China Petroleum & Chemical News Network reported that after entering July, Yangzi Petrochemical Company strictly checked the "four gases" (hydrogen, nitrogen, liquefied gas, natural gas) early warning measures in response to the characteristics of continuous high temperature weather and volatile climate, and adopted "active and regular inspections and implementation of determinations.
" The method of “personal customization and improvement of accident plans” persists in daily on-the-job inspections, and organizes technical forces to conduct comprehensive safety inspections on the “four gas” systems, especially for the “four gas” leaks at high points, remote points and dangerous points.
Check notifications, implement rectification measures and accident plans
.
Yangzi Petrochemical organized a "Four Gas" system safety inspection team composed of HSE management offices, professional functional management offices, workshops, and joint equipment technicians.
First, they identified the key parts that are prone to leaks, and formulated measures for dozens of key parts.
Plan for regular inspections, and report and rectify leaks in time
.
Secondly, confirm which parts are most easily overlooked in the accident plan, and formulate corresponding measures accordingly.
Inspectors use the time of daily on-the-job inspections and professional inspections of process equipment to focus on high points, remote points and dangerous points
.
They also divided the "Four Gas" system safety responsibility area, designated a special person to be responsible, the team improved the ledger, and implemented the "Four Gas" system inspection and shift system
In view of the characteristics of the natural gas system usage, Yangzi Petrochemical Aromatics Plant, with the assistance of the company's relevant departments, regularly holds special technical analysis meetings to stabilize the usage in a timely manner
.
In view of the characteristics of the high-load operation of the device during the gold production season in the third quarter, the reasons for the possible leakage of the "four gases" were analyzed, and preventive investment was made to prevent possible leakage accidents
At the same time, in order to avoid leakage caused by human subjective factors, on the one hand, they strengthened the quality control of spare parts, improved the procurement regulations of related spare parts, and strictly prevented inferior spare parts from entering the site
On the other hand, improve the technical and professional quality of relevant personnel, strictly control the quality parameters of gaskets, flanges and various valves, and concentrate on eliminating a batch of leaks during the full implementation of the summer operation mode.
The workshops and joint installations also use the weekly "four gas" inspection days to strengthen the inspection, inspection, and maintenance of equipment, storage tanks, fuel gas and other pipelines, and attach great importance to the corrosion of equipment caused by the processing of high-sulfur crude oil, hydrogen sulfide Monitoring and management of problems, and drills of emergency treatment plans in the sulfur recovery device to improve the on-site emergency response capabilities of employees
