SYSTEM AND METHOD FOR TRANSFERRING LIQUID CARBON DIOXIDE FROM A HIGH PRESSURE STORAGE TANK TO A LOWER PRESSURE TRANSPORTABLE TANK

摘要

Both a system and method are provided for transferring liquid carbon dioxide from a storage tank pressurized at 300 psi to a truck-transportable tank pressurized at about 110 psi. The system includes an inlet conduit having a hose portion connected between the storage and transportable tanks for conducting a flow of liquid carbon dioxide therebetween, and a vent hose connected to the transportable tank for venting gaseous carbon dioxide. Pressure regulators are connected to the inlet and vent hoses, respectively. Automatic shut-off and purging mechanisms are provided. A muffler is connected to the outlet of the vent hose.
