Title: Ryo Den: Innovator in Air Separation Technology
Introduction
Ryo Den is a notable inventor based in Hyogo-ken, Japan. He has made significant contributions to the field of air separation technology, holding 2 patents that showcase his innovative approach to producing high-purity nitrogen and oxygen gases.
Latest Patents
One of Ryo Den's latest patents is an "Apparatus for Air Separation." The objective of this invention is to separate air at a low power cost to produce high-pressure nitrogen gas and oxygen gas by utilizing the cold of liquefied natural gas (LNG). The process involves pre-purifying feed air and introducing it into a cryogenic separation unit, where oxygen and nitrogen gases are separated. The nitrogen gas is then cooled and compressed for external use.
Another significant patent is the "Ultra High Purity Nitrogen and Oxygen Generator Unit." This unit is capable of simultaneously producing ultra-high purity liquid nitrogen and liquid oxygen. It features a first rectification column divided into upper, middle, and lower parts, with a nitrogen condenser connected to the upper section. The second rectification column includes a reboiler that aids in the separation of lower boiling point components, resulting in the recovery of ultra-high purity liquid oxygen.
