摘要：
The fumes flowing in through line 1 are contacted in column C1 with a solvent, at low vapour pressure, absorbing the carbon dioxide. The solvent laden with carbon dioxide is regenerated by distillation in column C2. In order to improve the regeneration operation, a gas is injected through line 11 into column C2 so that this gas carries along the carbon dioxide contained in the solvent. The carbon dioxide-rich gaseous effluent obtained at the top of column C2 can be liquefied by compression and cooling, then stored in surge tank R, which allows its transportation and possibly underground sequestration.
