METHOD OF LOW-TEMPERATURE SEPARATION OF AIR AND DEVICE FOR SEPARATION OF AIR Russian patent published in 1998 - IPC

Abstract RU 2107871 C1

FIELD: separation of air. SUBSTANCE: cleaned and cooled air is directed to distillation system containing at least one fractionating tower where it is rectified through counter-flow mass transfer between vapor and liquid phases. Mass transfer at least in one zone of at least one fractionating tower (3,5,15) is effected by means of checker having specific surface of at least 1000 sq. m/cu.m. EFFECT: enhanced efficiency of separation. 24 cl, 4 dwg , 1 tbl
