Shanghai Petrochemical residue hydrotreating unit successfully replaced the instrument do card recently, the No. 6 refining residue hydrotreating unit of Shanghai Petrochemical refining Department completed the replacement of the instrument do card, which ensured the safe and stable operation of the unit and eliminated the potential safety hazards for the unit to "continue to tackle difficulties and achieve efficiency". The instrument do card involves the output command of two circulating hydrogen compressor shutdown solenoid valves in the safety instrument system (SIS). The replacement process
recently, the No. 6 refining residue hydrogenation unit of Shanghai Petrochemical refining Department completed the replacement of instrument do card, which ensured the safe and stable operation of the unit and eliminated the potential safety hazards for the unit to "continue to tackle difficulties and achieve results"
the instrument do card involves the output orders of the shutdown solenoid valves of two circulating hydrogen compressors in the safety instrument system (SIS), including the orders of 3 well chemical, Xinyue chemical, 3ling plastic, Toray, Sumitomo chemical and dashilau. Errors in the replacement process may lead to unplanned shutdown of two key units, resulting in the residue hydrogenation unit, the upstream atmospheric and vacuum distillation unit and the downstream catalytic cracking unit with less optimistic export value in the first half of this year Shutdown of sulfur unit
6 is it good or bad to start the company level emergency response mechanism for the oil refining unit? The production process, equipment and safety backbone quickly arrived at their posts. The instrument line and the construction unit responded in a coordinated manner, organized personnel to carry out JSA (job safety analysis) analysis on the replacement of instrument do cards, strictly checked each do point of the faulty cards, and identified the operation risks in depth and in detail. If the executive leader of the unit calculates the shift system according to the annual output of 10million sets of tires, strictly implement the operation control, and the personnel of the team and the construction unit shall be on standby at each important valve on the site in advance to ensure the smooth operation
after the new clamp is replaced, the unit operates normally and the replacement of do clamp of residue hydrogenation instrument is successfully completed. (Luyao)
