Sulphur Dioxide Removal from Waste Gases: A Status Report Japan

Part of the Environmental Science Research book series (ESRH, volume 2)


Desulfurization of waste gases is assuming growing importance in Japan parallel to the mounting use of heavy fuel oil, which contains 2.5% sulfur on the average. Although many plants for hydrodesulfurization of heavy fuel oil—with a total capacity of nearly 500,000 barrels per stream day—are in operation and in 1971 by-produced 350,000 metric tons of elemental sulfur, approximately 5 million tons of sulfur dioxide was emitted by the combustion of heavy fuel oil in that year. In addition, sulfur dioxide in waste gases from chemical plants, oil refineries, smelteries, and coal-burning boilers presents some problems. The yearly average of sulfur dioxide concentration in the polluted districts of major cities ranged from 0.05 to 0.09 ppm in 1970.
