Abstract: A method for separating benzene, toluene, xylenes and higher aromatics from admixtures containing them is disclosed, said method being based on the use of a solvent which is a 5-atom cyclic derivative of urea in which at least one of the nitrogen atoms is bound to an alkyl. Representative of this class of selective solvents is N,N'-dimethyl ethylene urea. Procedure details and examples are given.

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 CO2-laden solvent to the desulfurization stage.
