Troubleshooting of Deep Cold Air Separation Equipment

Liquid air separation plant liquid hub area piping arrangement is mainly oxygen, nitrogen, argon liquid pipeline and pump box in the liquid pipeline arrangement. As oxygen, nitrogen, argon liquid temperature is extremely low (liquid oxygen -183 ° C ℃, liquid nitrogen -196 ° C, argon liquid -185.7C), in the liquid flow process, resulting in a certain amount of gasification, piping should pay attention to the slope of the liquid pipeline towards (no slope requirements on the process). In ...

We calculate the number of plates assuming that the liquid and vapour on each plate are interacting to reach equilibrium. In practice, it is not possible to achieve an ideal equilibrium for all plates in a nitrogen distillation column, so the actual number of plates required is greater than the theoretical number of plates required. The ratio of the theoretical to the actual number of plates is the full tower efficiency. Factors affecting the full tower efficiency are: the gas phase and liquid p...
