DEVICE FOR COOLING NATURAL GAS Russian patent published in 2004 - IPC

FIELD: gas industry.

SUBSTANCE: piping sections for gas are mounted inside the housing partially filled with a liquid whose boiling temperature at atmospheric pressure is less than that of the natural gas. Thermal siphons are built in the top part of the housing. The thermal siphons are mounted vertically and interconnected with ribs which form passages for air. The thermal siphons are enclosed by the casing provided with slide valves at the top part and openings for passing air at the bottom. The outer pipe of the thermal siphon is submerged into the liquid, the inner pipe passes through the side opening in the outer pipe at a level higher than that of the liquid in the housing. The device is provided with a unit for control of slide valves, which is connected with heat exchange sections and air temperature gauge through gas temperature and humidity pickups.

EFFECT: enhanced efficiency.
