Interess, E. EVALUATION OF THE GENERAL MOTORS' DOUBLE ALKALI SO2 CONTROL SYSTEM. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/7-77/005.
Description:
The report is an evaluation of the double alkali flue gas desulfurization (FGD) system, installed to control SOx emissions from the coal-fired industrial boiler complex at General Motors' Chevrolet plant in Parma, Ohio. It describes the boiler and FGD systems. It addresses performance with respect to SO2 removal, filter cake properties, lime stoichiometry, carbonate softening, soda ash stoichiometry, scaling, oxidation, and reliability. The evaluation is presented in terms of three 1-month-long intensive test periods and a longer-term non-intensive test period. System material balances are presented for some of these periods. A general history of the operation is also presented.
