Investigation of hydrate dissociation conditions of CO2 gas in the presence of mixed promoters (TBAC + Cyclopentane)

In this communication, experimental data of hydrate dissociation conditions for CO2 + tetra nbutylammoniumchloride (TBAC) + cyclopentane (CP) + water) system is reported in the temperature rangeof (286 to 292) K, the pressure range of (0.97 to 3.51) MPa, and at various concentrations of TBAC (0.05,0.10, 0.15 and 0.20 mass fractions). The experiments were carried out using an isochoric pressure -searchmethod to obtain the experimental data and the method validity was checked by re-generating CO2 + TBAChydrate data reported in literature. The experimental results show that the presence of mixed promotersmoderates the hydrate dissociation conditions for TBAC + water + CO2 system remarkably (in theconcentration ranges studied in this work).
