Title: Innovations in Polyvinyl Chloride Production by Dongsheng Liu

Introduction

Dongsheng Liu is a prominent inventor based in Beijing, China. He has made significant contributions to the field of chemical engineering, particularly in the production of polyvinyl chloride (PVC). His innovative approach addresses environmental concerns while enhancing production efficiency.

Latest Patents

Dongsheng Liu holds a patent for a "Loop-route production method and system for polyvinyl chloride." This invention relates to a method that integrates coal chemicals, polymer materials, and chemical machinery. The process involves reacting limestone and carbon materials in an oxygen-enriched high-temperature furnace to produce calcium carbide and carbon monoxide. Subsequently, acetylene and carbon monoxide are generated from calcium carbide and dichloroethane. The end products are combined to form a closed-loop system, which ultimately leads to the production of vinyl chloride monomer that is polymerized to obtain polyvinyl chloride. This innovative system not only reduces dependence on oil resources but also eliminates mercury pollution during production.
