Abstract
Ester-based synthetic lubricants are used in a variety of applications ranging from low- end, two-stroke oils in chain saws and automotive crankcase oils to high-end, high- performance oils in jet turbines and heavy duty truck transmissions. These materials offer a number of advantages over mineral (petroleum)-based oils, including excellent low temperature fluidity, very high viscosity index, and superior thermal, pressure, and oxidative stability. In North America, more than 17 million gallons of synthetic esters valued at more than $130 million are purchased and disposed of yearly. At present, no commercial technology is available to re-refine spent ester-based synthetic lubricants into virgin quality basestocks. Media and Process Technology, Inc., has demonstrated that these materials can be re-refined using proprietary technology based upon a modified version of their mineral re-refining LubriClear Process. Process feasibility has been demonstrated in recent bench treatability tests. Recycled lubricant with near virgin quality specifications has been produced. In the Phase I effort, bench tests will be scaled up to the pilot level to conduct various optimization and long-term performance tests. Additionally, larger volumes of finished product will be produced for finished product blending and performance testing by various lubricant packagers.
