General conclusions propane dehydrogenation

Probably the only possibility is the combination of a high driving force (sweep gas or low permeate pressure) and a very high selective membrane. The use of ceramic membranes in an isothermal reactor concept shows better prospects. This process, in combination with high selective membranes and the necessary membrane boundary conditions are being studied, and the results will be reported in future. 

Propane and propylene prices are the main actors in the introduction of a dehydrogenation process in general, thus also for processes based upon membrane reactors. At a price difference (propylene-propane) of 300 /tonne or less membrane based dehydrogenation processes will hardly be economic feasible.
