Comparison of Supercritical Water Oxidation and Supercritical Water Gasification
William Jacoby¹ ; ¹University of Missouri, Columbia, United States;
Paper Id: 136 [Abstract]

This presentation: (1) reports on current investigation of SCWG of fecal sludge to produce fuel gas in a plug flow reactor; (2) reports on current investigation of SCWO of fecal sludge to produce heat in a plug flow reactor; (3) compares and contrasts technologies, focusing on mass balances, energy balances, feasibility, and reliability; (4) reports on current operation of pilot-scale SCWO unit, sited at Duke University, for neighborhood-scale treatment of fecal sludge in the third world. The research discussed is funded by the "Re-invent the Toilet Program" sponsored by the Bill and Melinda Gates Foundation. The goals of this program will also be discussed.

High-Pressure, Density-Driven Separation of Carbon Dioxide from Flue Gas
William Jacoby¹ ; ¹University of Missouri, Columbia, United States;
Paper Id: 137 [Abstract]

High-Pressure, Density-driven Separation (HDS) technology was invented and reduced to practice at the University of Missouri. Research, development and commercialization activities continue at Mizzou in conjunction with Liquid Carbonic LLC. HDS technology has the potential to be a powerful weapon against climate change. Based on experimentation, thermodynamic analyses, and modeling, our estimated operating cost is about $15 per metric ton of CO2 removed, which is less than one-third current state-of-the-art technologies. We have defined a volumetric efficiency metric that, at the time of abstract submittal, had increased nearly 300-fold relative to our original (published) experiments. The HDS itself has no moving parts and, for a given separation rate, its dimension continues to shrink as we optimize performance. Therefore, capital costs will also be low. We will also report on applications of HDS technology for upgrading fuel gasses containing CO2, as well as for H2 separations, all without membranes.
