The rapid increase in global industrialization necessitates technology shifts in
energy production, manufacturing, and carbon management techniques. Large
energy costs in refineries, power plants, and manufacturing facilities using
traditional separation techniques are currently a major opportunity for
innovation. Approximately 10% of global energy use can be attributed to
separation processes, with the vast majority of separations being “thermal” in
nature (e.g., distillation). Significant energy and cost savings can be realized
using advanced separation techniques such as membranes and sorbents. One
of the major barriers to acceptance of these techniques remains linking
engineering materials to actual processes that are effective in the presence of
aggressive industrial feeds.
The creation of robust materials-enabled advanced separators and their
manufacturing into low-cost, energy-efficient devices to meet this global
challenge will be the focus of the talk. Engineering novel materials—such as
zeolitic imidazolate frameworks, polymers of intrinsic microporosity, and carbon
molecular sieves—into hollow fiber separation devices shows promise for
emerging separation applications. These include natural gas liquid fractionation,
olefin/paraffin separation, carbon capture, and organic solvent purification.
Specifically, a highly heat integrated sub-ambient pressure swing adsorption
process that enables ultra-high swing capacities using robust metal-organic
frameworks will be discussed. Synthesis and formation of advanced composite
materials, mass transfer of small molecules through these materials, and an
outlook for energy- and cost- efficient separations will be discussed. The dual
advance of novel materials engineering and scalable separation device
manufacturing will enable use of membranes and sorbents in critical industrial
separation processes.
