Investments in all-liquid air separation unit: The difference between gas air separation and liquid air separation is whether the product from the cold box is gaseous or liquid, and the product from the cold box is gaseous, called gaseous air separation; the product from the cold box is liquid, called liquid air separation.Liquid air separation is divided into a group of heat exchangers (condensers) with gaseous air separation. After the product comes out of the purifier tower, it exchanges heat with a medium (dirty nitrogen), recovers the cooling capacity and further liquefies it.
