make the ethylene plant stable and high-yield.

In June, Sino-Korea Petrochemical's ethylene output was 73,200 tons, an increase of 27,000 tons compared with the same period last year, and the increase in output was 3.83%.
