摘要

The major goal of this grant is to provide a technical assessment of those factors that contribute to the economic feasibility for the commercial use of the ''Low Energy Distillation Process'' of Victor Thayer (US Patent No. 4,267,736). The activity had for its purpose the examination of the Thayer process in two separate environments. The first was in using this innovation with a crude oil column; the second, using it with a ''clean'' service distillation. Given some positive results from either of these applications, a follow-on technical assessment in the commercial community would occur. A preliminary cost analysis with a crude oil column showed a significant advantage in favor of the Thayer method. However, a substantially increased yearly maintenance cost made it economically doubtful for implementation with a crude-oil column. Further analysis substantially verified earlier comments by ''Cf-Engineer X''. There may, however, be an acceptable application of the Thayer method to smaller scale ''clean'' service cases with essentially non-fouling fluids. The analysis of the ''clean'' service distillation suggested that a higher capital and greater maintenance costs than existing technologies would probably result. Hence, the Thayer process was ruled out for revamp applications and considered to be unlikely to be useful in new plants of this type. This study also indicated that there may, indeed, be some specialized duties that favor the use of the Thayer method and that future effort should be directed into identifying applications of this type and into reducing the cost of the heat transfer coils required.
