LIQUID RECTIFICATION METHOD

摘要

FIELD: natural gas technology. SUBSTANCE: method can be applied on field and factory installations and consists in heating and stripping low-boiling components (fractions), condensing vapors, and feeding non-condensed top vapors into vacuum- generation system, heating and evaporation of liquid in column bottom being effected by recirculation of liquid through vacuum-generation system. Stripping gas (non-condensed top vapors) is brought into contact with bottom liquid in depression zone of vacuum-generation system. The latter system is formed by a liquid-annular or liquid-jet pump. EFFECT: reduced power consumption. 4 cl, 2 dwg
