| Abstract: | 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. |
