Methanol (CH3OH) is produced via partial oxidization of methane (CH4). The fresh feed contains methane and oxygen that have been mixed in stoichiometric proportions. It enters a reactor. The single pass conversion of methane is 10%. The stream leaving the reactor is passed into a separation process where the entire methanol, but none of the other materials, is removed and leaves the bottom of the column. All of the remaining materials leaving at the top are recycled to be mixed with the fresh feed. The stoichiometric proportion feeding of reactants also applies to the feed entering the reactor. 1000mol/h of methanol is produced. CH4+1/2O2CH3OH a. Draw and label a process flow chart b. Calculate the NDF for each control volume. Clearly state the number of unknowns and the number of equations c. Determine the feed rate of the stream entering the reactor
