Until now, U.S. industry could not justify the expense associated with resource recovery compared to waste disposal from many waste streams. However, a new technique to recycle and reuse previously disposed petroleum products may provide some financial relief to industry.
With the help of a NICE3 grant from the U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency, Lubrizol Corporation of Deer Park, Texas, will evaluate the feasibility of using a closed loop propane/butane-based solvent extraction system to recover organic material from solid wastes currently disposed of off-site. In addition, this project may treat waste oil and water streams to permit reusing and recycling petroleum products.
With the solvent extraction technology, the anticipated products are non-organic filter cakes that will not present hazards in landfills and organics that can be recycled/reused. The process uses liquified propane or butane to dissolve organic products from the filter cakes and waste oil/water streams. No harmful products are emitted and energy consumption is minimal, whereas conventional treatment systems offer expensive and environmentally unfriendly options. Moreover, the possibility exists for filter cakes to replace alternate feed materials, eliminating the need to dispose of any material currently in the solids stream.
Lubrizol has divided this study into three phases, with phases II and III contingent on the success of previous phases. Phase I is a preliminary proposal and bench-scale testing; phase II is pilot-scale testing; and phase III is preparation of a schedule A engineering package, construction, and operation.
