Title: The Innovations of William D. Clarke
Introduction
William D. Clarke is a notable inventor based in Brazoria, Texas, recognized for his contributions to the chemical manufacturing industry. He holds a total of 3 patents, showcasing his innovative approaches to producing vinyl chloride monomer from ethane and ethylene.
Latest Patents
Clarke's latest patents include a process for vinyl chloride manufacture from ethane and ethylene with partial hydrogen chloride recovery from reactor effluent. This process involves significant quantities of both ethane and ethylene in the input streams to the reactor. The hydrogen chloride in the reactor effluent is only partially recovered in the first unit operation after the ethane/ethylene-to-vinyl reaction step. The steps presented include oxydehydro-chlorination catalytic reaction of ethane, ethylene, hydrogen chloride, oxygen, and chlorine, cooling and condensing the reactor effluent stream, and separating the condensed raw product stream into vinyl chloride monomer and a reactor recycle stream.
Another significant patent by Clarke is for a process for vinyl chloride manufacture from ethane and ethylene with immediate hydrogen chloride recovery from reactor effluent. In this process, significant quantities of both ethane and ethylene are used in the input streams to the reactor. The hydrogen chloride in the reactor effluent is essentially fully recovered in the first unit operation after the ethane/ethylene-to-vinyl reaction step. The steps include oxydehydro-chlorination catalytic reaction, quenching the reactor effluent stream to provide a raw product stream with essentially no hydrogen chloride, and separating the raw product stream into a vinyl chloride monomer product stream and a lights stream, with recycling of the lights stream to the reactor.
