Abstract

Decontamination systems and methods are disclosed. In one embodiment, a system comprises a first adsorption/desorption subsystem that is configured to receive a contaminated gaseous solution and remove substantially all of the contaminants from the contaminated gaseous solution during an adsorption cycle, while a second subsystem is configured to purge captured contaminants during a desorption cycle. An evacuator is configured to drive potentially flammable gas compositions from the subsystem operating in a desorption cycle back into the system such that potentially flammable gas compositions are purged from the subsystem operating in the desorption cycle at the beginning of the desorption cycle. A heat source is configured to heat contaminants adsorbed in the adsorption/desorption subsystems to remove the contaminants from the adsorption/desorption subsystems in a gaseous state during their respective desorption cycle.
