Dimethyl sulfoxide as a novel thermodynamic inhibitor of carbon dioxide hydrate formation

Anton P. Semenov et al.

Summary: This paper investigates the potential of dimethyl sulfoxide (DMSO) as an inhibitor of gas hydrates. Equilibrium conditions of CO2 hydrates were measured at different temperatures and DMSO concentrations, revealing that DMSO reduces the thermodynamic stability of CO2 hydrate and exhibits stronger inhibition activity in water solution compared to lower alcohols. The study also demonstrates the thermodynamic coherence of the new hydrate equilibrium data and identifies the presence of sI hydrate, crystalline ice Ih, and solid CO2 phases. Overall, DMSO can be considered an effective thermodynamic inhibitor for CO2 hydrate formation, surpassing the activity of alcohol THIs within a specific range.

The pursuit of a more powerful thermodynamic hydrate inhibitor than methanol. Dimethyl sulfoxide as a case study

Anton P. Semenov et al.

Summary: The study demonstrates that DMSO is a thermodynamic hydrate inhibitor, with a linear correlation between its mass fraction in solution and gas pressure. Compared to methanol, DMSO exhibits more effective anti-hydrate activity due to the higher non-ideality of its aqueous solutions.
