  • Process for the dehydration of gases
    Patent number: 7998248
    Abstract: Process for the dehydration of gases, comprising: absorbing water vapor by means of a hygroscopic liquid consisting essentially of one or more C2-C8 glycols and an additive capable of forming a minimum type azeotrope with water; distilling the glycol/water/additive mixture to obtain a top product consisting mainly of the water/additive azeotropic mixture and a bottom product consisting mainly of glycol and additive (hygroscopic liquid); recycling the regenerated hygroscopic liquid to the absorption stage.
    Type: Grant
