Title: Takeshi Tamaru and High-Purity Nitrogen Separation

Introduction

Takeshi Tamaru is an inventor associated with Okayama, Japan, and Kuraray Chemical Co., Ltd. His patent work focuses on pressure-swing adsorption processes for separating high-purity nitrogen from gas mixtures. His listed portfolio includes 2 patents.

Latest Patents

Tamaru’s patents describe methods for improving nitrogen purity through pressure-swing adsorption, a process that separates gases by cycling adsorbers through pressurization and regeneration.

“Process for separating nitrogen gas” describes transferring gas between an adsorber that has completed adsorption and one that has completed regeneration, while discharging part of the transferred gas from the system. The method is designed to produce nitrogen with a purity of at least 99.99% using compact equipment.

“Process for separating nitrogen gas by pressure swing adsorption system” also uses carbon molecular sieve adsorbent. It specifies stopping gas transfer before pressure equalization is established and promoting regeneration by causing some product gas to flow backward. The patent describes an economical way to obtain 99.99%-pure nitrogen from air.

Career Highlights

Tamaru’s listed inventions address a technical challenge in nitrogen production: achieving very high purity with pressure-swing adsorption equipment. The processes use carefully controlled gas transfer and regeneration steps to improve separation performance.
