A simpler, non iterative solution exists.

For each kmol/s methane, you already know you need 0.56 kmol/s oxygen. You can measure the methane flow rate in the methane feed, and calculate directly the required oxygen flow using an information calculator. And put this number into the flow constraint.

3] Controller is given a set point to adjust above to say zero
4] Output from controller (another information stream) sends this information to a control element (flow constriction in feed) to meet set point
