For a long time, vinyl chloride and polyvinyl chloride devices in the tail gas of the condensation of vinyl chloride pollution of the environment, material loss, always plagued the PVC industry. In recent years, some companies have begun to use membrane recovery technology and pressure swing adsorption technology to solve this problem. These two technologies are stable in operation, low in cost, and highly efficient in the recovery of vinyl chloride. The content of exhaust gas containing 40% to 60% of vinyl chloride gas is below 1% after recovery. Taking the 30,000-ton/year PVC plant as an example, the membrane adsorption technology is used to recover the vinyl chloride in the condensate gas, investing more than 700,000 yuan, and recovering 1 ton of polyvinyl chloride monomer per day. The price of vinyl chloride monomer is 4,500 yuan/year. Tons, the entire investment can be recovered in 15 months and the benefits are substantial. As a result, PVC companies have attracted widespread attention and have invested in equipment to transform them.
Up to now, more than 20 PVC enterprises have adopted membrane adsorption technology to successfully reform the recovery of vinyl chloride in the condensing tail gas of dozens of vinyl chloride and polyvinyl chloride units. Several companies have adopted pressure swing adsorption technology for recovery. The transformation was successful and more manufacturers signed a contract for a technological transformation project. The full implementation of these projects will greatly improve the environment for PVC production, increase the economic efficiency of enterprises, and promote the sustainable development of the industry.
