Escopo e aplicabilidade

This standard applies to the production, storage, and emergency response of vinyl chloride using the acetylene method. It is mandatory for enterprises engaged in the production of vinyl chloride by acetylene. It does not apply to the ethylene oxychlorination process for vinyl chloride production. It covers safety requirements for facilities, equipment, and operational processes.

Requisitos técnicos

The standard outlines comprehensive safety requirements for the production of vinyl chloride via the acetylene process. It specifies general requirements including safety management, site selection, building structures, piping, and electrical instrumentation. Facilities must implement intelligent management systems for personnel positioning and equipment monitoring. It also references GB 45673 for safety production informatization. For production safety, the document details specific operational parameters for mixed dehydration, vinyl chloride synthesis, purification, compression, and distillation. It mandates strict controls on gas purity, temperature, and pressure, along with automated interlock systems. Equipment and pipelines in contact with vinyl chloride must not use materials containing 65% or more copper. Storage safety requirements dictate strict limits on tank capacities and filling ratios. Vinyl chloride storage tanks must be equipped with remote control valves, spray facilities, and emergency cut-off systems. Single tank capacity for new projects shall not exceed specific limits, and filling must not exceed 85% of volume. Emergency response protocols are established for leaks, fires, and poisoning incidents. It requires the implementation of emergency plans according to GB/T 29639 and proper equipping of rescue materials as per GB 30077. Specific isolation distances must be maintained during leakage incidents to ensure public safety.

Métodos de ensaio

The standard describes verification methods rather than traditional laboratory testing. Verification involves reviewing project construction documents, management systems, on-site layouts, real-time control system parameters, and historical records. It also includes checking equipment maintenance logs, safety facility ledgers, and emergency drill records to ensure compliance with the specified safety requirements.
