Geologic carbon sequestration (GCS) in deep saline aquifers results chemical and transport processes that are impacted by the wettability characteristics of formation solid phases contact with connate brines injected CO2. Here, angle (θ) at CO2–brine–mineral interface is studied for several representative solids including quartz, microcline, calcite, kaolinite, phlogopite, illite under a range GCS conditions. All were found to be water wetting (θ < 30°) subtle but important differences...
In geologic carbon sequestration, capillary pressure (Pc)-saturation (Sw) relations are needed to predict reservoir processes. Capillarity and its hysteresis have been extensively studied in oil-water gas-water systems, but few measurements reported for supercritical (sc) CO2-water. Here, Pc-Sw of scCO2 displacing brine (drainage), rewetting (imbibition) were understand CO2 transport trapping behavior under conditions. Hysteretic drainage imbibition curves measured limestone sands at 45 °C...
Hydrated mineral surfaces in the environment are generally hydrophilic but certain cases can strongly adhere CO2, which is largely nonpolar. This adhesion significantly alter wettability characteristics of surface and consequently influence capillary/residual trapping other multiphase flow processes porous media. Here, conditions influencing between CO2 homogeneous were studied using static pendant contact angle measurements captive advancing/receding tests. The prevalence was sensitive to...
We recently defined a method for fabricating multilayer microdevices using poly(ethylene terephthalate) transparency film and printer toner, showed these could be successfully applied to DNA extraction amplification (Duarte et al., Anal. Chem. 2011, 83, 5182-5189). Here, we advance the functionality of with flow control enabled by hydrophobic valves patterned laser lithography. Laser patterning toner within microchannel induces dramatic change in surface hydrophobicity (change contact angle...
Abstract Capillary pressure ( P c )‐saturation S w ) relations are essential for predicting equilibrium and flow of immiscible fluid pairs in soils deeper geologic formations. In systems that difficult to measure, behavior is often estimated based on capillary scaling easily measured – (e.g., air‐water, oil‐water), yet the reliability such approximations needs be examined. this study, 17 sets brine drainage imbibition curves were with air‐brine, decane‐brine, supercritical (sc) CO 2 ‐brine...
Leakage from geologic carbon sequestration (GCS) sites is inherently challenging to study because CO 2 , driven by buoyant forces, travels over long distances, undergoing phase changes and encountering numerous connate brine formation chemistries as it rises the surface. This work explores effect that has on rheological properties of solutions a range GCS‐relevant temperature, pressure, ionic strength, shear conditions. Under fluid‐liquid equilibrium conditions prevail in deep subsurface,...
A La-modified clinoptilolite adsorbent was developed for phosphorus removal from aqueous solution. The effects of operational parameters such as pH, dosage, contact time and temperature on adsorption were investigated. results showed that the ratio modified (99.45%) significantly improved, which over triple than natural ones (31.50%) under optimum conditions. process well described by pseudo-second-order kinetic model. Moreover, data closely fitted Freundlich isotherm proper pH ranged 5 to...
Abstract The poor mixing caused by zinc powder deposition in purification process is a serious problem which can’t be avoided treatment of zinc-containing solid waste. Here, to enhance the efficiency waste reactor, two kinds multi-blade combined stirring systems are compared with single layer four straight-blade and double-layer (DFB) traditionally chosen industry. This study simulated explored flow field characteristics effects these stirred-tank further proposes unit ion energy (UIPE) as...
Abstract The fluid in the reactor can be poorly mixed, so an eccentric impeller is proposed to improve mixing efficiency. In this investigation, numerical simulations and cadmium removal experiments for purification of zinc sulfate solution were conducted. effect impellers on efficiency was discussed. mechanism concentric arrangement stirring stirred tank elucidated. results showed that average axial velocity system (EIS) 131.52% (CS) 134.23% (ES). hydrometallurgy experiment, unit ion energy...
Lubricants are necessary in tilting-pad journal bearings to ensure separation between solid surfaces and dissipate heat. They also responsible for much of the undesirable power losses that can occur through a bearing. Here, novel method reduce is proposed which conventional lubricant substituted by binary mixture synthetic dissolved CO2. These gas-expanded lubricants (GELs) would be delivered reinforced bearing housing capable withstanding modest pressures less than 10 MPa. For subject loads...
Until now, few studies have analyzed the effects of temperature on cardiovascular disease (CVD) death at different time points. In this study, we chose 9 cities in subtropical and tropical areas China correlation between points CVD mortality. We completed study two steps. First, trend decomposition data related to mortality populations within selected using empirical mode (EMD). Second, created a regression fitting analysis temperatures periods. The results showed that southern Chinese...

Abstract Understanding the main mechanisms affecting long‐term migration and redistribution of injected CO 2 in geological carbon storage is needed for developing predictive models to assess environmental risks designing monitoring schemes. Preparation a postinjection site care plan required injection wells, including pressure changes plume. Knowledge gaps exist regarding assessment timeframes plume because processes driving trapping are not fully understood. In stage storage, occurs mainly...
