In this communication, experimental data for dissociation conditions of methane hydrates in the presence of 0.05 and 0.1 mass fractions NaBr, KBr, K2CO3, and MgCl2 aqueous solutions and in the presence of 0.05 and 0.15 mass fractions CaBr2 aqueous solutions are reported. The experimental data were generated using an isochoric pressure-search method. The new experimental dissociation data for methane hydrates in the presence of 0.1 mass fraction MgCl2 aqueous solution are compared with some selected experimental data from the literature and the agreements are generally found acceptable. Some of new data are finally compared with the predictions of a correlation, which is generally used in the absence of experimental data, and acceptable agreements between the experimental and predicted data are observed.
