REGULAR ADAPTER FOR HEAT-AND-MASS EXCHANGE APPARATUSES Russian patent published in 2014 - IPC B01J19/32 

FIELD: process engineering.

SUBSTANCE: invention relates to regular nozzles for heat-and-mass transfer process in gas (steam)-fluid system, e.g. rectification, absorption cleaning and drying of natural gas. Besides it can be used in chemical, oil-and-gas industries, etc. Said nozzle consists of stacked horizontal element formed from ceramic or plastic materials. Nozzle elements feature curvilinear surface consisting of regular conical ledges and recesses. Note jeer that round through holes are made at ledge top and recess bottom. Said ledges and recesses are staggered so that one ledge is surrounded by four recesses. Walls of said ledges and recesses are either polyhedral (eight faces). Horizontal elements are laid one onto another and jointed together so that holes at adjacent ledge holes overlap to make vertical variable-cross-section gas and fluid passages.

EFFECT: efficient operation, intensive heat-and-mass transfer.
