Abstract: A process for removing sulfur from a gas containing sulfur compounds as H2S, SO2, COS, CS2 . . . , in a quantity of up to 15% wt; particularly gases emanating from the Claus process: A first hydrogenation of the sulfur compounds into H2S, the hydrogenation gas being used to regenerate a deactivated bed of oxidation catalyst, both being carried out at 200-500° C. After sulfur removal, the resulting gas undergoes a second hydrogenation step and then a direct oxidation step, said step being operated under the dew point of sulfur to trap the formed sulfur in the catalyst. In the further cycle, the gas streams are switched so as to regenerate the catalyst in run which is deactivated.

Abstract: The invention concerns a flexible process for purifying a solvent which inhibits the formation of hydrates during gas processing, in particular monoethylene glycol (MEG), said solvent having a boiling point which is higher than that of water and, at least at one point in time, being mixed with water and salts, the process operating in a different manner with the same facility as a function of the quantity of salts in the MEG to be treated.The process operates in accordance with a phase known as reclaiming (separation of salts under vacuum followed by vacuum distillation) when the salts content exceeds the precipitation threshold and if not, the process operates in a regeneration phase (absence of separation of salts and no operation under vacuum).Advantageously, the change is made under the control of means for testing the salts.
