Modeling salt adsorption in electrical double layer for capacitive deionization Open
This work presents an electrical double layer (EDL) model for capacitive deionization (CDI) by intercorrelating the salt adsorption, the electrode voltage, and the surface charge density. The counterion condensation is considered a crucial…

Evaluation of Concentrated Piperazine for CO<sub>2</sub> Capture from Coal-Fired Flue Gas (Final Report, REV0) Open
Concentrated piperazine (PZ) is a novel solvent being developed by the University of Texas at Austin (UT) for CO2 capture from coal-fired power plants. The high thermal stability of PZ permits solvent regeneration at higher temperature (15…

Heat Transfer Enhancement and Optimization of Lean/Rich Solvent Cross Exchanger for Amine Scrubbing Open
The lean/rich amine cross exchanger is one of the cost centers in the amine scrubbing process, and accounts for 20–30% of the capital cost. To minimize the cross exchanger cost, shortcut methods that determine optimum LMTD and fluid veloci…

Optimum heat of absorption for CO 2 capture using the advanced flash stripper Open
Solvent selection is one of the promising ways to reduce energy use of amine scrubbing for CO2 capture. The heat of CO2 absorption is an important property of the solvent. Its effect on total energy use is not obvious: it directly increase…
