(b) Methanol is made by the reaction of CO with H, according to the reaction CO +2H, → CH,OH The gas mixture entering the reactor is contaminated by small amounts of methane. The composition of the gas mixture is follows: CO = 32.5%, H, = 67.3% and CH4 = 0.2% %3D 64341 The single pass conversion of CO in the reactor is only 18%. The exit stream from the reactor is sent to a separator in which methanol is separated and removed. The unconverted gases is arecycled and mixed with the fresh feed before being admitted to the reactor. It is desired that the methane content in the recycle stream be not more than 3.0%. This is achieved by bleeding off a portion of the recycle stream at the exit of the separator. Calculate per 100 moles of fresh feed the following :
