PP-<strong>II</strong>-54PR<strong>OP</strong>YLENE POLYMERIZATION AND PR<strong>OP</strong>YLENE-ETHYLENECO-POLYMERIZATION REACTORS MODELINGReutova O.A., Gulyaev K.S., Timofeev G.S, Galyamov A.V., Demin A.M.Omsk State University of F.M. DostoevskyRussia, 644077 Omsk, Pr. Mira, 55а, reutova@univer.omsk.suThe technological scheme for propylene polymerization on Ziegler-Natta(the fourth generation) catalysts is considered. Reaction proceeds consistently infollowing reactor cascade: the pre-polymerization reactor (R200), two liquid-phasepolymerization reactors (R201 and R202), and the gas-phase reactor for propyleneand ethylene co-polymerization (R401).Computer model of consistently connected four reactors of conversion type hasbeen constructed in UniSim Honeywell platform (fig. 1). For maintenance ofdemanded temperatures and pressure it is calculated auxiliaries: the heatexchangers, the pumps, the compressor, the valves.S-1S-2S-3Fig. 1 Computer model for propylene polymerization reactors431
