2. In the methanol synthesis described above, small quantities of non-reactive gaseous impurities (N2, hydrocarbons) are presented in the feed. They do not dissolve to any appreciative extent in the liquid methanol product, so they must be removed by a purge in the recycle line. If they are not removed, the concentration of impurities and the pressure will increase, to the detriment of the desired reaction.

FUL2 9 In the methanol synthesis described above, small quantities of non-reactive gaseous impurities (N2, hydrocarbons) are presented in the feed. They do not dissolve to any appreciative extent in the liquid methanol on product, so they must be removed by a purge in the corecycle line. If they are not removed, the concentration of impurities and the pressure will increase, to the detriment of the desired reaction. The feed gas contains 66.6% H₂, ELSTOL 33.33% CO and 0.1% non-reactive impurities. The plant produces 1000 gal/h of methanol at 70°F with a 15% conversion in the reactor.
