ABSTRACT:
The present invention provides a method for rejuvenating an aqueous alkanolamine solution being at least partially deactivated from contact with an acid gas, said rejuvenation method comprising contacting said aqueous alkanolamine solution with hydrogen in the presence of a hydrotreating catalyst under hydrotreating conversion conditions including contact time sufficient to increase the acid gas sorption capacity of said aqueous alkanolamine solution.
