Each year, more than 4 billion gallons of spent lubricants are generated worldwide. Although they can be considered a valuable renewable resource, less than 10% of the worldwide supply is actually re-refined into high-quality lubricant basestocks. The remainder is typically burned as fuel or disposed of using even less environmentally friendly methods. The disadvantages of conventional re-refining technologies combine to simply render these technologies useless outside of highly populated metropolitan areas where large quantities of spent lubricants are generated in a centralized location. Re-refining technology that can be employed on a small scale is required throughout most of the United States, but until now has simply been unavailable. In response to the inadequacies of conventional solutions, Media and Process Technology, Inc. (M&P) has developed the LubriClear Process, an innovative technology that combines several M&P proprietary technologies into a hybrid recycling/re-refining process to deliver high-quality base oils from spent lubricants. During Phase I, M&P achieved its primary objectives by dramatically improving the overall operating cost and demonstrating the economic viability of the process. In parallel with the Phase I activity, M&P has designed, constructed, and installed a field demonstration unit. The successful completion of the Phase II project will verify the technical and economic viability of the improved LubriClear process at a field demonstration unit for an extended period, which is essential for future commercialization.
