ABSTRACT:
A method and arrangement for facilitating removal of hydrogen sulfide from a combuation process gas includes provision of a packed bed scrubber having packing material therein comprising a polymeric substance having an outer surface with a substantially hydrophilic character. For preferred arrangements and methods, the packing material comprises a polymeric substance having a plurality of sulfonic acid groups, or neutralized sulfonic acid groups, thereon. A method of providing such packing material comprises reaction of a substantially hydrophobic packing material with sulfur trioxide. Preferred scrubber arrangements utilizing segmented packing beds are also disclosed. The result of the described methods and processes is a scrubber arrangement having a substantially reduced propensity for plugging, by comparison to conventional scrubber arrangements, when utilized for otherwise conventional scrubbing processes.
