A process for removing sorbed lubricating oil additives from siliceous filter material is provided. The process comprises forming a slurry of the additive-laden siliceous filter material and an aromatic solvent. Water is added to the slurry prior to separating the siliceous filter material from the slurry. The recovered filter material is substantially additive-free. The lubricating oil additives may be optionally recovered from the aromatic solvent by appropriate means such as distillation.

Treating spent filter media

A system is disclosed for rapid on-site analysis of a water-borne oil-slick, which system utilizes a combination of devices designed to permit on-site determination of the water content and specific gravity of the oil/water mixture, and the initial boiling point of the water-free oil.

System for the rapid analysis of water-borne oil spills

Process and apparatus for on the site determination of the characteristics of an oil-pollutant containing water. The determinaton includes the use of a combination of devices designed to permit the on-site determination of the water content and specific gravity of the mixture of water and pollutant, and the initial boiling point of water-free pollutant.
