“…Gas hydrates have significant applications, as they are known as potential energy source that will replace fossil fuel [7]. In addition, they can be applied in other areas such as, gas storage and transportation [8,9], sea water desalination [10] and CO 2 capture and sequestration [11]. On the other hand, gas hydrate causes a lot of flow assurance problems.…”

Background:Gas hydrates are considered as a major threat to the oil and gas flow assurance industry. At high pressure and low temperature conditions, gas hydrates form in pipelines and production facilities leading to pipeline blockages, high removal cost, environmental hazards and loss of lives. For a successful prevention of gas hydrate formation, predicting the hydrate formation phase boundary of hydrocarbon fluid composition becomes very necessary. Objective and Method:In this study, computer simulation software called PVTSim was used to predict hydrate formation phase boundary of synthetic natural gas composition of the Keta basin of Ghana at pressure and temperature ranges of 43.09 bar -350 bar and 12.87 °C -27.29°Crespectively. The effect of changes in natural gas composition (N 2 and H 2 S) and the presence of four commonly used thermodynamic gas hydrate inhibitors (methanol, ethanol, diethylene glycol and monoethylene glycol) on the hydrate formation phase boundary is also discussed. Prior to the study, the accuracy of PVTSim was validated with the hydrate formation phase data in literature. Results and Conclusion:Results suggested that the hydrate formation phase boundary decreased with increasing N 2 composition and increased with increasing H 2 S composition, suggesting that, the presence of H 2 S increases the threat of hydrate formation. However, a reduction in hydrate formation threat was observed in the presence of all four commonly used gas hydrate thermodynamic inhibitors with methanol demonstrating the highest inhibition effect.

“…Equilibrium pressures of mixed-gas hydrates are also moderated by these hydrate formation promoters (Figure 2). Generally, there are two types of hydrate formation promoters: chemical additives for gas hydrate that have no effect on structures of the water cages (e.g., tetrahydrofuran, cyclopentane, and anionic/non-ionic surfactants), and SC types such as TBA salts that form SC [24,25,41]. These additives reduce hydrate formation pressures.…”

This paper proposes an innovative CO 2 enrichment system for crop production under a controlled greenhouse environment by means of tetra-n-butylammonium bromide (TBAB) + CO 2 semi-clathrate hydrate (SC). In this system, CO 2 is captured directly from exhaust gas from a combustion heater at night, which can be used for stimulating photosynthesis of crops in greenhouses during daytime. Although the gas capacity of TBAB + CO 2 SC is less than that of CO 2 gas hydrate, it is shown that TBAB + CO 2 SC can store CO 2 for CO 2 enrichment in crop production even under moderate pressure conditions (<1.0 MPa) at 283 K.

“…A self-contained storage vessel consisting of a low-temperature-grade carbon steel coded vessel and insulation and control systems equipped with approved class valves, piping, and fittings was considered. So far, CO2 separation and capture from waste gas by means of CO2 hydrate has been proposed [8][9][10]. Figure 7 shows the CO2 hydrate production system [11].…”

A Feasibility Study on Hydrate-Based Technology for Transporting CO2 from Industrial to Agricultural Areas

Climate change caused by global warming has become a serious issue in recent years. The main purpose of this study was to evaluate the effectiveness of the above system to quantitatively supply CO2 or CO2 hydrate from industrial to agricultural areas. In this analysis, several transportation methods, namely, truck, hydrate tank lorry, and pipeline, were considered. According to this analysis, the total CO2 supply costs including transportation ranged from 15 to 25 yen/kg-CO2 when the transportation distance was 50 km or less. The cost of the hydrate-based method increased with the transport distance in contrast to the liquefied CO2 approach. However, the technology of supplying CO2 hydrate had merit by using a local cooling technique for cooling specific parts of agricultural products.
