FIELD: process engineering.
SUBSTANCE: invention relates to cleaning of fluids and can be used at absorption or desorption column. Device comprises mass exchanger containing volatile fluid and poor-volatile fluid. Mass exchanger includes structure bed. The latter includes first layer (10) and second layer (100). Bed first layer (10) contacts with second bed (100) via spacing elements (24, 34, 44, 134, 144). The latter make the component of the bed first or second layer (10, 100) and are composed of bridges. Said elements (33, 43, 133, 143) confine open channels 12, 14, 16, 112, 114, 116. First bed layer (10) and second layer (100) feature wavy profile making said open channels (12, 14, 16, 112, 114, 116). Method of cleaning includes the feed of poor-volatile fluid into mass exchanger and its distribution over common surface. Beside said process comprises the feed of volatile fluid into mass exchanger and its distribution at gas inlet over the common surface. Volatile fluid flows in counter stream with fluid. Then, volatile fluid is collected at the bed fluid exit. Open channels of the bed first layer cross the second layer channels of the bed. Volatile fluid flows in said channels from fluid inlet to outlet. Poor-volatile fluid envelops volatile fluid to flow in the walls of channels. Therefore, mass exchange is increased between volatile and poor-volatile fluids via mass exchange surface composed by said channels.
EFFECT: decreased drop in head, higher separation capacity of structured bed.
