丙烯塔塔釜丙烯损失的工艺优化调整探究

Study on Process Optimization and Adjustment Aiming at Propylene Loss Problem in Propylene Tower Bottom

丙烯精馏塔的工艺调整作为乙烯装置的核心操作之一被广泛关注。通过优化操作、合理计算、精细管理,对精馏塔的主要工艺参数进行调整,使塔釜循环丙烷中丙烯损失降低至设计值以下,为工艺积累了丰富的操作数据,为装置实现了节能降耗目标。

The process adjustment of propylene rectification tower has obtained widespread attention as one of the core operations of ethylene plant. Through optimizing operation, reasonable computing and fine management, the main technical parameters of the rectifying column were adjusted to make the propylene loss reduce to less than design value; a lot of data for the process operation were accumulated.
