In 1975, the U.S. Environmental Protection Agency awarded a contract to the Ministry of Smelting Poland for research to minimize emissions of fugitive pollutants from copper smelters and to assist in the control of smelter pollutants. The project objectives were to develop procedures for operating copper converters for steady gas flow containing relatively high concentrations of SO2; to improve cleaning and treating of particulates in the converter gas streams to allow better operation of SO2 removal systems, such as contact sulfuric acid plants; and to show how procedures and results that were developed could be applied to various types of copper smelters encountered in industry. During the course of the project, portions of the PL-480 funding were utilized to evaluate the Hoboken Converter, a potential substitute process providing stricter environmental control of fugitive SO2 and particulate from copper converting.
