电石法聚氯乙烯行业履约对策建议

Countermeasures and suggestions on the implementation of Minamata Convention on Mercury for calcium carbide based PVC production process

电石法聚氯乙烯生产是我国用汞量最大的工艺,也是我国履行《关于汞的水俣公约》的重点行业。解析了公约对电石法聚氯乙烯生产的管控要求,调研了我国该行业发展现状和低汞无汞替代技术研发应用情况,针对产能过剩、低汞触媒应用不力和无汞催化剂推广缓慢等行业面临的问题,提出了严格控制新增产能、建立信息报告机制、加强低汞触媒监管和加快无汞催化剂评估应用的履约对策建议。

The calcium carbide based PVC production process involves the employment of the largest amount of mercury in China. It is also the key industry to fulfill the Minamata Convention on Mercury. The control requirements of the Convention on calcium carbide based PVC production process are analyzed. The current situation of calcium carbide based PVC industry, and the development and application of low-mercury and non-mercury alternative technology are investigated. To solve the problems existing in the PVC industry, such as excess capacity, ineffective application of low- mercury catalyst and slow promotion of mercury-free catalyst, strict control of production capacity, establishment of information reporting mechanism, strengthening supervision of low-mercury catalyst and speeding up the assessment and application of mercury-free catalyst are proposed as countermeasures and suggestions on the implementation of Minamata Convention on Mercury.
