Description:
The report gives results of IERL-RTP in-house studies in which equilibrium partial pressure of SO2 was measured as a function of pH, temperature, and concentration of sulfur (IV) on various scrubber liquors. These studies were done for potassium-, sodium-, and citrate-based scrubbing systems. It is shown that equations developed by earlier workers for predicting SO2 partial pressures are incorrect. Theoretical expressions are developed to relate the equilibrium partial pressure of SO2 to the important scrubber parameters. These expressions are experimentally validated at the 90 percent confidence level.
