Abstract Clathrate hydrate-based desalination (HyDesal) is a promising desalination technology but it is energy intensive. Developing strategies to reduce the high energy consumption of HyDesal process is necessary for its industrial application. The need for refrigeration requirement for the operation of HyDesal can be offset by LNG cold exergy to reduce its energy consumption. However, the LNG cold exergy utilization efficiency is low due to the large temperature difference between LNG and sea...

Abstract The energy demand for space cooling has more than tripled for the past thirty years and was responsible for emissions of about 1 Gt CO2 annually. The ever-increasing energy demand for cooling has posed a demanding question on improving the energy efficiency of cooling processes. On the other hand, with the growing global demand on LNG, cold energy released from LNG terminals has been growing to a historical high at 6.6 × 1014 kJ in 2017. Thus, there is a strong need to search for a suit...

Methane hydrates in nature are considered as a future energy resource for natural gas due to their abundance in nature. The presence of all three structures of clathrate hydrates in the nature have been reported. Structural transition in clathrate hydrates in particular with regards to sH hydrates and the influence of large guest molecules is still not well understood. In the current work, we synthesize mixed hydrate of CO2 & CH4 mixture in presence of sH formers, neo-hexane (NH) and tert-butylm...

Abstract Knowledge of the thermophysical properties of methane hydrate-bearing sediments (MHBS) plays a critical role in the evaluation of fluid production potential from gas hydrate accumulations in geologic media. The process of estimating the values of key flow and transport parameters related to MHBS is of great importance. In this paper, we developed an integrated optimization workflow by integrating a global optimization algorithm, specifically particle swarm optimization (PSO) with the TO...

Storing natural gas in the form of clathrate hydrates (termed as Solidified Natural Gas, SNG) is highly advantageous as it is non-explosive, environmentally benign and offers a relatively compact mode of natural gas storage with high volumetric storage capacity. Here for the first time, we demonstrate rapid methane storage in seawater and saline water (1.1 mol% NaCl solution) via clathrate hydrates aided by 5.56 mol% THF in a simple quiescent reactor configuration. We report extremely fast forma...
