Carbon dioxide liquefaction and recovery: Optimization practice of a single adsorption drying system

Including refrigeration unit and evaporation condenser, after purification of the gas under a certain pressure can only be liquefied under specific temperature conditions, the refrigeration unit is to provide enough cold for the liquefaction of carbon dioxide, in the evaporation condenser refrigerant and carbon dioxide gas heat exchange, carbon dioxide down to a certain temperature (-25 ° C) and then become liquid, sent to the storage tank for storage, while the gas that has not been liquefied, such as N2, O2 are discharged from the condenser. Refrigeration unit by the German Bitzer (Bitzer) compressor and refrigeration system components, refrigeration unit work and gas compressor operating capacity should be relative to the PLC for chain control, freezer for the screw-type refrigeration compressor has an energy regulator, energy regulation and compressor frequency synchronization, compressor frequency is high, the proportion of large energy regulator increased. Non-condensable gas is not directly empty waste, but is used as a pneumatic instrumentation drive and adsorption tower, drying tower regeneration, thus reducing the gas loss of the entire system, improve the carbon dioxide recovery rate.
