  • Process for the recovery of alkanolamines from their heat-stable salts formed in alkanolamine sorbent solutions
    Patent number: 4814051
    Abstract: There is described a simple two compartment electrochemical cell which may be associated in multiples in parallel for electrochemically freeing alkanolamines of the heat stable salt forming anions found or formed in acid gas conditioning thermal regenerative sorbent processes using alkanolamines as sorbents for acid gases, the cell having an anion exchange membrane separating the cell into two compartments and an anode comprised of an iridium coated electroconductive metal electrode.
    Type: Grant
    Filed: January 29, 1988
    Date of Patent: March 21, 1989
    Assignee: The Dow Chemical Company
    Inventors: Stephen A. Bedell, Susan S. Kuan Tsai
  • Process for the recovery of alkanolamines from their heat-stable salts formed during absorbent thermal regenerative step of gas conditioning processes
    Patent number: 4808284
    Abstract: There is described a simple two compartment electrochemical cell which may be associated in multiples in parallel for electrochemically freeing alkanolamines of the heat stable salt forming anions found or formed in acid gas conditioning thermal regenerative sorbent processes using alkanolamines as sorbents for acid gases, the cell having an anion exchange membrane separating the cell into two compartments and an anode comprised of platinum or a platinum coated electroconductive metal electrode.
