“…Apart from experimental studies on gas hydrates, Indian researchers have put efforts into modeling thermodynamics as well as kinetics of hydrate formation and dissociation. Following is a brief account of these modeling studies; however, reviews of gas hydrate models in hydrate nucleation, 172 hydrate growth, 173 hydrate dissociation, 174 and hydrate equilibrium 175 can be found elsewhere in the literature.…”

Gas hydrates have been an intense area of research during the past two decadesowing to their characteristic advantages and utilization potential in several applications. Methane hydrates carve a niche among gas hydrates owing to their immense energy potentialthey are available as an energy resource as well as catering to a plethora of applications including energy (gas) storage, gas separation/enrichment, etc. This Review attempts to put forth the status of gas hydrate research in Indiait includes a summary of exploration and research efforts by several agencies and academic groups in India. The National Gas Hydrate Program (NGHP), initiated in 1997, has conducted two successful expeditions, NGHP-01 and NGHP-02, in 2006 and 2015, respectively. Salient findings and analysis results from these expeditions along with fostered international collaboration are presented as well. Research efforts put forth by various academic groups in India are reviewed and discussed based on hydrate applications. Future directions for gas hydrate research in India are also outlined in this Review.

“…The water molecules are referred to as the host molecules, and the guest molecules are the gas contained within the host molecules. The crystals are stabilized with the result of van der Waals forces, where no bonding occurs between the host and guest molecules as the guest molecules can freely rotate in the water cage. − …”

This work presents the effect of hydrogen sulfide gas on the phase behavior of both methane gas hydrate formation and CO 2 gas hydrate formation. For this, the thermodynamic equilibrium conditions for various gas mixtures containing CH 4 /H 2 S and CO 2 / H 2 S are initially found by simulation using PVTSim software. These simulated results are compared using an experimental approach and the available literature. Then, the thermodynamic equilibrium conditions generated by simulation are used for generating Hydrate Liquid−Vapor-Equilibrium (HLVE) curves to understand the phase behavior of gases. Further, the effect of hydrogen sulfide on the thermodynamic stability of methane and carbon dioxide hydrates was studied. It was clearly observed from the results that an increase in H 2 S composition in the gas mixture decreases the stability of CH 4 and CO 2 hydrates.

A prediction model is developed by means of artificial neural networks (ANNs) to determine the gas hydrate formation kinetics in multiphase gas dominant pipelines with crude oil. Experiments are conducted to determine the rate of formation and reaction kinetics of hydrates formation in multiphase systems. Based on the results, an artificial intelligence model is proposed to predict the gas hydrate formation rate in multiphase transmission pipelines. Two ANN models are suggested with single-layer perceptron (SLP) and multilayer perceptron (MLP). The MLP shows more accurate prediction when compared to SLP. The models were predicted accurately with high prediction accuracy both for the pure and multiphase systems.
