Question

Methanol can be produced by the gas phase catalytic reaction between carbon monoxide and hydrogen as follows: CO + 2Hâ‚‚ â†’ CHâ‚ƒOH. The feed to the process consists of a stoichiometric mixture of hydrogen and carbon monoxide, but it also contains 4% by volume of the inert gas, nitrogen. This stream is mixed with a recycle stream before being fed to the catalytic reactor. The product stream from the reactor is fed to a condenser where all of the methanol can be removed as a liquid, and the unreacted gases and the inert nitrogen are recycled to mix with the feed stream. However, as the inert gas will continue to be added to the system. With the aid of the following partially annotated PFD, answer the following. Fie FE Xg Y Z = 0.17 F X Y.. VF Xo X* Yo Y.
