ABSTRACT:
A method is disclosed for removing acidic gaseous components from natural gases, this method comprising an initial desulfurization stage employing a selective solvent, then removing carbon dioxide by low temperature distillation, the carbon dioxide providing the cooling effect required for such a condensation, recovering the solvent, absorbing the residual carbon dioxide with the regenerated solvent and recycling the CO.sub.2 -laden solvent to the desulfurization stage.
