Abstract

Framgangsmåte og apparat for fjerning av etylenoksid brukt til sterilisering av gjenstander i et vakuumsteriliseringskammer (5) ved hjelp av ei pumpe (10) forbundet med steriliseringskammeret (5) som fører etylenoksid etter sterilisering til en gassvasker (15) som arbeider med syre. Steriliseringskammeret (5), pumpa (10) og gassvaskeren (15) danner en lukket gasskrets; pumpa (10) fører : etylenoksid kontinuerlig fra steriliseringskammeret (5) til gassvaskeren (15), og avgassen fra gassvaskeren (15) tilføres til i steriliseringskammeret (5). Etylenglykol dannet av etylenoksid i gassvaskeren (15) fjernes kontinuerlig fra gassvaskeren (15), og ny syre tilføres gassvaskeren (15) kontinuerlig avhengig av syreforbruket. Denne syklus opprettholdes inntil den resterende konsentrasjon av etylenoksid i gasskretsen faller til under et forutbestemt nivå. En inertgasskilde (48) er fortrinnsvis forbundet med gasskretsen (5,35,10,39,15,40,38) for å tilføre inertgass til gasskretsen på en kontrollert måte når etylenoksidfjerning forårsaker trykkfall i gasskretsen, hvorved trykkfallet i gasskretsen er justerbart.
