Fundamental Studies of Plasma Air Separation

Investigator

Mark Cappelli, Mechanical Engineering, Stanford University

Objective

This research explores the use of an atmospheric-pressure dielectric plasma discharge to enrich an air flow with oxygen, with the ultimate goal of providing a novel low-cost technology for air separation. This work will lead to better understanding of the fundamental challenges that need to be addressed to generate negatively charged oxygen ions in such a plasma configuration and to effectively separate oxygen by having the plasma impart momentum to the neutral air molecules. Results from this project will provide the scientific basis necessary to assess the feasibility of this air separation technology.
