Pressure swing adsorption (PSA) processes have been used extensively for gas separation, especially in the separation of hydrogen from CO2, and air purification. The objective this paper is to examine economic feasibility pressure recovering CO2 postcombustion power plant flue gas. analysis considers both high-pressure feed vacuum desorption using commercial adsorbent 13X, which has a working capacity 2.2 mol/kg CO2/N2 selectivity 54. results show that reduces capture cost US$57 US$51 per...
This review provides a critical overview of chlorine evolution reaction (CER) including fundamental understanding mechanisms, recent advances in developing CER catalysts, and future opportunities this field.
Studies of CO2 capture using membrane technology from coal-fired power-plant flue gas typically assume compression the feed to achieve a driving force across membrane. The high cost these systems reflects need compress low-pressure (1 bar) and low purity product stream. This article investigates how costs for membranes can be reduced by operating under vacuum conditions. is pressurized 1.5 bar, whereas permeate stream at 0.08 bar. Under conditions, U.S. $54/tonne avoided compared $82/tonne...
Chemical absorption is widely regarded as the most promising technology for CO2 capture from large industrial sources in short term. The cost of postcombustion power plants using monoethanolamine (MEA), benchmark chemical absorption, currently over US$70 per metric ton avoided. This high considered major obstacle to current large-scale implementation carbon and storage (CCS). Thus, there has been significant focus on development new solvents with aim reduce costs. paper provides insights...
A computational fluid dynamics (CFD) code was used to study the effects of Reynolds number, mesh length, and filament diameter on mass-transfer enhancement for three spacer configurations, a cavity, zigzag, submerged spacer. For cavity zigzag spacers, first increases with decrease in reaches maximum, then decreases further while pressure loss showed continuous increase length. The shows all types, mass transfer diameter. However, at smaller diameter, overall performance increases, as...
Abstract This paper is written in response to the “How green blue hydrogen?” by R. W. Howarth and M. Z. Jacobson. It aims at highlighting discussing method assumptions of that paper, thereby providing a more balanced perspective on hydrogen, which line with current best available practices future plant specifications aiming low CO 2 emissions. More specifically, this we show that: (i) simplified Jacobson used compute energy balance hydrogen plants leads significant overestimation emissions...
Insights into the effect of spacer filaments in membrane systems on flow pattern were obtained using a computational fluid dynamics code. The patterns examined for single filament adjacent to wall and centered channel three different configurations, cavity, zigzag, submerged spacers, with variations both mesh length diameter Reynolds numbers ranging from 90 768. Large recirculation regions formed behind filaments, around increased shear stress wall. For an identical number diameter, produced...
Abstract The structure of individual reverse osmosis modules, the configuration module network, and operating conditions were optimized for seawater brackish water desalination. system model included simple mathematical equations to predict performance modules. optimization problem was formulated as a constrained multivariable nonlinear optimization. objective function annual profit system, consisting obtained from permeate, capital cost process units, costs associated with energy...
