Mechanisms of synergistic inhibition of NaCl and glycine mixtures on methane hydrate formation: Experimental and molecular dynamic simulation

Jianlong Wang et al.

Summary: The effects of NaCl-glycine mixture on methane hydrate formation and the underlying mechanisms were investigated. It was found that NaCl can inhibit hydrate growth by changing the phase equilibrium conditions, while glycine possesses both kinetic and thermodynamic inhibition capabilities. NaCl reduces the solubility of methane and glycine promotes the formation of methane nano bubbles, leading to hindered hydrate growth. A mixture of 5.0 wt% glycine and 3.5 wt% NaCl showed a significantly longer induction time and a reduced methane consumption rate.

Molecular dynamics simulation to explore the synergistic inhibition effect of kinetic and thermodynamic hydrate inhibitors

Zhi Li et al.

Summary: The synergistic mechanism of KHIs and THIs in preventing methane hydrate formation involves three stages, with gas adsorption playing a dominant role. The addition of THIs to solutions containing KHIs enhances methane attraction and weakens the driving force for hydrate formation. It is suggested that the methane adsorption capacity of hybrid inhibitors should be considered in future development.

Natural Pectin and Commercial Luvicap-Bio as Green Kinetic Hydrate Inhibitors: A Comparative Evaluation by Crystal Growth Inhibition Methods

Morteza Aminnaji et al.

Summary: Low dosage kinetic hydrate inhibitors (KHIs) are an effective method for preventing solid gas hydrate plug formation in the oil and gas industry. Efforts have been made to develop environmentally friendly KHIs due to concerns around the non-biodegradability of traditional chemistries. Natural pectin has been identified as a potential green KHI with good hydrate inhibition properties. This study compared the performance of food grade apple pectin and the commercial biodegradable KHI polymer Luvicap Bio using crystal growth inhibition methods. Results show that Luvicap Bio offers significant inhibition to high subcoolings, while pectin only shows some anti-nucleation properties.
