MASS-TRANSFER PROCESS COLUMN Russian patent published in 2000 - IPC

FIELD: gas-extraction, oil- refining, and petrochemical industries. SUBSTANCE: column has body with gas and liquid inlet and outlet pipe unions, vertical mass-transfer and separation extension pipes mounted between horizontal barriers in a spaced relation to body. Inertial pre-separator is arranged along column axis with primary separator, mass-transfer section, and final separator mounted in tandem around it. Top of inertial separator is connected to gas inlet pipe union, that of mass-transfer section is connected through gas- tight joint to pipe union feeding liquid to column; bottoms of inertial and primary separators are connected to separated-liquid collector and those of mass-transfer section and final separator are joined to entrainment separator. Inertial pre-separator whose wall is made of louver strips bent over external surface to face gas flow accommodates hollow conical displacer whose bottom part is connected to separated liquid collector and top one has injection ducts. EFFECT: improved mass-transfer efficiency due to reasonable utilization of column interior. 2 cl, 2 dwg
