METHOD OF OPERATION OF PROCESS FOR PREPARING COPOLYMERS OF ETHYLENE AND PROPYLENE Russian patent published in 2003 - IPC

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to the field of automation of technological processes in production of synthetic rubber and can be used in production of rubbers of type СКЭП and СКЭПТ in petrochemical industry. Method of operation of process for preparing copolymers of ethylene and propylene in hydrocarbon solvent medium on complex catalyst into reactor involves regulation of consumption of monomers, solvent, catalyst and co-catalyst, pressure, level of temperature in the upper and bottom part of reactor. Ethylene, propylene, hydrogen are fed to distributing collector and circulating gas is fed to circulation contour and prepared mixture is fed to bottom part of reactor. Catalyst and co-catalyst, the first and the second consumptions of solvent and the third monomer in preparing the triple co-polymer are fed to upper part of reactor under condition of the following required ratios: ethylene : propylene or ethylene : propylene: the third monomer in preparing triple co-polymer, catalyst : co-catalyst, the first and the second consumptions of solvent : monomers. Depending on the average temperature value into reactor feeding solvent into reactor or feeding cooling agent in reactor jacket is corrected. The prepared polymerization product is fed to degasifier-concentrator and depending on the required value of temperature in it the consumption of water or steam into jacket of degasifier-concentrator is corrected . EFFECT: expanded region of usage of operation method, enhanced quality of rubber prepared. 6 cl, 1 dwg, 2 tbl, 1 ex
