Babban kayan aiki na tsari shine MZCR (Multi zone zagayawa reactor tsarin) Reactor R230 tsarin. The reactor kunshi riser da downcomer. A cikin mai tashi, ana hura polymer zuwa sama ta hanyar iskar gas don samar da ruwa, which is sent to the upper part of the downcomer to pass through the cyclone separator, and the powder is collected in the downcomer. The reaction gas is circulated by the centrifugal compressor through the external pipeline, and the reaction heat is removed by the circulator cooler on the external circulation pipeline. The reactor product is discharged through a valve installed at the lower part of the downcomer. After degassing under high and low pressure, the discharged powder is evaporated and dried directly when homopolymer and random copolymer are produced. During the production of impact resistant products, the powder after high-pressure degassing is discharged into the gas-phase fluidized bed reactor. This reactor still adopts Spheripol II gas-phase reactor system. The copolymerization reactor is a vertical cylindrical vessel, with spherical head at the top and bottom, boiling bed at the bottom, stainless steel as the main material and polished inner surface.
