“…Further details on the model development and assumptions can be found in the literature. 14,15,39,41,46,92 The models' errors as shown in Table 4 are below 8% and ±0.6 K for CH 4 and CO 2 hydrates, which are acceptable and agree well with the experimental methods. According to Zare et al, 41 the prediction performances of the PC-SAFT/UNIQUAC model are better than the eCSW model.…”

Ionis liquids (ILs) are promising novel thermodynamic gas hydrate inhibitors (THIs) that have gained an ongoing experimental and modeling research prospect over a decade. In view of this, the path to developing desirable ionic liquids THIs depends on understanding the state-of-the-art methods of ILs hydrate inhibition impacts and factors that influence their performance. This review provides a holistic summary of the use of ILs as THIs. Almost all the available thermodynamic hydrate inhibition data of different gas systems in the presence of ILs at varying concentrations were critically reviewed and analyzed. Also, all ILs hydrate-related phase behavior modeling studies and their prediction accuracies are discussed in this work. The hydrate phase boundary inhibition effects of each IL are provided alongside factors that affect their inhibition performance. The study showed that IL cations, anions, and chain length characteristics control their hydrate inhibition impacts. By far, a narrow hydrate suppression temperature window below 3 K at 10 wt % IL concentration has been achieved with accurate predictions using various models. This narrow THI performance window could be enhanced by exploring novel IL families with low molecular weights, well-optimized cation–anion interactions, and active hydrogen bonding interactive functionalities. The findings presented in this work are relevant for future IL-related breakthrough research in hydrate inhibition technologies.

“…Hydrate deposition, generally including hydrate implantation deposition, tube wall adhesion, and tube wall film growth, is an important cause of hydrate blockage . At present, scholars have carried out a large number of experimental studies on the formation and deposition of hydrates. − Liang et al used X-ray computed tomography to obtain the three-dimensional morphology and parameters of the hydrate shell over time and, from this, the mass transfer characteristics of hydrate molecules and guest molecules during the hydrate formation process. Ravichandran et al proposed a pseudo-steady-state mechanical model to predict the amount of hydrate deposition in a stratified flow at a given time and developed a hydrate simulator through the model to predict the thickness of the hydrate deposition layer.…”

With the exploration and development of natural gas gradually extended to the deep sea, low-temperature and high-pressure environmental conditions and long-distance transportation make flow assurance engineers have to consider the impact of the formation and blockage of natural gas hydrates on the flow stability in the pipeline. Therefore, an inadequate understanding of the hydrate formation and plugging mechanism in a gas-rich (gas-dominant) system has become a serious obstacle to the prediction of hydrate formation and implementation of blocking prevention and control strategies. To this end, this review has conducted a comprehensive review of recent experimental investigations into hydrate formation and blockage in gas-rich systems in flow loop devices, and the physical models to characterize the clogging mechanism of hydrates established by previous scholars were summarized. In addition, the three flow patterns of the gas-rich system were divided, and the hydrate deposition mechanism corresponding to each flow pattern and the prediction model of the deposition layer thickness was summarized. Eventually, the natural gas hydrate mitigation and prophylaxis and restrain strategies used in the process of deep-sea natural gas transportation were summarized, including advantages and disadvantages of natural gas dehydration, changing the gas flow rate, and adding chemical inhibitors. The advantages and feasibility of an under-inhibited system and changing the gas flow rate for the management and prevention of hydrate blockage were emphasized. The conclusion can improve the safety index of natural gas development and transportation operations and reduce the output loss of natural gas energy and economic loss of hydrate anti-blocking.

“…Because of their distinctive physical and chemical properties, such as high thermal stability, negligible vapor pressure, biodegradability, nonvolatility, noncorrosiveness, and inflammability, ILs have received a lot of attention . As a result, ILs are used in biocatalytic transformations, chemical synthesis, electrochemistry, separation and analytical science, catalysis, biomass conversion, desulfurization, scale removal, gas hydrate, carbon capture, crude oil dissolution, and oil/water IFT reduction. ,− …”
