摘要
研究了浆液浓度、聚合釜撤热能力等对高密度聚乙烯装置生产能力的影响。结果表明:提高浆液浓度、延长停留时间保证乙烯转化率来提高聚合釜的负荷,同时,提高釜顶冷凝器和聚合釜夹套的热处理能力及循环气风机进釜风量,可提高装置生产能力。按目前实际生产中单釜最大负荷提高1.08倍计,生产能力可提高3.7%～7.4%。
The author studied the effects of slurry concentration and heat withdrawal capability on capacity of the polymerization reactor for high density polyethylene. The results show that the production load of the reactor can be improved by increasing slurry concentration and by extending residence time for ensuring ethylene conversion. On the other hand, the capacity of the reactor also can be augmented by enhancing heat withdrawal capability of top condenser and jacket of the reactor and by raising recycle gas quantity into the reactor through air blower. The capacity of a single reactor can rise by 3.7%-7.4%, calculated on the basis of 1.08 times of the largest load in the current practical production.
