Synthesis Gas Demonstration Plant Program, Phase I. Trade-off Studies Report IV, Air Quality Control Alternatives

摘要

For particulate removal systems four alternate methods were considered: wet venturi scrubbers, combination of multicyclonic mechanical dust collectors (MDC) and wet venturi scrubbers; electrostatic precipitators (ESP), and baghouses. For sulfur dioxide (SO sub 2 ) removal eleven alternate systems were considered: magnesia slurry scrubbing, sodium sulfite scrubbing (Wellman-Lord), ammonia (clear liquor), citrate, phosphate (Aqua-Claus), steam stripping, aqueous carbonate, ammonia (semi-dry), carbon sorption, copper oxide, and catalytic oxidation. On the basis of this investigation it is recommended that a 99.65 percent efficiency ESP/Wellman-Lord System be utilized for this project. The technical and economic bases for this recommendation are given. (ERA citation 05:030079)
