Description:
The report gives results of a study to: evaluate existing data on H2SO4 measurements from fluidized-bed combustion (FBC) processes; determine the true value of the H2SO4 concentration which might have been obtained had the control condensation (Goksoyr/Ross) procedure been used; and run a material compatibility study to find alloys that can be used to fabricate a controlled condensation sampling system. The sampling system at Exxon's FBC facility was reviewed: H2SO4 values are about 12% low with another reduction of 10-25% because of low sampling temperatures and Balstron filters. The control condensation system with an acid/base titration using bromophenol blue as the indicator is the recommended sampling/analysis method for H2SO4 sampling at the Exxon facility. Construction material for the controlled condensation system can be 316L stainless steel, which had the best performance when subjected to various tests used to simulate an FBC environment and will easily withstand the pressures found at the Exxon facility.
