Liquid Carbon Dioxide - LCO2

LIQUID CARBON DIOXIDE

The low-pressure liquid is an alternative method of storing CO2 and is produced either by expanding high-pressure CO2 to a lower pressure or by refrigeration. It is held in specially constructed storage tanks, heavily insulated and equipped with refrigeration units to hold the internal tank pressure at or below 21 bar (304,58 psi) and -18 °C (-0.4°F) temperature. Pressure switches are incorporated to control the refrigeration units and safety mechanisms and electrical alarms are fitted to release the tank pressure and raise an alarm in the event of refrigeration malfunction.
