Vapor–Liquid–Liquid Equilibrium Measurements and Modeling of the Methanethiol + Methane + Water Ternary System at 304, 334, and 364 K

“…Then CH 4 was added to reach the desired pressure. The required temperature was obtained by putting the cell into a thermoregulated oil bath.…”

“…The gas chromatograph generated peaks of the individual components [CH 4 (FID), CH 3 SH (FID), and H 2 O (TCD)] at specific retention times, which were recorded using one RS-232 interface. The areas under such peaks correspond to the number of moles of the individual components, which came from the corresponding calibration.…”

“…8,9 The CPA EOS for thiols (mercaptan-containing systems) was described in our previous publications. 3,4 The 4C association scheme was used for H 2 O according to the terminology from Huang and Radosz. 10 Furthermore, CH 3 SH was considered to be a non-self-associating fluid but capable of cross associating with H 2 O (solvation).…”

Experimental Measurements and Modeling of Vapor-Liquid Equilibrium of Isobutane and Ethyl Mercaptan Binary System

“…It is difficult to obtain experimental reliable thermodynamic data such as VLE data for a system containing sulfur compounds like hydrogen sulfide and mercaptan because of their acute toxicity and high volatility. The Centre of Thermodynamics of Processes (CTP) of Mines Paris, during the last years, has studied and measured VLE data of numerous binary and ternary systems involving hydrocarbons and mercaptans [6][7][8][9].…”

Vapour-liquid equilibria of n-butane and ethyl mercaptan: Experiments and modelling

“…The main properties of interest are vapour-liquid equilibria in the range of pressure and temperature of the operating conditions in the train of fractionation. In the last 6 years, our research group has published VLE data of binary and ternary systems involving mercaptans (without water) in several articles: Awan et al [3] (Phase Equilibria of Three Binary Mixtures: Methanethiol + Methane, Methanethiol + Nitrogen, and Methanethiol + Carbon Dioxide), Awan et al [4] (1-Propanethiol+ 1-Butanethiol+ CH 4 ), Afzal et al [5] (Ethane + Ethyl mercaptan). Mercaptans have similar molecular structure to alcohols with the oxygen (O) atom replaced by a sulfur (S) atom.…”
