After the air compressor compressed and pre-cooled air, and then by the purification system to remove water, carbon dioxide and other harmful impurities, into the main heat exchanger cooling part directly into the lower part of the distillation tower. Another part of the liquefier in the liquefied also into the lower tower of liquid air separation plant, in the lower tower in the initial distillation, in turn to obtain high purity nitrogen with liquid nitrogen, dirty liquid nitrogen, poor liquid...
Given the high sensitivity of oxygen piping to combustibles, piping cleanliness of small air separation unit is an important part of quality control for oxygen piping installations and is subject to the most rigorous degreasing, cleaning and drying treatments. The interior of the pipework should be free from the accumulation of moisture, cleaning agents, particles, organic oils, grease and adhesives, paint and record pen marks and other debris etc.
If there is metal debris or grit in the pipe, ...
