methanol production from syngas mass balance

For The valuable outputs of this system are 3.34 ton/h of H2, 34.56 ton/h of O2, 5.24 ton/h of methanol and 86.74 MWe of excess electricity. Methanol has been called wood alcohol (or wood spirit) because it was obtained, commercially from the destructive distillation of wood for over a century. Catal. The optimization goals for the R-100 were to minimize carbon dioxide production (as it presented significant downstream separation issues and kinetic data was not available for modeling its conversion to methanol) and to maximize the production of syngas through the varying of temperature, pressure, and the steam-to-methane ratio. Catalyst systems used for methanol synthesis are typically mixtures of copper, zinc oxide, alumina and magnesia. The conventional commercial gas-phase process carries out the conversion in fixed-bed reactors at high pressure. Usman, M.; Wan Daud, W.M.A. 3.
