Title: Diwaker Singh: Innovator in Polymerization Processes
Introduction
Diwaker Singh is a notable inventor based in Singapore, SG. He has made significant contributions to the field of polymerization processes, holding a total of 4 patents. His innovative work focuses on improving the efficiency and effectiveness of gas-phase reactors used in polymer production.
Latest Patents
One of his latest patents involves a method for reducing the accumulation of C6+ hydrocarbon components in polyolefin gas-phase reactors. This polymerization process includes polymerizing a monomer with four or fewer carbons and a comonomer with six or more carbons in the presence of an inert isomer or saturate of the comonomer. The process yields a product stream that comprises a polymer, unreacted monomer, unreacted comonomer, and the inert isomer or saturate of the comonomer. The product stream is then separated into a polymer stream and an unreacted components stream. The unreacted components stream is further separated in a distillation column, ensuring that the concentration of C5− hydrocarbons in the overhead stream is higher than in the unreacted components stream, while the concentration of C6+ hydrocarbons in the bottoms stream is also higher than in the unreacted components stream.
Another significant patent focuses on optimizing inert gas partial pressure in gas-phase polymerization processes. This process involves contacting an input stream comprising a monomer and an induced condensing agent in the presence of an inert gas with a catalyst in a fluidized bed reactor. The method aims to produce a polymer and unreacted monomer while maintaining a partial pressure of the inert gas above a reference inert gas pressure. This optimization helps decrease losses of the recycle stream with the vented output gas.
