Solubility Measurement of Natural Gas in Reservoir Formation Water under (333.2 to 393.2) K and (15.0 to 43.6) MPa

Journal of Chemical & Engineering Data (2011)

Xu-Long Tang Zhenxue Jiang Feng‐Guang Li Chang-Yu Sun Guangjin Chen

The solubility of five groups of natural gas in reservoir formation water was measured under (333.2 to 393.2) K and (15.0 to 43.6) MPa. The formation water and corresponding natural gas were sampled in situ from a China oilfield. The range of total dissolved solids (TDS) of the reservoir formation water samples is from (8744 to 80634) mg·kg−1. The mole fraction of methane in natural gas ranges from 0.7575 to 0.9449. The experimental results show that, with the increase of temperature and pressure, the solubility of natural gas in formation water goes through a minimum value under the experimental conditions. The solubility of natural gas in formation water was also influenced by a composition of gas phase and TDS of liquid phase. The salt effect becomes more significant in the high-pressure region.

Vapor−Hydrate Equilibria for the Methane + Hydrogen + Tetrahydrofuran + Water System

Journal of Chemical & Engineering Data (2008)

Xiulin Wang Chang‐Yu Sun Lan-Ying Yang Qin-Lan Ma Xu-Long Tang

Vapor−hydrate equilibria data for the methane + hydrogen + tetrahydrofuran + water system were obtained using the sapphire cell device. The influence of temperature, pressure, initial gas−liquid volume ratio, and the mole fraction of tetrahydrofuran was investigated to evaluate the separation efficiency by forming hydrate at different operating conditions. The experimental results show that decreasing operating temperature or the initial gas−liquid volume ratio and increasing operating pressure or initial tetrahydrofuran mole fraction will be effective to increase the content of hydrogen in the vapor phase. But their influence on the recovery degree of hydrogen in the vapor phase and the operating cost should also be taken into account synthetically when designing a separation process.

Affect of Pressure on Photoreduction of CO2 to Acetaldehyde in Aqueous Suspensions of TiO2

International Conference on Energy and Environment Technology (2009)

Xu-Long Tang Guangjin Chen Haili Liu Jing Fang

A new equipment which bears high pressure was designed for heterogeneous photocatalysis. Acetaldehyde was the major product on suspend nano anatase titanium dioxide in liquid phase .The yield of acetaldehyde was increased with an increase in the pressure of CO ₂ at first, then decreased sharply with further increase in the pressure after an optimum pressure. What's more, the optimum pressures were varied against different temperatures. The yield of acetaldehyde could increased by as much as 3.51 times.
