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 presence single mixed acid gases (CO 2 H 2S). A static analytic method was used for performing all measurements. Methane to maintain total pressure system equilibrium cell. The concentration phase 50-1000 ppm (mole) range. effect gas loadings on physical chemical is discussed.
