Preparation of water soluble poly(aniline) and its gas-sensitivity

Green Chemistry, 2005
Water soluble poly(aniline) was prepared using the chemical oxide method by adding a small amount of poly(sodium-p-styrenesulfonate). Poly(aniline) composite film on interdigital electrodes of carbon was formed via the spin-coating approach. After pretreatment of exposure in an alkalescence atmosphere and desorption with high-purity N2, the film showed

Microbial degradation of the water-soluble fraction of gas oil—I

Water Research, 1978
Abstract The microbial degradation of the water-soluble components of gas oil was measured both qualitatively and quantitatively. The mixed autochthonous flora in clean ground water served as the inoculum in continuous percolation experiments. Concentration gradients of individual compounds as well as of DOC were measured as a function of the ...

The determination of chromium in water-soluble polymers by gas chromatography

Analytica Chimica Acta, 1981
Abstract Water-soluble polymers have found increasing use in the areas of water treatment, paper production and oil recovery, and the determination of heavy metals in such materials is important from an environmental standpoint. Heavy metal contamination could result from redox catalysts in the polymerization system, raw materials or stainless steel ...

Study of gas-water properties under high temperature and pressure for water-soluble gas reservoirs

Toxicological & Environmental Chemistry, 2015
The physical properties of gas and water are important in usage of gas reservoirs with water and water-soluble gas reservoirs. According to the Petroleum and Natural Gas Industry Standards SY/T5542-2009 of the People's Republic of China, by applying the crude oil multistage degassing method from the “Test Method for Reservoir fluid Physical Properties”

Numerical simulation of produced water reinjection technology for water-soluble gas recovery

Journal of Natural Gas Science and Engineering, 2014
Abstract Water-soluble gas reservoir refers to those unconventional reservoirs composed of methane mostly, which dissolved in over-pressure and high-temperature groundwater. The Paleogene Wenchang and Enping Formations of the Huizhou Sag are major source rocks that generate significant quantities of gas and the sandstone reservoirs are varying from ...

Development of water leak detection method in fusion reactors using water-soluble gas

Fusion Engineering and Design, 2008
Abstract A water leak detection method using krypton (Kr) as a water-soluble tracer has been proposed for fusion reactors with fully circulating the in-vessel cooling water. This method was targeted for applying to the International Thermonuclear Experimental Reactor (ITER), and the 10−3 Pa m3/s order of water leak valves were fabricated and ...

Gas-Phase Conversion of Oxide Phases of Lanthanides and Uranium to Water-Soluble Compounds

Radiochemistry, 2020
Gas-phase conversion to water-soluble compounds of individual rare-earth element (REE) (La, Ce, Pr, Nd, Sm, Eu, Dy, Ho, Er, Tm, Lu) oxides and oxide systems (U,Ce)Ox and (U,Nd)Ox in the atmospheres HNO3 (vapor)–air and NOx–H2O (vapor)–air was examined. It was shown that water-soluble compounds are formed in the gas-phase conversion of REE oxides in the

Effect of Stress-Sensitive Permeability and Porosity on Production Performance in Water-Soluble Gas Reservoirs

Journal of Energy Resources Technology, 2021
Abstract Water-soluble gas reservoirs have the characteristics of high temperature and high pressure (HTHP) and experience obvious pressure-sensitive effects during the production process. Therefore, the influences of formation water and dissolved natural gas in formation water on water-soluble gas reservoirs are different from ...

Experimental and theoretical study on water solubility of carbon dioxide in oil and gas displacement

Journal of Petroleum Science and Engineering, 2021
Abstract The emission of greenhouse gas carbon dioxide causes the global temperature to rise year by year. A possible method for CO2 storage and emission reduction is to use it to displace oil and gas. Solubility of CO2 in water is key to replace oil and gas.
