FIELD: mass-transfer apparatuses for processes of rectification, may be used in alcohol and petrochemical industries. SUBSTANCE: apparatus has separately installed sections consisting of separators and coaxially installed cylindrical sleeves connected with separators by vapor-liquid ejectors, vapor and liquid branch pipes. Attached to internal side surfaces of separators and outer surfaces of sleeves are flow deflectors.
