Title: Innovations in Distillation: Lee H. Lynd

Introduction

Lee H. Lynd, an accomplished inventor based in Meriden, New Hampshire, has significantly contributed to the field of chemical engineering through his inventive processes in distillation. With a strong focus on enhancing the efficiency of ethanol production, Lynd has been granted two patents that reflect his innovative approach to this crucial industrial process.

Latest Patents

Lynd's latest patents are centered around a novel distillation process for ethanol. The method employs a heat pump, which can be driven by a compressor, utilizing a vapor stream from within the distillation system as a heat source and a liquid stream as a heat sink. This innovative selection of heat-source vapors and heat-sink liquids is designed to optimize energy efficiency.

One patent details a system where streams are withdrawn from the phase-contacting region of the distillation system and returned at different temperatures than those at which they were withdrawn. Specifically, vapor removed is returned at or below the temperature of extraction, while liquid is returned at or above. This methodology reduces the overall heat requirements of distillation by minimizing the temperature difference between heat sources and sinks, thus requiring less energy in the process. Furthermore, the patent describes combinations with other distillation methods and systems aimed at effectively separating ethanol-water mixtures, highlighting extensive heat integration to optimize efficiency.
