Use of a two-phase turbine in a gas treating process

摘要

The gas to be processed, flowing in through line 10 , contains impurities. This gas is contacted in column C 1 with a solvent flowing in through line 18 . The scrubbed gas is discharged through line 19 . The impurity-laden solvent recovered through line 12 is regenerated by expansion, then by distillation in column C 2 . The invention proposes carrying out expansion by means of two-phase turbines T 1 and T 2.
