["El gas气分各塔顶热旁路控制投用吗？我们直接把热旁路手阀关闭，冷路全开。","¿ElEl气分各塔顶热旁路控制投投吗？我们直接把热旁路手阀关闭，冷路全开。","""这个有很多因素除根据你的负荷、塔顶换热介质的温度、塔压包括设备换热效果。我们不怎么用热旁路一般用换热介质的流速来控制塔顶压力相对平稳。一般冬天负荷小的时候进料组分变重的时候我们会用热旁路来维持平衡。","""Nos我们这边脱丙烷塔丙烯精馏塔顶都设计有热旁路但是我们没怎么用过原先投投的时候操作不稳定感觉调节阀调节之后造成塔底液位忽涨忽降感觉不如卡脖子式好操作可能跟介质或者操作压力、冷却负荷有关系我们催化这边稳定塔用起来比较平稳。"","""¡我们这边脱丙烷塔丙烯精馏塔顶都设计有热旁路但是我们没怎么用过原先投用的时候操作不稳定感觉调节阀调节之后造成塔底液位忽涨忽降感觉不如卡脖子式好操作可能跟介质或者操作压力、冷却负荷有关系我们催化这边稳定塔用起来比较平稳。"","用的很好啊！调节可能太猛了！缓慢！冬天冷后温度低了！不节能啊""]
