This paper proposed a new hydrate-based gas separation (HBGS) method especially for recovering methane from low-concentration coal mine (CMM). The main purpose of this study was to evaluate the thermodynamic promotion tetrahydrofuran (THF) on recovery CMM. Temperature and pressure conditions incipient hydrate formation (vapor−aqueous liquid−hydrate) were closely examined at various different THF concentrations (1.00, 0.10, 0.01 mol L−1) in systems (CH4−N2−O2−THF−H2O) initial operating...
In order to mitigate global warming with growing demands on fossil fuels, it is essential reduce CO2 emissions from the energy sector. Hydrate-based capture fuel gas mixture (40% CO2/60% H2) one of options carbon footprint power plants. This work employed cyclopentane (CP) as a promoter and investigated kinetic performance CP/CO2/H2 hydrate formation two different contact modes using an unstirred tank reactor (UTR) fixed bed (FBR) at 281.2 K 6.0 MPa. Repeat cycles were conducted examine...
The consumption of natural gas is great importance to optimize China's energy structure toward reduced CO2 emissions and projected increase in the next 10 years. Coalbed methane (CBM) a primary unconventional has been recognized as significant resource supplement conventional fossil fuels (oil coal) result its huge potential. It established that hydrate-based separation promising method for purification low-concentration coalbed (LCCBM). In this work, research on CH4 from LCCBM conducted by...
Hydrate-based gas separation is a potential technology for CO 2 recovery and storage, its products can be used fire prevention control in mines. Promoters are often employed to accelerate or moderate hydrate formation. In this study, experiments were performed examine the effects of different concentrations thermodynamic promoter tetrahydrofuran (THF) kinetic sodium dodecyl sulphate (SDS) on formation under stirring. The results showed that THF significantly shortens induction time hydrates;...
The occurrence forms of trace elements in coal are great significance for the clean utilization, abnormal enrichment, and recovery beneficial coal. Fushun Basin Northeast China has thick deposits which provide a good opportunity studying their geochemistry. This study aims to estimate element enrichment Paleogene seams influencing factors during deposition based on statistical geochemical analyses. Compared with world hard coals, coals feature Ga Sb (CC > 5), slight V, Cr, Co, Ni, As, Rb,...
The depressurization method is considered to be one of the most promising gas hydrate extraction methods. With use a decomposition simulation test system, four gradient modes and intervals were under two saturation conditions, namely, 24–35 46–64%, simulate borehole pressure salinity in mining location. findings indicate that duration influenced by level saturation, with higher resulting greater decrease time compared lower levels when subjected decline 3 MPa. Specifically, times Run 2–2a,...
Abstract To analyze the relationship between macro and meso parameters of gas hydrate bearing coal (GHBC) to calibrate meso-parameters, numerical tests were conducted simulate laboratory triaxial compression by PFC3D, with parallel bond model employed as particle contact constitutive model. First, twenty simulation quantify macro–meso parameters. Then, nine orthogonal performed using four meso-mechanical in a three-level evaluate sensitivity Furthermore, calibration method meso-parameters...
Based on the previous research energy absorption of foam metal materials with different structures, a composite blast-resistant energy-absorbing material flexible core layer was designed. The is composed three fiber (carbon fiber, aramid and glass fiber) as foamed iron–nickel front rear panels. characteristics were tested using self-built gas explosion tube network experimental platform, effects combinations analyzed. purpose this paper to evaluate performance designed layers. results show...
Coal mine gas (CMG) is a form of unconventional natural and its reserves are abundant. However, large proportion coal cannot be used owing to the low concentration extraction gas. The hydrate-based method can for separation recovery methane from To devise an economic efficient using hydrates, dry water (DW) was as carrier under conditions in which initial pressure fixed at 10 MPa temperature set 274 K. On this basis, repeated hydrate experiments were carried out three times. A pure-water...
Hydrate-based gas storage holds a huge potential to become promising technology in the future, provided that conditions are moderate enough. Tetrahydrofuran (THF), widely known promoter, is used this study understand its effect on hydrate phase equilibrium and cage occupancies thereafter. Here, we present fugacity-based thermodynamic model three-phase liquid-hydrate-vapor (L-H-V) equilibria of CH4 pure water (sI hydrate) 0.48–5.56 mol % THF solutions (sII hydrate). The uses vdW-P theory for...
