    摘要： The invention provides a method of removing emulsified oil from an industrial wastewater stream. According to the method, a vinylamine polymer is added to the oil containing wastewater in a concentration of from about 0.1 to about 100 parts per million based on the total volume of the water being treated. The vinylamine polymer includes from about 1 to about 100 mole percent vinylamine and from about 1 to about 99 mole percent of at least 1 monomer selected from the group consisting of amidine, vinylformamide, vinyl alcohol, vinyl acetate, vinyl pyrrolidinone and the esters, amides, nitriles and salts of acrylic acid and methacrylic acid. The addition of the polymer to the oil containing wastewater causes the emulsified oil to flocculate. The flocculated oil is then removed from the wastewater.

    摘要： Demulsification of a water-in-oil, especially a water-in-crude oil, emulsion is effected by contacting it with an aqueous composition having at least one oil-soluble demulsifier and at least one water-soluble surfactant. These aqueous formulations are advantageous over conventional organic formulations of demulsifiers, as the need for toxic and/or flammable/combustible organic solvents is eliminated.
