High-Performance Kinetic Hydrate Inhibition with Poly(N-isopropyl methacrylamide) and Triisopentylamine Oxide?Surprising Concentration-Dependent Results

Radhakanta Ghosh et al.

Summary: Kinetic hydrate inhibitors (KHIs) are used to prevent gas hydrates deposition and their performance is limited by subcooling and other factors. Poly(N-isopropyl methacrylamide) (PNIPMAm) blended with triisopentylamine oxide (TiPeAO) showed exceptional KHI performance. The performance decreased at higher concentrations, possibly due to polymer and amine oxide aggregation. Overdosing of components can have detrimental effects on KHI performance.

Pushing the Known Performance Envelope of Kinetic Hydrate Inhibitors-Powerful Synergy of Trialkylamine Oxides with Acrylamide-based Polymers

Radhakanta Ghosh et al.

Summary: This study demonstrates that the addition of alkyl amine oxide synergists can enhance the performance of PNIPMAm as a kinetic hydrate inhibitor. However, overdosing the polymer or synergist in the blends can worsen the inhibitor's performance, possibly due to unwanted interaction between the two chemicals.

5-Methyl-3-vinyl-2-oxazolidinone-Investigations of a New Monomer for Kinetic Hydrate Inhibitor Polymers

Malcolm A. Kelland et al.

Summary: Kinetic hydrate inhibitors (KHIs) are polymers used to prevent gas hydrate plugging of oil and gas production flow lines. In this study, the KHI performance of polymers based on the vinylic monomer VMOX was investigated. PVMOX-2.4k showed better performance than PVP or PiPOx, but not as good as PVCap. Isobutyl glycol ether enhanced the KHI performance of PVMOX, and increasing concentration improved the performance but not as much as some of the best amide-based KHI polymers. A copolymer of VMOX with N-vinylcaprolactam performed better than the PVMOX homopolymer.

Non-Amide Polymers as Kinetic Hydrate Inhibitors-Maleic Acid/Alkyl Acrylate Copolymers and the Effect of pH on Performance

Janronel Pomicpic et al.

Summary: Kinetic hydrate inhibitors (KHIs) are chemicals used to prevent natural gas hydrate formation in oil and gas production flow lines, typically consisting of water-soluble polymers. Researchers explored maleic acid/alkyl acrylate copolymers as potential low-cost KHIs and found that they performed well under high pH conditions.

Review of Kinetic Hydrate Inhibitors Based on Cyclic Amides and Effect of Various Synergists

Ankur Singh et al.

Summary: This review comprehensively discusses the performance and influencing factors of cyclic-amide-based kinetic hydrate inhibitors, presenting the top ten KHIs with the highest performance in terms of cloud point and induction time. The synergistic effects of guanidinium salts and phosphonium salts on these KHIs are also highlighted.

The delay of gas hydrate formation by kinetic inhibitors

Vincent W. S. Lim et al.

Summary: The study found that kinetic hydrate inhibitor (KHI) can delay the nucleation of hydrates, increase the nucleation work required to form critical nuclei, and increase the effective number of sites where nucleation could occur.

Powerful Synergy of Acetylenic Diol Surfactants with Kinetic Hydrate Inhibitor Polymers-Choosing the Correct Synergist Aqueous Solubility

Malcolm A. Kelland et al.

Summary: The performance of injected kinetic hydrate inhibitor (KHI) polymer solutions can be significantly enhanced by optimizing the polymer solvent system. Experimental results demonstrate excellent KHI synergism between low-foaming acetylenic diol gemini surfactants and certain polymers, with a decrease in synergistic performance observed when a specific model liquid hydrocarbon phase is introduced.
