Claims

A system for cooling or liquefying process gas in a moving environment,
a. A separation vessel, wherein the separation vessel separates the refrigerant stream and thereby generates a gaseous refrigerant stream and a liquid refrigerant stream;
b. A gas-liquid refrigerant pipe for delivering the liquid refrigerant stream from the separation vessel to an external heat exchanger core;
c. At least one external heat exchanger core, wherein the liquid refrigerant stream and warmer process stream undergo indirect heat exchange in the external heat exchanger core, thereby reducing the cooled process stream and the vaporized refrigerant stream. Generate
d. A partially vaporized refrigerant pipe for delivering the partially vaporized refrigerant from the external heat exchanger core to the separation vessel;
Including the system.

The system of claim 1 , wherein the refrigerant stream is delivered to the separation vessel as a high pressure liquid refrigerant.

The system of claim 1 , wherein the separation vessel includes a plurality of motion restraining baffles.

The system of claim 3 , wherein the plurality of motion suppression baffles are arranged horizontally, arranged vertically, or arranged horizontally and vertically .

The system of claim 1 , wherein the partially vaporized refrigerant pipe provides a minimum pressure drop.

The system of claim 1 , wherein the partially vaporized refrigerant pipe ensures that the thermosyphon effect is maintained.

The system of claim 1 , wherein the cooled process stream is delivered to a location external to the external heat exchanger core.

The process of claim 1, wherein the external heat exchanger core is external to a kettle.

A method for liquefying natural gas in a moving environment,
a. Introducing refrigeration into the separation vessel, thereby producing a gas refrigerant stream and a liquid refrigerant stream;
b. Introducing the liquid refrigerant stream near the bottom of the external heat exchanger core;
c. Introducing a warmer process stream into the external heat exchanger core at a position above the liquid refrigerant stream;
d. Cooling the warmer process stream by indirect heat exchange with the liquid refrigerant stream in the external heat exchanger core, thereby producing a cooled process stream and a partially vaporized refrigerant stream;
e. Removing the cooled process stream and the partially vaporized refrigerant stream from the external heat exchanger;
