饱和蒸汽压及密度对照
饱和蒸汽温度密度对照表正式版
饱和蒸汽温度密度对照表正式版饱和蒸汽温度、密度对照表1个大气压=100kpa=0.1Mpa=1公斤（kgf/cm2）概念必须明确：露点温度是指：在一定压力下，气体被冷凝至出现第一滴液滴时的温度，称为该压力下该气体的露点温度。
露点温度在沸点温度左右，比沸点温度稍高一些，因为冷凝和气化正好是个相反的过程。
由于沸点温度是随压力的变化而变化的，所以想要知道露点温度，只要查出该压力下的沸点温度，就知道露点温度的大概范围了。
而为了防止蒸汽在变换炉内发生冷凝，出现液态水危害催化剂，所以变换炉进口的最低温度都控制在，该操作压力下水蒸气的露点温度以上30-----50℃，绝对不允许低于此指标。
也就是说，当操作压力定了，那么变换炉的进口温度也就定了。
