(567c) Ideas As a Process Intensification Tool Applied to Process Networks Containing Membrane Reactors
Membrane reactors are an emerging technology in the steam-methane reforming (SMR) process; these reactors typically involve simultaneous reaction and separation3. The biggest advantage of this technology is that it allows in situ separation, which gives rise to a high-purity product. This is particularly useful in driving the forward reaction of equilibrium limited reactions, as product is continuously removed from the reactor. The use of equilibrium reactor models allows for the search of intensified designs to be carried out in the lower-dimensional space of atomic fraction ratios, rather than the space of species mole fractions.
The process network considered will feature pressure changing devices, equilibrium reactors, a heat exchange network, flash separators, ideal separators, and membrane reactors. Operating and capital cost studies are all presented to determine the process networkâs cost relative to traditional steam methane reforming.
