  • Process for reducing energy consumption in the regeneration of hybrid solvents
    Patent number: 11253811
    Abstract: Disclosed is a process for regenerating a hybrid solvent used to remove contaminants from a fluid stream and to provide an improved yield of purified fluid. Said process comprises at least one purification unit (12) and at least one regeneration unit (40) wherein condensed water 62 from the regeneration unit is recycled back into the purification unit and none of the condensed water is reintroduced into the regeneration unit.
    Type: Grant
    Filed: April 19, 2017
    Date of Patent: February 22, 2022
    Assignee: Dow Global Technologies LLC
    Inventors: John R. Dowdle, Christophe R. Laroche, Diego Ortiz Vega, Linda L. Pirtle
  • Energy efficient process for separating hydrogen sulfide from gaseous mixtures using a hybrid solvent mixture
    Patent number: 11167241
    Abstract: Disclosed is a process for regenerating a hybrid solvent used to remove contaminants from a fluid stream and to provide an improved yield of purified fluid. Said process comprises a purification unit (12) and at least one regeneration unit (40) wherein make-up water (72) is added to the regenerated lean hybrid solvent (55) prior to reuse in the first purification unit and no water is recycled into the regeneration unit.
    Type: Grant
