High purity nitrogen liquid nitrogen of small air separation

How to prevent water entrainment of air cooling tower of air separation equipment?

The raw air is compressed to about 0.52Mpa by the air compressor after filtering out dust and impurities, and then cooled to about 10℃ by the refrigerant glycol aqueous solution or Freon, and then enters the purification system to purify and remove water, carbon dioxide and other impurities in the air. Part of the raw material air enters the lower tower via the second raw material air pipeline, another part is liquefied into liquid air via the liquefier and enters the lower tower via the liquid ...
