In April 1983, Argonne National Laboratory (ANL), Consolidation Coal Company (Consol) and Conoco Coal Research Division successfully demonstrated that sulfur dioxide (SO/sub 2/) emission from a high-sulfur (4.2%) coal could be controlled to the 1979 New Source Performance Standards (NSPS) requirements (90% SO/sub 2/ reduction) using a lime based spray dryer system. Based on these test results, the spray dryer FGD technology appears economically viable for high-sulfur coal, NSPS applications. The relative simplicity of the spray dryer process vis-a-vis wet lime/limestone FGD systems has made it a favorite among western utilities for lower sulfur coals. The Argonne test is further proof that the spray dryer process can be technically and economically extended to higher sulfur coal applications, thus giving utilities another scrubbing option to consider for installations where current environmental laws dictate lower SO/sub 2/ emissions. As a result of our test, several minor modifications to the Argonne spray dryer process and to the operating procedures were implemented. These modifications have improved the reliability of the spray dryer system. 5 references, 6 figures, 6 tables.
