The calcium carbide polyvinyl chloride (PVC) industry leading group for mercury pollution control and expert group meeting was held in Beijing on March 4. The meeting preliminarily determined the mercury pollution prevention and control targets this year, and further increased the promotion and application of low-mercury catalysts. The use of low-mercury catalysts exceeded 4,000 tons, accounting for about 35% of the mercury catalysts, and at the same time increased the research and development of mercury-free catalysts.
According to reports, this year the China Petroleum and Chemical Industry Federation and China Chlor-Alkali Industry Association will fully organize the calcium carbide process polyvinyl chloride industry to do a good job of mercury pollution prevention and control, actively promote the promotion and application of low-mercury catalysts, and promote the efficient mercury recovery technology, popularization The rate of more than 20%; promote low-mercury catalyst production and recycling of waste mercury catalyst new technology demonstration project construction, recycling waste mercury catalyst more than 4,000 tons.
At the same time, the Ministry of Industry and Information Technology was promoted to issue the “Standard for Low-Ignition Catalyst Products†as soon as possible to prepare for the use of low-mercury catalysts in the entire industry in 2015; the “Ca-Chrome PVC industry prevention and control plan for mercury pollution†was revised and improved to guide the prevention and control of mercury pollution in the industry; The investigation of mercury resources will be carried out to lay the foundation for the scientific and rational utilization of mercury resources and the formulation of a correct development strategy; relevant organizations will be organized to conduct research on the negotiation of international mercury conventions and provide technical support for the negotiations.
Zhou Zhuye, vice president of the Petrochemical Federation, said that the calcium carbide mercury pollution problem of the calcium carbide process can now be discussed on the table, indicating that the industry's self-restraint requirements for sustainable development are a great improvement. He proposed suggestions on the prevention and control of mercury pollution from the calcium carbide process in the polyvinyl chloride industry. The first is to further raise awareness. The current understanding of mercury pollution has changed a lot. However, to solve the problem of mercury pollution, it is necessary for the whole industry to pay attention, support and advance. The situation facing the analysis industry is quite severe. Apart from the constraints of the external environment on the industry, from the perspective of self-discipline and sustainable development of the industry itself, enterprises must raise their awareness.
Followed by solidarity and cooperation. Some companies, especially leading companies, are actively working to promote the prevention and control of mercury pollution, but some companies are waiting to see it. The promotion of mercury pollution prevention and control is a major event in the industry. It requires the whole industry to turn into a force, to give up self, and to care for me. At present, the time has come when the industry must face the need for industry-wide cooperation and joint efforts to achieve breakthroughs to solve the industry's life and death problems.
Zhou Zhuye also stressed that it is necessary to pay attention to the problem of recycling waste mercury, use the stock mercury, and achieve a balance of mercury, which is also one of the important means for the industry to strive for space and time.
