【摘要】 聚氯乙烯生产是由连续过程和间歇过程合成的混合系统。本文依据聚氯乙烯生产过程的特殊性,基于物料平衡和时间平衡,建立了一类混合系统的数学模型,给出了它的时间序列优化控制,比较真实地反映了保证车间生产连续性、平稳性的利润最大的聚合釜开动台数的时序安排。更多还原

【Abstract】 Based on material and time balances the mathematic model for a kind of mixing system is dev elop ed, wich considers the speciality of a PVC production process, and the optimizing control of time sequence is given, too. This design reflects the real situation of time sequence, which sets the polymerizing reactors in motion, guaranteeing production continuity, smoothness and steadiness, and high profits.更多还原
