ABSTRACT:
The gas to be processed, flowing in through line10, contains impurities. This gas is contacted in column C1with a solvent flowing in through line18. The scrubbed gas is discharged through line19. The impurity-laden solvent recovered through line12is regenerated by expansion, then by distillation in column C2. The invention proposes carrying out expansion by means of two-phase turbines T1and T2.
