摘要： An integrated control system for a vinyl acetate process. A desired production rate of vinyl acetate is achieved by maintaining a desired reactor temperature. At the same time, the concentration of oxygen in the vinyl acetate reactor and condenser are maximized and the reactor pressure is maximized, all in a safe manner, so as to increase the selectivity of the process to the production of vinyl acetate. Also, the overall process is controlled so as to improve the efficiency of energy and materials usage.

摘要： An olefin polymerization process and apparatus wherein a fluid slurry comprising monomer, diluent and catalyst is circulated in a continuous loop reactor by two or more pumps. The process and apparatus allow operating the reaction at significantly higher solids content in the circulating fluid slurry. In a preferred embodiment, the fluid slurry is circulated by two impellers arranged so that the downstream impeller benefits from the rotational energy imparted by the upstream impeller. An olefin polymerization process operating at higher reactor solids by virtue of more aggressive circulation has improved efficiencies, particularly in larger-volume reactors.
