In recent years, the global greenhouse effect has intensified, the climate environment has deteriorated, and extreme weather has increased, resulting in a large number of climate migration and crop losses. CO2 is the main greenhouse gas. Based on this background, this technology comprehensively recycles CO2 gas, which increases economic benefits while at the same time. Reduce CO2 emissions.
The slightly positive pressure feed gas containing saturated water is firstly conveyed to the pre-cooler through the Roots blower to cool down to 3~5℃, and then the 3/23 filter separator is used to remove the liquid water and impurities; the gas after preliminary dehydration enters the feed gas After the compressor is pressurized to 2.3MPAG, it exchanges heat with the flash steam and then recovers the cold energy, and then enters the drying system for deep dehydration. The deeply dehydrated gas enters the evaporator of the refrigerator and exchanges heat with the refrigerant to -25°C to liquefy the liquid LCO2 through throttling and depressurization. The non-condensable gases (hydrogen, nitrogen, The pressure of the LCO2 product is about 1.6MPAG and the temperature is -28 °C. The LCO2 is transported from the product tanker to the storage or use site; the non-condensable gas released is discharged at a high point after recovering the cold energy.
