The Synthesis Of PVC Resin Hydrogen Chloride And Tail Gas Recovery Process Optimization

The method of producing PVC resin by using calcium carbide is widely used inour country. In the process, Hydrogen chloride process and Exhaust gas adsorptionprocess are the necessary parts.In the case of rapid development in science andtechnology, because of the early foundation and the backward technology, ourcompany can not satisfy the requirements of production and the rules ofenvironmental protection. Therefore, we need to transform to meet the currentdemand.This paper states the developing process of polyvinyl chloride (PVC) and thecurrent condition together with the production methods, formula, equipment and rawmaterials of the Polyvinyl chloride (PVC) resin. It introduces the properties andpreparation methods of hydrogen chloride and the components of rectification tail gas.It introduces the scheme, process and result which are related to the Hydrogenchloride synthesis processes and optimization and modification of the distillation oftail gas adsorption process,It is proved in the practical industrial operation that the technology can reduceenergy consumption after the transform. The technology can Improve the productioncapacity and has reached the state environmental protection requirements and thedesired effect...
