| Abstract: | The fouling and danger in the sour water stripping system of the desulfurization unit in Changling Refining & Chemical Company were introduced. The higher ammonium naphthenate reduced the surface tension of the sour water, which made it difficult for the impurities to precipitate. As the result, the impurities were carried over to the stripper. When heated, the ammonium naphthenate, discomposed and deposited, fouling the equipment. Controlling the surface tension of the sour water at greater than 55 mN/m or addition of demulsifier and application of filtration could mitigate the fouling. |
