GAS LIQUEFACTION UNIT Russian patent published in 1998 - IPC

FIELD: cryogenics. SUBSTANCE: the design of the turbulent coolers and their connections are altered with a coaxial arrangement in the unit power body; the upper cooler provides for separation and discharge of fluid with an effective cooling of the heat exchanger, preventing the escape of drips. Due to installation of a turbulent ejector at the outlet of the non-liquefied part of the flow, complete utilization of cryostat vapors is ensured for cooling the inlet flow, which makes it possible on the whole to liquefy up to 25% of the inlet flow at a pressure of 6.0 MPa at a backpressure of the non-liquefied part equal to 0.6 MPa. Units of any capacity may be produced by a set of such modular connection units of turbulent coolers in one power body. EFFECT: improved design. 2 dwg
