System and method for removing sulfur-containing contaminants from indoor air

Abstract

A system and method for removing sulfur-containing contaminants from indoor air includes a panel system having a first layer and a second layer. The first layer can include a base media onto which sodium bicarbonate is attached. The second layer can include a base media onto which activated carbon is attached. Indoor air including sulfur-containing contaminants can contact and pass through the first layer. Sulfuric acid can react with the sodium bicarbonate to produce sodium sulfate, which can, in turn, act as a drying agent for organic sulfur-containing contaminants in the indoor air, such as carbon disulfide and carbonyl sulfide. As a result of such drying, the second layer can more effectively trap and/or bind (adsorb) the organic sulfur-containing contaminants so that these contaminants are removed from the contaminated air. The treated air can be returned to an indoor space of the structure.

1 . A method for removing sulfur-containing contaminants from indoor air comprising:
 providing a panel system with a first layer and a second layer, the first layer having a base media and sodium bicarbonate associated therewith, the second layer having a base media and activated carbon associated therewith;   a gas flow including sulfuric acid and sulfur-containing contaminants coming into contact with the first layer of the panel system such that the gas flow passes therethrough and such that the sulfuric acid chemically reacts with the sodium bicarbonate to produce sodium sulfate, water and carbon dioxide, wherein the sodium sulfate adsorbs at least a portion of the water produced in the chemical reaction, whereby the sodium sulfate acting as a drying agent for the organic sulfur-containing contaminants;   the gas flow subsequently coming into contact with the second layer of the panel system such that the gas flow passes therethrough and such that at least a portion of the organic sulfur-containing contaminates is adsorbed by the activated carbon, whereby the level of the sulfur-containing contaminants in the gas flow leaving the panel system is less than the level of the sulfur-containing contaminants in the air flow entering the panel system.
