DEVICE FOR SEPARATE EXTRACTION OF COMPONENTS OF GAS MIXTURE Russian patent published in 2016 - IPC F25J3/00 F17C3/10 

FIELD: gas industry.

SUBSTANCE: present invention relates to technology of separate extraction of components of gas mixtures, particularly cleaning fluorine-containing gas mixtures from uranium hexafluoride and hydrogen fluoride, and can be used to improve quality and reduce the costs of gas-separation processes. Device for separate extraction of components comprises a cylindrical vessel with heat insulation with a detachable cover, wherein the side surface of the cylindrical vessel has branch pipes for circulation of a gaseous coolant: at the top - for coolant output, at the bottom-for coolant inlet. Inner surface of the cylindrical vessel is equipped with a gaseous coolant flow guide in the form of a rib arranged along the helical generatrix.

EFFECT: use of the invention provides the required degree of purification, considerably simplifies the design and servicing of cleaning plant as compared to the use of liquid nitrogen, provides almost complete elimination of manual labour, excludes hazardous factors during production that exist of using liquid nitrogen.
