Coal dust is one of the pollutants generated during coal tunneling process. However, air inlet distance will increase with advancement working face, resulting in redistribution flow field, further affecting pollution characteristics dust. This effect weakens effectiveness removal equipment. Therefore, transient CFD modeling was used to study influence on flow, migration distance, and concentration distribution breathing zone achieve highest reduction efficiency. Results showed that formed...
Abstract During the treatment of oily wastewater produced from polymer flooding (OWPF) by cationic flocculant, oil sludge containing could be formed. In this paper, formation mechanism was discussed for first time and a novel method proposed dissolving sludge. The investigation showed that polyelectrolyte complex formed between flocculant in OWPF. cross‐linked insoluble water. Oil droplets may bound complex, It found can dissolved sodium dodecyl sulphate (SDS) solution, study SDS destroy...
The Protodyakonov's coefficient of coal samples is a key factor affecting and gas outburst, so studying the adsorption pattern with different coefficients can effectively prevent burst accidents. In order to study influence on characteristics coal, seven groups were selected for this study. Gas bodies investigated using tests HCA high pressure devices. properties obtained effect temperature analyzed further explored in depth. results showed that constant an overall decreasing trend increase...
In this work, interfacial reaction kinetics between α-[3-(2,3-epoxypropoxy)propyl]-ω-butyl-polydimethylsiloxane emulsion droplets with different sizes and gelatin was studied. The results of amino conversion rate determination show that the proceeded in two steps. Fluorescence spectra analysis indicates step 1 (0–2 h) should be adsorption on droplet surface. 2 (2–13 h), increased rapidly. (k2) obtained by using 2nd-order approach to model grafting kinetics. quantitative relationships among...
Abstract The issue of increasing reservoirs recovery rate in non-uniform permeable high-viscosity oil is considerably challenging, especially when the under reservoir conditions manifests its structural-mechanical properties, which characteristic Buzachi North field. Its development using water flooding method has demonstrated that even moderate uptake recoverable reserves followed by injection breakthrough to production wells. As substantiated high median permeability quotient with a broad...
Physical similarity simulation is one of the best methods for improving coal bed methane extraction efficiency, and development reasonable materials important physical testing results. This study aimed to investigate mechanical properties coal-like in a solid–gas coupled test experiment. A new type material with sand as aggregate, cement gypsum cement, silica gel adsorbent was developed by an orthogonal design method. ANOVA theoretical analysis were used sensitivity effects different content...
Determination of the wettability micron/sub-micron sized particles remains a great challenge. The present work proposes new approach to evaluate particle by measuring turbidity suspension. fine solid samples with varying were prepared hydrothermal treatment oilsands bitumen at different temperatures. particle-in-toluene suspension was determined and correlated surface chemical composition, i.e., C/(Al + Si). A good linear relationship observed between turbidity. results suggest can be used...
