Due to the large-scale infrastructure construction and environmental protection pressure in China, demanded cement is short supply price rising, overcapacity of silica fume has caused its fall, thus replacing paste by could achieve better economic benefits. In this study, (SF) with SiO2 content 86.3% high purity (HSF) 96% were used replace different proportions. The effects adding SF or HSF on workability fresh concrete, mechanical properties microstructure hardened concrete investigated....
In order to reduce the emission of coal bed methane mixed with air (can be regarded as a CH4 and N2 mixture), which will helpful adequately utilize natural resources protect environment, separation via hydrate formation in tetra-n-butylammonium bromide (TBAB) solution was systematically studied this work. The CH4−N2 conditions were determined TBAB first, then experiments carried out TBAB−sodium dodecyl sulfate (SDS) solution, respectively. experimental results show that form much easier...
Tetra-n-butyl ammonium bromide (TBAB) is most-widely used as a hydrate promoter in the separation of flue gases and CO2 sequestration. Because complicacy semiclathrate formed by TBAB aqueous solution gases, few researchers have investigated thermodynamic modeling phase equilibria hydrates. In this work, CH4–N2 dissociation conditions were determined first, then model for gas proposed Chen Guo was extended hydrates mixtures solution. The Patel-Teja equation state (PT EoS) calculation fugacity...
Because of the technology limitation and safety requirement, a large amount air-mixed coal bed methane is released directly to atmosphere. It leads severe waste resources exacerbates greenhouse effect. This work tries alleviate this problem by separating CH4 from mixture N2 via hydrate separation method. Several experiments were systematically carried out in 6 mol % tetrahydrofuran (THF) solution separate CH4/N2 gas mixtures containing 4.90 71.23 CH4. The results that THF can significantly...
During oil recovery process, the equilibrium state of asphaltene–oil solution system and colloidal in porous media is altered, which could cause asphaltene to precipitate from crude rock pores. This severely results alteration wettability, permeability, porosity formation damages reservoir formation. Nanoparticles have recently been considered as effective inhibitors. Several experimental works were carried out study impact nanoparticles on precipitation. The majority these studies performed...
