Effect of acid gases on the solubility of n-propylmercaptan in 50wt% methyl-diethanolamine aqueous solution

摘要

In this communication,we have measured the solubility and partition coefficient of n-propylmercaptan in 50 wt% MDEA aqueous solution at 366 K in the presence of single and mixed acid gases(CO2 and H2S).A static analytic method was used for performing all the measurements.Methane was used to maintain the total pressure of the system in equilibrium cell.The concentration of n-propylmercaptan in aqueous phase was in the 50-1000 ppm(mole)range.The effect of acid gas loadings on the physical and chemical solubility of n-propylmercaptan is discussed.
