Her novel work on oxygen enrichment of air: performance guidelines for membranes based on techno-economic assessment has been published in JMS!
The use of oxygen-enriched air (OEA) is an important strategy for reducing process cost and CO2 emissions in several industrial processes. Membrane-based processes, attributing to their high energy efficiency, are promising alternatives to cryogenic distillation and pressure-swing adsorption (PSA) at small to medium scales. However, so far, the techno-economic assessment of membrane processes has been focused on the production of low-purity O2. This study assesses O2 enrichment by membrane-based processes in a large purity range (30–95%), and reports significant energy and cost savings when high-performance membranes, marked by O2 permeance of 500–1000 GPU and O2/N2 selectivity in the range of 2–20, are developed.
