Carbon capture & storage (CCS) with high rates (90-99%) will be necessary to keep natural gas around in a low-carbon future. Furthermore, as intermittent renewable energy expands, power plants have operate at low-load conditions more frequently. To meet these demands, we propose combined cycle (NGCC) plant hybrid CCS system that can attain and easily between high-load conditions. More specifically, an integrated where exhaust is first processed by membrane then solid sorbent system. We...
Abstract A Monte Carlo simulation has been developed to describe the gas phase coagulation and sintering of nan-oclusters. The cluster-cluster aggregation model is modified include a finite interparticle binding energy. Particle restructuring densification (sintering) are incorporated into by modifying Kadanoff's algorithm for random particle walks on surface cluster. effect aggregate size distribution fractal dimension investigated in simulations two-dimensional clusters. energy relative...
Abstract Surface pattern is a promising approach to enhance membrane performance while contradictory results have been reported on its impact concentration polarization. Here, we provide an experimental and modeling study of the polarization patterned membranes by varying size, solute surface hydrophilicity, orientation. Interesting trends were observed when comparing different orientations, where relative degree (CPD) was found depend molecular weight. Salts small organic molecules...
Flat sheet membranes offer many advantages over other membrane configurations, (e.g. ease of maintenance and low pressure drops) that make them a strong candidate for post-combustion carbon capture. A performance model stacked flat module is reported in this work. The based on the specifications Gen 2 Polaris™ developed by Membrane Technology & Research (MTR) predicts solution governing momentum mass balance equations. accounts variability flow channel heights within can arise during...
Abstract An analysis of the effects nonuniform fiber packing on external mass‐transfer coefficients for axial flows through bundles parallel, axially oriented fibers is presented in entry limit. In this limit, one can obtain an analytic solution to boundary‐layer equations terms velocity gradient surface either a constant wall flux or concentration. To explicitly calculate coefficients, numerical approximation obtained from conservation momentum using boundary‐element method. Results...
Abstract A thermodynamic framework for the analysis of gas sorption in glassy polymers is established limit low levels. The results represent an extension Flory‐Huggins theory to materials with nonzero internal energy changes due deformation; recovered zero polymer bulk modulus. isotherm expressed terms penetrant vapor‐phase activity, physical properties, partial molar volume, and heat mixing. qualitative form shown be unrelated presence excess free volume polymer; only quantitative...
Abstract The rheology of the melt hollow fiber spinning process is examined in thin filament limit. resulting equations are also applicable to single‐phase and two‐phase extensional flows. Using a novel numerical solution procedure, sensitivity material property variations investigated. Fiber geometry directly controlled by mass flowrates core clad fluids while spinline tension most strongly influenced viscosity. A maximum can occur stress profile if liquid used ratio viscosity increases...
Traditional methods for water treatment are not effective to remove micro pollutants such as harmful organics and cannot meet the demand high-quality drinking water. Membrane technologies known produce of highest quality. However, membrane fouling is a significant problem, which limits widespread use these technologies. Currently, chemical cleaning used control fouling, interrupts production process during cleaning, produces secondary pollutants, shortens life due erosion, adds costs...
