METHOD FOR SEPARATION OF BINARY OR MULTICOMPONENT MIXTURES OF LIQUID-VAPOR SYSTEM

摘要

FIELD: petrochemical industry. SUBSTANCE: method involves carrying out separation in rectification column by supplying raw material in periodic cycles in countercurrent with respect to vapor flow with maximum flow rate of 110-150% minimum flow rate of 50-90% by weight of design flow rate and cycle period of 60-200 sec; extracting stillage residue and distillate; feeding reflux for column spraying by periodic cycles with maximum flow rate of 84.3-110% minimum flow rate of 31.3-63.04% by weight of design flow rate of reflux and cycle period of 60-100 sec. Flow rate of heating steam for boiling device is reduced by 6-18% EFFECT: reduced power consumption and high quality of main product. 1 dwg, 10 tbl
