The overall goal of this Energy & Environmental Research Center project was to evaluate water capture technologies in a carbon capture and sequestration system and perform a complete systems analysis of the process to determine potential water minimization opportunities within the entire system. To achieve that goal, a pilot-scale liquid desiccant dehumidification system (LDDS) was fabricated and tested in conjunction with a coal-fired combustion test furnace outfitted with CO{sub 2} mitigation technologies, including the options of oxy-fired operation and postcombustion CO{sub 2} capture using an amine scrubber. The process gas stream for these tests was a coal-derived flue gas that had undergone conventional pollutant control (particulates, SO{sub 2}) and CO{sub 2} capture with an amine-based scrubber. The water balance data from the pilot-scale tests show that the packed-bed absorber design was very effective at capturing moisture down to levels that approach equilibrium conditions
