Abstract
A method and apparatus for removing sulfur from gas streams, utilizing liquid redox, including an improved method for preventing build-up of elemental sulfur in a sulfur absorber. Ultrasonic irradiation of one or more portions of the structure of the absorber prevents sulfur build-up. In combination with monitoring of the pressure across the absorber, the freeing of sulfur from surfaces in an absorber can be automatically actuated.
