US 5,308,610 A · Odor control composition and method of using same

Abstract

A method of controlling odors from a hydrocarbon-containing sludge including the steps of mixing a quaternary ammonium compound with water, adding a surface-active agent to the mixture of the quaternary ammonium compound and water, and dispersing the mixture into the hydrocarbon-containing sludge. A masking agent may be introduced to the mixture of the water, the quaternary ammonium compound, and the surface-active agent. A pH control agent is added to this mixture, along with a quantity of a polyglycol ether. The quaternary ammonium compound is benzalkonium chloride. The surface-active agent is butyl cellosolve. The masking agent is limonene. The step of dispersing the mixture includes spraying the mixture onto the hydrocarbon-containing sludge.
