| titleOfInvention | Process for the treatment of contaminated emulsion |
| abstract | ABSTRACT A process for the treatment of a contaminated water-in-fat type emulsion, such as the waste obtained from a spent rolling oil, in order to recover the fatty component substantially free of contaminants, which includes the steps of: (a) mixing the contaminated emulsion with a volume of water sufficient to increase the total water content to approximately that of the rest of the emulsion; (b) mixing the product of step (a) with a sufficient amount of a short-chain organic acid to lower the pH thereof to less than 5; (c) if necessary, mixing the product of step (b) with an amount of a suitable emulsifier and, if required, an amount of a suitable demulsifier; and (d) allowing the products of steps (b) or (c) to settle to form an upper fat layer substantially free of water and contaminants; a lower aqueous layer; and a precipitate of solid contaminants. |
