A Basis for a theoretical description of the limestone injection - wet scrubbing process for removal of SO2 from power plant flue gases is given. A literature survey yielded the pertinent chemical data for the aqueous system. A computer program to calculate the partial pressures of SO2 and CO2 above aqueous solutions containing Ca(++), Mg(++), Na(++), NO3(-), CO2, SO2, SO4(-2), and C(-) was written and checked against experimental data. Turbulent contact absorbers and marble bed absorbers were described mathematically. Thermodynamic data for the dissociation constants of CaSO3 and MgSO3 and the solubility product constant for CaSO3 . 1/2H2O were determined experimentally. Sulfur dioxide sorption systems were simulated that approximate the process used at Kansas Power and Light and the process to be used in the NAPCA prototype system at TVA's Shawnee Power Plant. Flow rates, stream compositions, and important process variables are given. (Author)
