OSTI ID:5891191

The findings of an investigation on potential use of the Braton-cycle for solvent recovery are discussed. Section 3 describes the basic Brayton cycle principle and the various methods of recovering solvents. The presently used solvent recovery systems of carbon and condensation by mechanical refrigeration are described and incineration is discussed as an alternate method to reduce solvent emissions to the atmosphere. Candidate Brayton-cycle systems selected for further evaluation are depressed freezing (closed loop); desiccant (open loop); and carbon desorb. The potential industrial applications for the candidate Brayton-cycle concepts and the market potential that could be expected are described in Section 4. All industries that manufacture, market, synthesize, process, coat, or clean with volatile organics were considered. An economic analysis in Section 5 of the candidate solvent recovery systems shows that the cost of incorporating any of the systems can be justified on the basis of the payback value of the recovered solvent. The method of conducting site surveys is discussed. The 3M tape coating facility located in Hutchinson, Minnesota, was chosen as the demonstration site. Results of recovering solvents from one or another oven zones using the closed loop Brayton-cycle solvent recovery system are detailed. (MCW)
