Used 150 STPD Carbon dioxide liquefaction plant including CO2 compression, purification and liquefaction units as well as ammonia refrigeration system. Designed by SALOF. Inlet CO2 feed gas contains 97.53% of CO2, 2.44% of H2O and 0.03% of N2, at pressure of 4.4 PSIG and temperature of 105 °F. A booster increases the gas stream pressure to 300 PSIG through 2-stage compression. After a series of filters and dryers, the gas is liquefied into beverage-grade liquid CO2 (99.99% purity). The plant is skid-mounted type. All the major process equipment is inside a building, maintained in good condition. Full technical documentation is available. Also available are two liquid CO2 storage tanks (700 tons).
