A problem that has been puzzling me is that, in a plasma-assisted chemical reaction, e.g. methane or methanol reforming, how to determine the flow rate of outlet gas which will be then used for reactant conversion and products selectivities calculation as well as the mass balance analysis.
Because the components of gaseous products are changeable, mass flow controller or rotameter can not be used for flow rate measurement. Some authors just assume that: inlet flow rate=outlet flow rate, but this is not accurate, especially for liquid fuel reforming, such as methanol.
So, how to determine the outlet gas flow rate? Thanks very much.
1. Choose the solvent for the sought-for component of the outlet gas.
2. Find any method of the analytical chemistry to determine concentration of the solved substance.
3. Bubble the outlet gas through solvent for a some time, find the concentration, profit.
