This contract provides for laboratory experiments and analyses to develop electrostatic granular bed filtration for Pressurized Fluidized Bed (PFB) combined cycle application. These experiments will provide the data necessary to design a hot test model and to perform systems integration and economic evaluation studies. Based on the laboratory results, preliminary engineering estimates of the capital and operating costs will be provided for the selected approach. Progress on this work is reported. In parallel with the electrostatic granular bed filter testing, laboratory scale experiments and engineering assessments will be performed for two concepts for removing corrosive alkali metal vapor from the combustion gases. The work on adsorption of NaCl on bauxite has led to two important conclusions: (1) the adsorption of NaCl on activated bauxite follows the BET isotherm; and (2) significant adsorption, greater than a half of monolayer coverage, can be achieved at very low alkali levels in gas, comparable to those desired in the PFB gas entering the gas turbine.
