FIELD: process engineering.
SUBSTANCE: invention relates to carbon dioxide separation from gas mix. Enriched absorbent is recovered by steam desorption in regeneration column wherein gas including, mainly, released carbon dioxide and steam, is bled from column top and separated to obtain carbon dioxide flow to be removed and condensed water to be recycled to regeneration column.Lean or recovered absorbent is bled from column bottom. Note here that gas bled from column top is compressed and cooled by heat exchange for heat recovery before separation into carbon dioxide and water.
EFFECT: reduced medium-temperature power consumption.
