Abstract
An so2 emission control program at the St. Joe Minerals Corp.'s zinc smelter powerplant evolved into a cooperative program with the Bureau of Mines for the installation and initial operation of a citrate process flue gas desulfurization demonstration plant. The plant was operated on an intermittent basis from November 1979 to September 1982. The citrate process proved capable of absorption of greater than 90% of the so2 from the flue gas with ultimate conversion to elemental sulfur. However, in order to overcome problems that severely restricted process ontime, plant modifications were made that resulted in lower so2 absorption generally 50% to 70%. Analysis of the operation identified equipment areas where redesign was needed for achieving high so2 removal with reasonable levels of process equipment ontime. The additional investment could not be justified by anticipated smelter revenues. The recent availability of a bubble concept by the environmental regulatory agencies permitted an so2 emissions compliance program that could be implemented on a more timely basis and preclude St. Joe Corp.'s continued involvement in the citrate process flue gas desulfurization development.
