System and method for recycling sterilant gas
First Claim
1. A system for recovery of a sterilant gas mixture from a sterilizer chamber, the system comprising:
- a gas recovery tank;
a sterilizer chamber in gaseous communication with the gas recovery tank;
a gas recovery assembly coupled to the gas recovery tank and the sterilizer chamber, wherein the gas recovery assembly is configured to transfer a sterilant gas mixture including at least one sterilant gas between the sterilizer chamber and the gas recovery tank;
an analyzer assembly coupled to the sterilizer chamber, the analyzer assembly including at least one sterilant gas sensor configured to detect density of the sterilant gas; and
a control module coupled to the analyzer assembly and to the gas recovery assembly, the control module configured to determine a transfer pressure for achieving a desired concentration of the sterilant gas and flammability of the sterilant gas mixture as a function of the density of the sterilant gas.

Abstract
A system for recovery of a sterilant gas mixture from a sterilizer chamber is disclosed. The system includes a gas recovery tank, a sterilizer chamber in gaseous communication with the gas recovery tank and a gas recovery assembly coupled to the gas recovery tank and the sterilizer chamber. The gas recovery assembly is configured to transfer a sterilant gas mixture including at least one sterilant gas between the sterilizer chamber and the gas recovery tank. The system further includes an analyzer assembly coupled to the sterilizer chamber, the analyzer assembly including at least one sterilant gas sensor configured to detect density of the sterilant gas and a control module coupled to the analyzer assembly and to the gas recovery assembly. The control module includes at least one control module configured to determine at least one of a transfer pressure and flammability of the sterilant gas mixture as a function of the density of the sterilant gas.
