Hydrate formation conditions of (H2 + CH4) binary gas mixtures in the presence tetrahydrofuran (THF) water were measured a sapphire cell using "pressure search" method. The experimental temperature ranged from 277.7 K to 288.4 K, and pressure 0.12 MPa 8.86 MPa. hydrogen composition mixture varied 0 mol % 97.85 %. THF content aqueous solution was fixed at 6
Research on gas hydrates is relevant to many industrial issues including flow assurance in oil and production transportation, exploitation of new energy deposits the form natural hydrates, storage, separation, more. The thermodynamic modeling a hydrate formation fundamental work for all research. Considering drawbacks traditional van der Waals–Platteeuw type models, Chen Guo proposed approach formation/dissociation based reaction plus adsorption two-step mechanism instead single theory....
Carbon dioxide (CO2) is often used as a process fluid in oil and gas reservoirs for enhancing the recovery. The interfacial tension of CO2 with hydrocarbons an important thermophysical property design such processes. systematical measurements equilibrium tensions systems (CO2 + single n-alkane) are currently scarce. In this work, 11 binary were measured by pendant drop method at temperatures (323.15 353.15) K. carbon number n-alkane ranged from 10 to 20. influences temperature, pressure,...
VO2(B), VO2(M), and V2O5 are the most famous compounds in vanadium oxide family. Here, their gas-sensing properties were investigated compared. VO2(B) nanoflakes first self-assembled via a hydrothermal method, then VO2(M) obtained after heat-phase transformation nitrogen air, respectively. Their microstructures evaluated using X-ray diffraction scanning transmission electron microscopies, Gas sensing measurements indicated that gas-insensitive, while both highly selective to ammonia at room...
The high efficiency separation of ethane from natural gas becomes significant due to the occurrence revolution in shale gas. Herein a new approach continuous sorption was developed using flowable zeolitic imidazolate framework-8 (ZIF-8) slurry. First, isotherms CH4 and C2H6 ZIF-8 slurry were measured at 273.15–293.15 K, corresponding desorption heats are 13 20 kJ/mol, respectively. In comparison with light oil absorption, higher solubility observed. Next, influences temperature, equilibrium...
Abstract Separation of low boiling gas mixtures is widely concerned in process industries. Now their separations heavily rely upon energy-intensive cryogenic processes. Here, we report a pseudo-absorption for separating near normal temperature. In this process, absorption-membrane-adsorption integrated by suspending suitable porous ZIF material solvent and forming selectively permeable liquid membrane around particles. Green solvents like water glycol were used to form ZIF-8 slurry tune the...
The decomposition kinetic behaviors of methane hydrates formed in 5 cm3 porous wet activated carbon were studied experimentally a closed system the temperature range 275.8-264.4 K. rates from pure free water and an aqueous solution 650 g x m(-3) sodium dodecyl sulfate (SDS) also measured for comparison. seven different cases compared. results showed that dissociate more rapidly than systems. A mathematical model was developed describing behavior below ice point based on ice-shielding...
Four reservoir samples under ultra-high-pressure and high-temperature conditions were collected from condensate gas fields in China. Constant-composition expansion tests performed to determine the phase behavior volumetric properties of fluid using an PVT test system. The compressibility factor dew-point pressure obtained at four temperatures for samples. range was 22.03 118.89 MPa. For studied, experimental results showed that decreased with increasing temperature factors increased but a...
