Control of alkali vapors by a granular-bed filter
Control of alkali vapors in the pressurized fluidized-bed combustion (PFBC) of coal is being studied in a laboratory-scale fixed granular-bed filter. The potential sorbents identified earlier were tested for their alkali vapor sorption in a gas stream with temperature (greater than or equal to 850/sup 0/C), pressure (10 atm absolute), and composition closely simulating actual PFBC flue gas. The NaCl-vapor sorption efficiency of activated bauxite is > 99.8% and was found not to be diminished by HCl in flue gas. Diatomaceous earth has lower sorption efficiencies than activated bauxite. Emathlite, a fuller's earth, has a capability for NaCl-vapor capture. Its sorption behavior and preliminary sorption efficiencies are presented and discussed.
