摘要：

Binary and multicomponent vapor-liquid equilibria of synthesis gas components (H2, CO, CH4, and CO2), methanol and water with tetraethylene glycol dimethyl ether (tetraglyme) were studied experimentally at temperatures (473-513 K) and pressures (5.3-10.4 MPa) typical of the conventional vapor phase methanol synthesis. Both vapor and liquid phases were sampled directly and analyzed by gas chromatography. Solubilities were expressed in terms of equilibrium K values. Optimal binary interaction coefficients for all components with tetraglyme were obtained for the Soave-Redlich-Kwong equation of state (SRKEOS [I] by minimizing the error in bubble point pressure prediction. K values predicted by the SRKEOS were in good agreement with those obtained experimentally. © 1991, Taylor & Francis Group, LLC. All rights reserved.
