“…Study on inhibitors shows that, TDIs alone only effective at certain dosage level and condition. Thus, suggested that in practice, it is better to use the TDIs together with the KHIs as it improves performance and efficiency [9,12,15].…”

Deepwater fields are characterized by extreme low temperature and high pressure, houses huge potential amount of hydrated gas. However, deepwater is associated with scenarios such as, costly structures, scattered wells, and exploration at even further and deeper locations. Nevertheless, the need for a cleaner source of energy has triggered the oil and gas industries to increase their exploration and production activities towards deep seas. However, such hostile environment is favorable for solid deposits such as hydrate formations, in which has become a major deepwater flow assurance concern. The tremendous shifting of oil and gas activities from shallow water to deepwater ads-on the flow assurance challenges, yet, has pooled numerous types of hydrate prevention methods in many ways and even has raised the idea of changing the hydrate paradigm. Over the last decade, even though there are few compilations of current practices in hydrate prevention methods are available in literature, but these are addressed within the specific categories. The objective of this paper is to review and distinguish possibly all types of existing hydrate prevention methods. It is hoped that the review would serve as an industrial application in a form of quick reference in identifying appropriate methods for hydrate prevention. The review shall be based on past and current practices and reflects a more inter-disciplinary approach in hydrate prevention.

“…Although, the thermodynamic inhibitors including alcohols, glycols and electrolytes effectively cause to inhibit the formation of gas hydrates, their large concentrations are needed (10-50 wt.%) with high cost [8,28,29,40]. The low dosage kinetic inhibitors (LDHIs) including anti-agglomerates (AAs) and kinetic hydrate inhibitors (KHIs) as a new group of inhibitors have been proposed to prevent hydrate formation so that these inhibitors not only don't change the thermodynamic conditions of gas hydrate formation but they are also able to delay hydrate nucleation and slow down the rate of hydrate growth [20,40]. Many works have been carried out to applying LDHIs [2,8,9,20,22,[26][27][28][29]48].…”

On the other hand, recently the gas hydrates have been considered as a new tool for storage and transport of natural gas [43].…”

“…A cooling bath which could able to maintain the temperature with the accuracy of ±0.01 K from the set point was also used. A gas booster system was used to compress the gases to the pressures required in this research 21,22 . The RTDs, pressure transducers and gas volume meter were all connected to a data acquisition system, which was inserted into the expansion slots of a computer.…”

The purpose of this study was to investigate the natural gas hydrate promotion capabilities of the hydrotrope Toluene Sulfonic Acid (TSA) isomers as an additive. The capabilities of TSA isomers were measured with different concentrations. The optimum additive concentration for hydrate formation was determined for the given pressure, temperature, mixing condition, and cooling time. The natural gas hydrate promotability of para-TSA was found to be 20% and 35% more than meta-TSA and ortho-TSA respectively at the optimum concentration. Beyond the optimum TSA concentration, the hydrate formation declined as the ice formation reduced the overall gas-to-water volume ratio in the hydrates
