ABSTRACT:
The invention provides an optimized method and system for conducting a continuous-operation, closed-loop, flow-through vapor phase decontamination. By the method, a liquid decontaminant is vaporized and delivered into, through and out of a sealable chamber by means of a carrier gas that is recirculated in a closed-loop conduit circuit. After leaving the chamber, the vapor is decomposed and the carrier gas is partially and selectively dried in response to the monitored temperature, relative humidity, and decontaminant vapor concentration in the chamber. The degree of drying is particularly selected in response to these chamber parameters to maintain a predetermined percent saturation of the decontaminant vapor in the chamber.
