CRYOGENIC SEPARATION PROCESS

Cryogenic Separation Process is also called Low-Temperature Rectification (<-40℃) Method. Substantially, it is a technology of gas liquefaction, the Process adopts Throttling Expansion Method or Adiabatic Expansion Method to compress and refrigerate gases in order to separate the gases by rectifying components at their various boiling temperatures. Cryogenic Separation Process is currently applied for Air Separating, Steel-Making, Natural Gas Liquefying & Separating, Modernized Coal Chemical industries, and it is one of the most common methods for air separation (the other two are Pressure Swing Adsorption & Membrane Separation).
