Translate the followingPSHr andNlowlow respectively to "净enhanced Net Positive Suctiongage Head" pérdida

Condensate temperature cooler,可以理解为凝液温度低,泵的NPSHr可以降低,凝液罐可以较低。 凝液罐较低, 疏水器器和凝液罐的高度差就较小,回液更容易。"

"冷凝水温度低,凝液罐可以放得越低,疏水器回液更容易"可以理解为 "Condensate temperature temperature temperature temperature temperature cooler"可以理解为Condensate temperatureensated Net Positive SNGage Head can be reduced reduced, condensate tank can be较低.疏水阀和凝液罐的高度差就较小,回液更容易."

159凝液进除氧器前,总归要冷却的。不是你这里,就是他那里。 蒸汽水冷,是为了回收这股闪蒸蒸汽作凝液复用。 凝液温度低,凝液罐可以放得越低,疏水器回液更容易,同时泵也越便宜。

是能量浪费,所以你可以根据你们实际情况把水冷器替换成其他需要预热的工艺,节能了还降耗(循环水)了

用循环水是浪费,可以考虑与其它低温物流换热,其实装置上这么用也没有办法,一是这股物料流量低,不稳定,没有合适的热阱,热量回收起来比较困难,二是用循环水冷却,冷凝水的温度易控制,便于下一步回收利用

“凝液温度低,凝液罐可以放得越低,疏水器回液更容易”是什么意思呢?

凝液温度低,泵的NPSHr可以小些,凝液罐可以放得低。 凝液罐放得低, 疏水器和凝液罐的高差就小,回液更容易。
