ABSTRACT:
For safe removal and collection of chemical sterilants such as ethylene oxide from a sterilization process, steam or other substantially condesable, inert dilutent gas is used to extract and to transport sterilant from the inside of sterilized materials and the sterilizing chamber into a collection tank. The sterilant and the condensable dilutent are separated when the mixture is discharged from the sterilizing chamber such that virtually all of the sterilant can be collected as a liquid by compression and/or refrigeration at practical pressures and temperatures.
