Title: Motojuro Yamaya: Innovator in Alcohol Recovery Technology

Introduction

Motojuro Yamaya is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of chemical engineering, particularly in the recovery of lower alcohols from mixtures. His innovative approach has implications for various industries, including semiconductor manufacturing and lens production.

Latest Patents

Yamaya holds a patent for a process and apparatus designed to recover lower alcohol from a mixture with water. This process is particularly useful in vapor drying procedures for water-wetted articles, such as water-washed lenses or semiconductor wafers. The method involves feeding a mixed liquid of lower alcohol and water into a vaporizer, where it is vaporized. The resulting mixed vapor is then directed into a gas-separating module that utilizes a gas-separating membrane. This membrane selectively allows water vapor to permeate, while the non-permeated vapor fraction, which contains a higher concentration of lower alcohol, is withdrawn and converted into a high-purity liquid.

Career Highlights

Throughout his career, Yamaya has worked with prominent companies, including Ube Industries, Inc. and M. Watanabe & Co., Ltd. His experience in these organizations has allowed him to refine his expertise in chemical processes and patent development.
