30万t/a PVC装置乙炔站自控仪表改造

Modifications on automatic control instruments of acetylene generating station for 30 000 t/a PVC production facility

对30万t/a PVC装置乙炔站的DCS供电系统、发生器上储斗充氮置换及加料自控系统、次氯酸钠配制系统进行了改造,通过改造提高了乙炔站生产的可靠性,消除了安全隐患,降低了劳动强度。

Modifications were made on the DCS power supply system, automatic control sys- tems for the nitrogen replacement of upper hopper and acetylene generator feeding, and the sodium hypochlorite preparation system in the acetylene generating station for 30 000 t/a PVC production facility. Thus, the production reliability of acetylene generating station was improved, the hidden hazards were eliminated, and the labour intensity was reduced.
