Methanol is used as a raw material in the manufacture of formaldehyde, acetic acid, methyl tertiary-butyl ether (MTBE), and several other important chemicals. It also has many other uses, including as a solvent, a disinfectant, and a clean-burning fuel. One of the ways it can be synthesized is by reacting carbon dioxide and hydrogen gas. The by-product of the reaction is water. The fresh feed to a methanol synthesis process contains hydrogen gas, carbon dioxide, and 0.4 mole % inerts. The reactor effluent passes to a condenser that removes essentially all of the methanol and water formed and none of the reactants or inerts. The latter substances are recycled to the reactor. To avoid buildup of the inerts in the system, a purge stream is withdrawn from the recycle. The feed to the reactor contains 28.0 mole % carbon dioxide, 70.0 mole % hydrogen, and 2.00 mole % inerts. The single-pass conversion of hydrogen is 57.0 %. Generate a process data sheet (tabular) showing molar flow rates and molar compositions of the following streams for every 500 kmol/hr of methanol produced.
