    SPENT CAUSTICS are also called WASTE CAUSTICS and TOXIC WASTES.

    SPENT CAUSTICS are waste products generated from caustic cleaning solutions, gas scrubber blowdowns, petroleum sweetening, geothermal power generation, and chemical manufacturing processes.


    SPENT CAUSTICS are categorized into various groups, typically based on the compounds of highest concentrations:
     

            • Sulfidic Spent Caustic
            • Disulfidic Spent Caustic
            • Mercaptanic Spent caustic
            • Cresylic Spent Caustic
            • Phenolic Spent Caustic
            • Naphthenic Spent Caustic


    SPENT CAUSTICS contain high levels of any of the following extremely odorous, hazardous, and toxic compounds:
     

            • Sulfides
              • hydrogen Sulfide

            • Disulfides
              • dimethydisulfide
                diethyldisulfide
                methylethyldisulfide

            • Mercaptans
              • methylmercaptan
                ethylmercaptan
                propylmercaptan
                butylmercaptan (skunk spray!)
                allylmercaptan

            • Phenolics
              • phenol
                catechol (o-hydroxyphenol)
                resorcinol (m-hydroxyphenol)
                hydroquinone (p-hydroxyphenol)
                o-, m-, p- nitrophenol
                1-, 2- naphthol

            • Cresylics
              • o-, m-, p- cresol
                dimethylphenol
                ethylphenol

            • Naphthenates
              • cyclohexane
                cyclohexanol
                cyclopentane

            • Amines
              • MEA (monoethanolamine)
                MDEA (methyldiethanolamine)

            • Sodium Hydroxide

            •  
            • Potassium Hydroxide
