Common use of Process Description Clause in Contracts

Process Description. The Interline Process relies on propane extraction followed by vacuum distillation to clean and re-refine Used Oil. The recovered Base Oil may require clay or an equivalent finishing step to produce the required colors mentioned in Exhibit B, entitled "Specifications". The first step of the process dissolves the Used Oil with propane and rejects most of the Used Oil additives and any water present in the feedstock to the Unit. The water is sent to an industrial sewer (supplied by Purchaser) while the additive package is blended with the heaviest Oil from the vacuum distillation section to produce an asphalt extender. Other alternatives for disposal of water (supplied by Purchaser) include use of evaporative cooler, use of a fired heater and removal from site for disposal at another facility. The propane is recovered from the Oil-propane mix and reused to dissolve additional Used Oil feedstock. The Oil is then further refined by boiling the lighter gasoline and diesel material out of the Base Oil. The Base Oil is then distilled to improve color and remove metals or other impurities that may be present. A clay treatment or equivalent finishing step will be used to meet the color specification as detailed in Schedule B.
