PLANT FOR PRODUCTION OF PETROLEUM POLYMER RESIN BY THERMAL POLYMERIZATION Russian patent published in 1994 - IPC

FIELD: plants for production of petroleum polymer resins. SUBSTANCE: plant has horizontal and successively connected polymerization reactors, fractionating towers for distillation of reaction byproducts, pipeline system and means for heating raw materials, and additionally has units for heat utilization according to number of reactors. Utilization units of polymerization heat consists of circulating heat exchanger, pump and pipelines for taking and returning polymerizate. Reactor has partitions installed square to longitudinal axis and forming labyrinth. Adjacent partitions are located on opposite sides of reactor and their length amounts to 2/3 of apparatus height. Depth of dipping of branch pipe for discharge of polymerizate from preceding reactor to subsequent reactor or fractionating tower is not less than height of partition installed on the side of same branch pipe. EFFECT: higher efficiency. 2 dwg
