LIQUEFYING OF NATURAL GAS IN MOVING ENVIRONMENT Russian patent published in 2017 - IPC F25J1/02 F25B41/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a process for liquefying natural gas in the floating liquefaction installation. The method comprises: a) introducing a cooling agent in the separation vessel (42) to form the stream (6) of vapor cooling agent and stream (8) of liquid cooling agent; b) introducing a flow (8) of liquid cooling agent around the lower part situated externally with respect to the separation vessel (42) of the core (50) of the heat exchanger; c) introducing the warmer process stream (12) into the externally located core (50) of the heat exchanger above the stream (8) of liquid cooling agent; d) cooling of warmer process stream (12) through indirect heat exchange with the liquid cooling agent stream (8) in the externally located core (50) of the heat exchanger to form a cooled process stream (14) and stream (16) of partially vaporized cooling agent; e) removal of cooled process stream and stream of partially vaporized cooling agent from the externally located core (50) of the heat exchanger. The separating vessel (42) has movement damping baffles.

EFFECT: invention improves efficiency of natural gas liquefaction in the floating installation.
