METHOD OF WET NATURAL GAS COOLING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC F28D1/04 F25J3/08 

FIELD: machine building.

SUBSTANCE: inventions can be used in air-cooled devices (further - ACD), where during operation in conditions of cold climate of northern regions the gas hydrates can be formed. Tube banks are made with the slope minimum 1:100 upstream, and under the lower row of pipes gas bare bypass pipes fixed from the one side in the lower zone of the input camera, from the other side affixed to the pipes of gas extraction, are located with the slope towards downstream. Gas is conveyed by the cooled pipe bank with the rise downstream, with the beginning of thaw of formed hydrate plugs free draining of the melted water from hydrated pipes to the lower zone of the input camera is organised, and it is further conveyed by bare bypass pipes with the slope towards the pipe for extraction of the cooled gas.

EFFECT: achieving of the cooled gas temperature is lower than the temperature of hydrate forming start, prevention of cracking at the surface of heat exchanging tubes and avoidance of their disruption at the expense of removal of hydrate plugs.
