Yangzi Petrochemical rubber products continue to maintain stable and high production

This newspaper report (Correspondent Tao Yan, Wang Yu, Xie Yu, Reporter Xu Ning): Yesterday, the reporter learned from Yangzi Petrochemical that the company’s rubber department has maintained stable and high production on two sets of units since the beginning of the year, with cumulative production and sales of styrene-butadiene rubber and cis-bentene rubber reaching 52k tons in the first quarter, a year-on-year increase of 5.4%.

Since the beginning of the year, Yangzi Petrochemical’s rubber department has focused on “stable and high production, quality improvement, and efficiency enhancement,” strengthening process optimization, equipment assurance, and refined management, achieving double success in styrene-butadiene rubber and cis-bentene rubber. “We precisely target continuous optimization of production processes, addressing issues such as low temperature in the latex discharge tank and poor butadiene recovery in the styrene-butadiene rubber area by organizing professional teams to improve discharge tank temperature technology, effectively enhancing latex stability and extending the operation cycle of degassing towers,” introduced the head of Yangzi Petrochemical’s rubber department. Meanwhile, they accurately control the fluctuation range of the polymerization reaction temperature in the cis-bentene rubber unit, finely adjust catalyst ratios to the optimal activity range, and precisely manage raw material impurities to ensure the stable and efficient operation of the polymerization system.

“In terms of stable equipment operation, we strengthen full lifecycle management of equipment, listing special inspection checklists for pump seal configurations and operation maintenance, conducting comprehensive inspections of on-site pumps, and promptly implementing closed-loop rectifications upon discovering issues,” said the head of Yangzi Petrochemical’s rubber department.

In process operations, Yangzi Petrochemical’s rubber department deepens internal and external operation coordination and refined inspection, continuously improving operational skills through small indicator competitions and technical breakthroughs, ensuring that the two units operate safely, stably, and meet standards under high load, providing solid support for stable production and efficiency. Meanwhile, they continue to carry out special labor competitions for post-treatment, with each team strengthening supervision over inspection quality, alarm counts, and process indicator pass rates. The styrene-butadiene rubber area saw a 30% year-on-year decrease in abnormal inspection cases, a 20% decrease in total alarms, and the process indicator pass rate increased to 99.72%.
