Appl. No.:

10/407141

Inventors:

Sergei Babko-Malyi - West Windsor NJ, US
Richard Crowe - Hazlet NJ, US

Assignee:

Plasmasol Corporation

International Classification:

B01J019/08

US Classification:

204/164000, 422/186040

Abstract:

A system and method for the injection of an organic based reagent into weakly ionized gas to generate chemically active species. The organic based reagent may be a combination of an organic additive (e.g., an alcohol or ethylene) mixed with an oxidizer (e.g., oxygen) prior to being introduced in the weakly ionized gas. Alternatively, the organic based reagent may be the injection of an organic additive alone in the weakly ionized gas while in the presence of air (non vacuum chamber) that inherently contains oxygen and serves as the oxidizer. Also, the organic based reagent may comprise an organic additive that itself includes an oxidizing component such as EO. In this situation the oxidizing component of the organic component when injected into the weakly ionized gas forms hydroxyl radicals that may be a sufficient oxidizer to eliminate the need for a supplemental oxidizer. Regardless of the organic based reagent used, the organic additive reacts with the oxidizer while in the presence of weakly ionized gas to initiate the production of chemically active species. This system and method may be used for sterilization whereby the increased concentrations of generated chemically active species accelerate and improve overall destruction rates of undesirable chemical and/or biological contaminants on surfaces and/or in fluid streams.

Abstract:

A modular sterilization system including a modular sterilization section divided into a plurality of compartments. The system further includes a plurality of units, each unit being closable and received within one of the compartments of the modular sterilization section. A gas discharge generator is disposed in fluid communication with each unit to generate a weakly ionized gas that sterilizes the object(s) to be treated that are housed therein. Power is provided independently to only those compartments in which a corresponding unit has been properly installed. An electric field is thereby generated only in the generators of those units that have received power. As a result, the weakly ionized gas is emitted from the generator in which an electric field has been created in situ of an object to be treated.
