The Treatment of Waste Metal Cutting Fluid by Extraction and Adsorption Process

Abstract:

A novel recovery process of the effective ingredient from the waste metal cutting fluid was proposed by the combination of solvent extraction and solid adsorption technique. The influence factors such as the volume fraction of 1-butanol, the ratio of solvent to oil, the quantities of KOH and the extraction temperature were studied through experiments. The results show that: The maximum quality of oil sludge was obtained when added 3g KOH to waste liquid(200ml).The mass of oil sludge was found to increase with the increase of solvent to oil ratio until it reached the maximum at the ratio of 3:1.
