BUTYL RUBBER PRODUCTION PROCESS CONTROL METHOD Russian patent published in 2003 - IPC

FIELD: rubber industry. SUBSTANCE: in order to increase accuracy in controlling condition parameters when preparing polymerization charge and when performing copolymerization of monomers, invention proposes regulation of monomers/solvent/catalyst ratio and also preliminary cooling of charge to temperature of copolymerization reaction, which improves temperature condition control and therefore homogeneity and quality of rubber. In addition, regulating parameters of stirrer drives taking into account structural features of reactors increases working period of the latter and increases productivity of rubber production plant. Method of control includes a complex of mutually related interventions, in particular isobutylene/isoprene ratio and isobutylene/isoprene/inert solvent ratio adjustments and regulation of partial derivative of polymer temperature in reactor as function of catalyst uptake, and others. EFFECT: increased productivity of process and improved quality of product. 1 dwg, 1 tbl
