Dataset for the dimethyl sulfoxide as a novel thermodynamic inhibitor of carbon dioxide hydrate formation.

ABSTRACT: The temperatures and pressures of the three-phase equilibrium V-L_w-H (gas - aqueous solution - gas hydrate) were measured in the CO₂ - H₂O - dimethyl sulfoxide (DMSO) system at concentrations of organic solute in the aqueous phase up to 50 mass%. Measurements of CO₂ hydrate equilibrium conditions were carried out using a constant volume autoclave by continuous heating at a rate of 0.1 K/h with simultaneous stirring of fluids by a four-blade agitator at 600 rpm. The equilibrium temperature and pressure of CO₂ hydrate were determined for the endpoint of the hydrate dissociation in each experiment. The CO₂ gas fugacity was calculated by the equation of state for carbon dioxide for the measured points. The flow regime in the aut
