CO2 Purification and Liquifying Plant Union Engineering RBU 1500 kg

Gaseous carbon dioxide (CO2) is fed from the fermentation process through the foam separator where fermentation foam is removed and gas is pumped to the intermediate 50 m3 CO2 buffer storage balloon (NOTE: Foam separator is not included in this equipment) From this intermediate storage gas is fed into the scrubber where  designed to clean the CO2 from ethanol and other impurities are washed away with a clean water flow in counter current scrubber.

Ethanol free CO2 gas is fed into intercooled piston type CO2 compressor where it is compressed in two stages into 18.5 bar. Compressed gas (CO2) is led in to purification unit where it passes through double acting, electric heated cleaning and drying filters. These filters are removing odor causing components and draining of CO2, which is then fed to the liquefaction plant. Liquefaction plant consist a condenser, stripping drum, evaporator and chiller running on R507 refrigerant. Refrigerant is compressed with a screw cooling compressor and it evaporates in the condenser and cools CO2 at - 30 0 C, allowing the condensation of CO2 at a pressure of 17.4 bar. Non-condensable gases will be extracted from liquid CO2 in this stage. Clean, liquefied carbon dioxide is pumped into the storage tank.
