The CO2 recovery unit process begins with the raw material gas, carbon dioxide, being pressurized by a booster fan before entering the washing tower. Once washed, the CO2 gas moves into the dechlorination tower, where any traces of chlorine are removed. The purified carbon dioxide then undergoes compression in the CO2 compressor before being cooled and separated from water in a water-cooling and separation stage.
The compressed and cooled CO2 gas then enters a series of dryer absorbers, where moisture is effectively removed to ensure a high-quality product. To optimize energy efficiency, the dried raw material gas passes through a reheating heat exchanger, recovering the cooling capacity before entering the liquefaction process.
In the liquefier, the compressed CO2 gas exchanges heat with Freon, causing the carbon dioxide to condense. The condensed CO2 then flows into the rectification tower, where it undergoes further purification. The purified carbon dioxide liquid collects at the bottom of the tower and is directed to the reboiler for heating.
After the reboiler, the heated CO2 liquid is subcooled by a cooler to achieve the desired temperature. Finally, the high-quality, purified, and subcooled carbon dioxide liquid is supplied to customers as the end product.
