DEVICE OF GASSES DRYING BY FREEZING-OUT Russian patent published in 2005 - IPC

FIELD: gas-production industry and petrochemical industry.

SUBSTANCE: the invention presents a device for drying of gases by freezing-out and is dealt with the field of gasses drying devices. The device includes a vortex pipe, pipelines with the fixture, freezing out heat exchangers, a gas-distributing device mounted with a capability to feed either cool, or a hot gas from the vortex pipe into coiled pipes of heat exchangers. At that the inter-pipe space of the heat exchangers is connected with a pipeline of the humid gas delivery and a pipeline of the dried gas withdrawal. The vortex pipe is connected with a pipeline of the dried gas withdrawal and the coiled pipes outlet is connected with the pipeline of the dried gas withdrawal through an ejector. The device in addition has a pipeline connecting the pipeline of the humid gas reception through an adsorber with the pipeline of the dried gas withdrawal. The lower parts of the heat exchangers are used in the capacity of water-oil separators. The invention ensures an increase of efficiency and reliability of the device operation.

EFFECT: the invention ensures increased efficiency and reliability of the device operation.
