GAS LIQUIDATION SYSTEM Russian patent published in 2021 - IPC F25J1/02 F28C3/08 F17C3/00 

FIELD: refrigeration and cryogenic technology.

SUBSTANCE: gas liquefaction system refers to refrigeration and cryogenic technology and is designed to liquefy evaporated components, for example, fuels in land-based power plants and vehicles. The heat exchanger is made in the form of a cryogenic vessel with a collector located in its lower part of the liquid volume; a liquefied gas supply pipeline with a shut-off valve and a pressure regulator is connected to the collector. Pipelines are connected with the lower part of the cryogenic vessel through valves for supplying liquid refrigerant and removing liquefied gas. The gas cavity of the cryogenic vessel is connected to a refrigerant vapor outlet pipe in which a drain valve is installed. The collector contains capillary channels for the release of the liquefied gas in the form of bubbles into the liquid refrigerant, while the capillary channels are located on the collector in such a way that the trajectories of the bubbles emerging from different capillary channels upward through the layers of the liquid coolant do not coincide.

EFFECT: increasing the efficiency of the gas liquefaction process and improving the economy due to the fact that the bubbles coming out of different capillary channels do not mix, completely condense and do not reach the gas cavity of the cryogenic vessel.
