摘要： Sulfur dioxide and particulate contaminants are removed from industrial waste gases by a method which provides for a highly active sulfur dioxide reactant to be utilized and regenerated. The method further includes discharging stable, insoluble sulfur containing compounds thus eliminating possible reintroduction of sulfur into the environment and regeneration of the sulfur dioxide reactant by using carbon dioxide contained in the stack gas stream.

摘要： A carbon filter having an elongated cylindrical housing with a cylindrical filter assembly located axially therein, the cylindrical filter assembly having a plurality of flow-through geometrically shaped axially extending exit and entrance chambers with a loosely packed carbon filter bed therebetween. The entrance and exit chambers are positioned equidistant from each other in alternating fashion, with each flow-through entrance chamber advantageously adjacent at least two flow-through exit chambers and each flow-through exit chamber advantageously adjacent at least two flow-through entrance chambers. The filter assembly additionally comprises a forced-feed charcoal reservoir means maintaining a constant pressure on the loosely packed bed to keep it filled.
