“…Second, temperature and pressure conditions on gas and oil pipeline walls facilitate formation of natural gas hydrates which are built on pipe walls resulting in pipe capacity reduction and blocking. Natural gas hydrates can be also treated as possible climate change factor because sudden methane hydrate dissociation on the ocean bottom can result in methane outburst to atmosphere and, together with high greenhouse activity, contribute to global warming [8,9].…”

The processes of nucleation and growth of methane hydrate in a highly supercooled two-phase "methane-water" system obtained using various cooling protocols are considered. It has been shown that, at sufficiently high cooling rates, crystalline forms of methane hydrate can still form in the system. It was found that, at a cooling rate of γ=1.0 K/ps, the process of nucleation and growth of gas hydrate was observed in all independent molecular dynamics iterations, while at a cooling rate of γ=10.0 K/ps, no nucleation event was observed in ~26.7% of numerical experiments. It was found that with an increase in the cooling rate of the system, an increase in the average time scale of nucleation tauc and a decrease in the critical size of the nucleus nc are observed. It is shown that at a sufficiently deep level of supercooling of the system, the scenario of homogeneous crystalline nucleation is realized at the initial stage of the phase transition. Keywords: molecular dynamics, crystallization, methane hydrate.

“…Во-вторых, термобарические условия на стенках газои нефтепроводов соответствуют условиям образования гидратов природных газов, которые нарастают на стенках труб, что ведет к снижению их пропускной способности и закупориванию. Природные газовые гидраты также могут рассматриваться как фактор возможного изменения климата, поскольку внезапная диссоциация гидрата метана на дне океана может привести к резкому выбросу метана в атмосферу, что в совокупности с высокой парниковой активностью метана, может внести большой вклад в глобальное потепление [8,9].…”

The processes of nucleation and growth of methane hydrate in a highly supercooled two-phase methane–water system obtained using various cooling protocols are considered.

The global energy content of methane occurring in the gas hydrate form is immense. Understanding the fundamental of hydrate phenomena is crucial in predicting its formation, growth, and decomposition dynamics. In this contribution, at first, we propose a generalized formulation of sI hydrate formation and decomposition targeting to employ for (i) single and mixed guests, (ii) pure and salt waters, and (iii) reservoir with and without porous particles. This framework introduces the nth order reaction (phase transformation) and theoretically addresses various concerns, including the surface renewal of porous particles and the existence of tension at the interface between the guest gas and liquid water, arising during the formation or decomposition of gas hydrates. In the next phase, we develop the nondominated sorting genetic algorithm-II (NSGA-II) to optimize the model performance in predicting the experimental data. Such a global optimization strategy is proposed for the first time in the gas hydrate area. Validating this optimal model with a wide variety of data sets reported for the formation, growth, and decomposition of methane and carbon dioxide gas hydrates at reservoir mimicking conditions, the model is subsequently compared to show its superiority over a couple of latest models. Further, we applied the developed optimization strategy to the five existing hydrate models and showed that the modified optimal forms of those five models outperform their original forms. The performance improvement is quantified here by the percent absolute average relative deviation (%AARD). Based on the promising performance achieved by this generalized formulation, it is recommended to use it for system design, operation, optimization, and troubleshooting.
