Summary of automation transformation for safe production of special resin
In order to improve the safety of specialized resin production,a series of automation im-provement measures were taken:① The vinyl chloride recovery and compression system was renovated,shut-off valves were added to the compressor inlet and return pipelines,and the DCS program was opti-mized,the manual start-stop of compression system was upgraded to a DCS one-click start-stop;②Safety upgrades were made to the venting pipeline of pressure vessels,pressure gauges were added be-tween the rupture disc and the safety valve;③Remote control points were added to the vinyl chloride transportation pipeline and the transportation program was optimized;④Remote shut-off valves were added on the water injection pipelines of vinyl chloride spherical tanks and storage tanks,manual on-site operation of water injection was upgraded to remote automatic operation.
