Effective Purification of Biogas by a Condensing‐Liquid Membrane

Abstract

Coming clean: Impurities and carbon dioxide in raw biogas are separated by a “condensing-liquid membrane”, based on the different solubility of components in a very thin continuously refreshed water layer in a hydrophilic porous membrane (see picture; blue areas: thin water layer in the porous membrane). Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents are peer-reviewed, but not copy-edited or typeset. They are made available as submitted by the authors. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.
