ABSTRACT:
Systems, methods and apparatus for restricting scale build-up in gas scrubbers and piping are disclosed. The scrubbers and/or pipes may have a coating disposed on internal surfaces thereof. The coating restricts formation of scale within the pipe, especially scale that would normally accumulate due to fluoride-enriched absorbents, such as fluoride-enriched alumina.
