Membrane Reactor - Oxy Membrane

A membrane reactor is really just a plug-flow reactor that contains an additional cylinder of some porous material within it, kind of like the tube within the shell of a shell-and-tube heat exchanger. It has excellent and stable permeate quality and long lifespan for 5-8 years. It has large installed filling area but with small footsprint.
