Sudhoff, F. AND R. Torstrick. SHAWNEE FLUE GAS DESULFURIZATION COMPUTER MODEL USERS MANUAL. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/8-85/006 (NTIS PB85243111), 1985.
Description:
The manual describes a Shawnee flue gas desulfurization (FGD) computer model and gives detailed instructions for its use. The model, jointly developed by Bechtel National, Inc. and TVA (in conjunction with the EPA-sponsored Shawnee test program), is capable of projecting preliminary design and economics for lime- and limestone-scrubbing FGD systems, including spray tower, turbulent contact absorber (TCA), and venturi/spray-tower scrubbing options. It may be used to project the effect on system design and economics of variations in required SO2 removal, scrubber operating parameters (gas velocity, liquid/gas ratio, alkali stoichiometry, and liquor holdtime in slurry recirculation tanks), reheat temperature, and scrubber bypass. It may also be used to evaluate alternative waste disposal methods or additives (MgO or adipic acid) on costs for the selected process. Although the model is not intended to project the economics of an individual system to a high degree of accuracy, it allows prospective users to quickly project comparative design and costs for limestone and lime case variations on a common design and cost basis.
