TREATMENT METHOD AND TREATMENT APPARATUS FOR WASTE GAS OF ETHYLENE OXIDE GAS STERILIZER

摘要

PROBLEM TO BE SOLVED: To provide a treatment method and a treatment apparatus for a waste gas from an ethylene oxide gas sterilizer by which a high concentration waste gas and a low concentration waste gas can efficiently and economically be treated with a small size.

SOLUTION: The treatment method for a waste gas from the ethylene oxide gas sterilizer comprises steps of burning a high concentration waste gas discharged at first out of the ethylene oxide gas sterilizer in a combustion furnace and catalytically burning a low concentration waste gas discharged out of the ethylene oxide gas sterilizer during aeration operation by using a catalytic combustion apparatus.
