Title: Douglas V Eyre: Innovator in Cryogenic Gas Purification
Introduction
Douglas V Eyre is a notable inventor based in Walnut Creek, CA (US). He has made significant contributions to the field of cryogenic gas purification, holding a total of 2 patents. His work focuses on the ultrapurification of liquefied gases, which is crucial for various industrial applications.
Latest Patents
One of his latest patents is a cryogenic gas purification process and apparatus. This invention involves a sophisticated method for the ultrapurification of cryogenic low boiling liquefied gases such as oxygen and nitrogen, which often contain trace impurities. The process begins with the introduction of impure gas into a first distillation column, where it is maintained at its liquid-gas equilibrium temperature. The gas is then separated by distillation into a first vapor fraction containing low boiling point impurities and a first liquid fraction containing high boiling point impurities. The first vapor fraction is subsequently withdrawn and introduced into a second distillation column, where it undergoes further separation. The final product is a second liquid fraction that is free of trace impurities. Cooling for this process is achieved through indirect heat exchange with a cryogenic low boiling gas, such as nitrogen or oxygen.
