Impact of Gas–Condensate Composition and Interfacial Tension on Oil-Repellency Strength of Wettability Modifiers

24.10.2014 | J. Fahimpour; M. Jamiolahmady, Energy & Fuels, 2014

Productivity of gas–condensate wells can significantly be declined as the condensate bank evolves around the wellbore. Wettability alteration of formation minerals from strongly liquid-wet to intermediate gas-wet conditions using liquid-repellent fluorinated chemicals has shown promising results ...

Digital Transfer Growth of Patterned 2D Metal Chalcogenides by Confined Nanoparticle Evaporation

24.10.2014 | Masoud Mahjouri-Samani; Mengkun Tian; Kai Wang; Abdelaziz Boulesbaa; Christopher M. Rouleau; Alexander A. Puretzky; ..., ACS Nano, 2014

Developing methods for the facile synthesis of two-dimensional (2D) metal chalcogenides and other layered materials is crucial for emerging applications in functional devices. Controlling the stoichiometry, number of the layers, crystallite size, growth location, and areal uniformity is ...

Novel Microelectrode-Based Online System for Monitoring N2O Gas Emissions during Wastewater Treatment

23.10.2014 | Ricardo Marques; Adrian Oehmen; Maite Pijuan, Environmental Science & Technology, 2014

Clark-type nitrous oxide (N2O) microelectrodes are commonly used for measuring dissolved N2O levels, but have not previously been tested for gas-phase applications, where the N2O emitted from wastewater systems can be directly quantified. In this study, N2O microelectrodes were tested and ...

Experimental Measurement and Thermodynamic Modeling of Hydrate Dissociation Conditions for the Argon + TBAB + Water System

23.10.2014 | Saeedeh Babaee; Hamed Hashemi; Amir H. Mohammadi; Paramespri Naidoo; Deresh Ramjugernath, Journal of Chemical & Engineering Data, 2014

Gas hydrate (clathrate hydrate) dissociation data at low to moderate pressures are necessary for practical applications, e.g., for gas separation. However, it is often known or recognized that the separation conditions encountered exist at high pressures and low temperatures. One solution to this ...

Effects of Steam on the Release of Potassium, Chlorine, and Sulfur during Char Conversion, Investigated under Dual-Fluidized-Bed Gasification Conditions

22.10.2014 | Placid A. Tchoffor; Kent O. Davidsson; Henrik Thunman, Energy & Fuels, 2014

The corrosion and fouling of heat-transfer surfaces and the agglomeration of bed materials in fluidized beds are some of the ash-related problems caused by the transformation and release to the gas phase of ash-forming elements from biomass during thermochemical conversion processes. The ...

Monitoring Solid Oxide CO2 Capture Sorbents in Action

21.10.2014 | Christopher J. Keturakis, Fan Ni, Michelle Spicer, Michael G. Beaver, Hugo S. Caram, Israel E. Wachs, ChemSusChem, 2014

Abstract The separation, capture, and storage of CO2, the major greenhouse gas, from industrial gas streams has received considerable attention in recent years because of concerns about environmental effects of increasing CO2 concentration in the atmosphere. An emerging area of research ...

Investigation of Ethane Hydrate Formation during Isobaric and Isothermal Conditions

21.10.2014 | M. Naseh; V. Mohebbi; R. M. Behbahani, Journal of Chemical & Engineering Data, 2014

In this work, we studied the mass transfer phenomenon of ethane during hydrate formation. Fifteen different tests were conducted over temperature range of (273.15 to 282.15) K and three levels of pressure at each temperature. A mass transfer approach has been consumed and was evaluated with ...

Pyrolysis of Lignite with Internal Recycling and Conversion of Oil

20.10.2014 | Yong Huang; Hajime Sakamoto; Shinji Kudo; Koyo Norinaga; Jun-ichiro Hayashi, Energy & Fuels, 2014

The present authors studied pyrolysis of lignite with internal recycling of a heavier portion of the liquid product (oil), employing a reactor that experimentally simulated continuous pyrolysis in a gas–solid countercurrent moving-bed reactor. The lignite particles traveled through the isothermal ...
