PEROXYACID COMPOUND USE IN ODOR REDUCTION

摘要

Disclosed is a process for the treatment of a plant fluid effluent containin g odor compounds including an alkyl mercaptan or an alkyl thiol, an amine compound, ammonia, hydrogen sulfide and mixtures thereof by contacting the plant effluent in either a counterflow or cocurrent flow process. In the process, the effluent is contacted with an aqueous solution comprising a peracid compound and optionally an essential oil. When contacted with the peracid, odor compounds in the efflue nt are oxidized and converted from the gaseous phase into a chemically modified highly aqueous soluble phase in the aqueous treatment. I n this way, odor removal from the gas is preferred and odor compounds are efficiently transferred into the aqueous treatment solution. T he use of such a process produces a significant improvement in odor quality index as measured by a conventional process using an expert pan el when compared to conventional treatment methods.
