Troubleshooting of Deep Cold Air Separation Equipment

1. Before connecting the pipe orifice of each container, clean white cloth shall be used to tie the orifice to prevent grease and dirt from entering. 2. When welding in the cold box and in the condensing evaporator, it is strictly forbidden for flame or arc to touch the surface of vessels and pipes. 3. The containers, valves, pipes and corresponding supports in the cold box, the surface of the cold box and the foundation surface shall not be stained with grease after installation, otherwise, degreasing treatment shall be carried out.

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).
