Safety of cryogenic air separation equipment

The required steam pressure, flow rate, etc. should meet the process design requirements when the molecular sieve is heated. The heating regeneration process in small air separation unit can be judged by the regeneration temperature curve. In the unloading stage, the adsorption capacity of the molecular sieve decreases due to the pressure drop, and some of the water and carbon dioxide molecules originally adsorbed are desorbed, and the temperature drops. In the heating stage in small air ...

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 ...
