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

Carbon dioxide gas after the initial purification due to scrubbing treatment contains more water gas, must first pass through the liquid-gas separator to remove liquid moisture; and then into the compressor compression pressure rises to 1.8Mpa or so, carbon dioxide gas compression temperature is higher for 60-90 ℃ need to be cooled, the after-cooler using water-cooled way, you can put the high-temperature gas cooled to 40 ℃ or so; cooling compressed gas and a A large amount of liquid water precipitation out of the cooled compressed gas, so here also need to set up a liquid-gas separator to separate the water, before entering the adsorption drying system and the low-temperature carbon dioxide gas for heat exchange, the temperature of the compressed gas to further reduce the compressed gas, and then the compressed gas is then sent to the drying and liquefaction system, the liquid-gas separation are used to cyclone separation of the principle of removing the liquid and solids, the use of automatic sewage valve for automatic sewage. The working condition of the gas compressor is interlocked with the refrigeration unit and synchronized with the starting and stopping.
