DYPAK: A Porous Membrane Material for Use as Structured Packing in Distillation

Abstract

DYPAK is a new advanced membrane material for olefin and paraffin separations. Over 75 billion pounds of these materials are distilled annual in the US. The energy consumption of the current distillation methods are huge--over 400 trillion BTUs annually in the US alone. DYPAK is a new technology that uses parallel tubes of advance membrane materials to separate olefinic and/or paraffinic mixtures from light gas byproducts with much greater energy efficiency. LANL scientists estimate that over 46 trillion BTUs can be saved using DYPAK in the US. Moreover, DYPAK separation facilities are scalable, enabling smaller economically viable separation plants and plant expansions.More information:
