Wet Scrubber System | Research Project Database | Grantee ...

In addition, the availability of a wet scrubber system will allow novel methods aimed at enhancing mercury removal in a FGD system to be tested. The goal of the proposed project is to develop a further understanding of the potential to capture toxic trace metal species by wet-scrubbing the flue gas generated by the combustion of selected coals.
