Description:

Throughout the United States and around the world, a variety of industries are moving from conventional solvents (e.g., toluene, xylene, acetone, mineral spirits) to high flash solvents including dibasic and other esters, glycol ethers, terpenes (d-limonene isomers), etc. Although these materials are expensive, little recycling is practiced. The primary reason for this situation is that conventional waste reclamation technology, such as distillation and filtration, can not be cost effectively implemented on this scale or is unsuitable for this solvent recovery. In response to the inadequacies of conventional solutions, Media and Process Technology, Inc. (M&P) has developed an innovative, low- cost, high-performance ceramic membrane technology that can recover high quality high flash solvents from spent material. This technology is cost effective at very small scales and is environmentally friendly. Moreover, it has dual use capability because it can be used to recover spent rinse waters in these industries. The solvent reclamation technology has been successfully demonstrated at the pilot scale in the Phase I effort. Excellent solvent quality was obtained over three simulated reuses.

In Phase II, field demonstration testing will be performed to demonstrate the proposed process and its long-term operating stability and to document its removal efficiency for future commercialization.
