2. Why Membrane Separation and
Reactor?
• Separation of very fine particles.
• Cleaner operation, due to absence of large cakes
that are produced during normal filtration.
• Lower resistance due to absence of cake, hence
faster operation.
• Closed System, hence low contamination
• Membrane Reactors are continuous and does
not need regeneration unlike the other solid bed
operations.

3. Abstract - Summary
• Membrane Processes and Membrane
Reactors in various stages of Petrochemical
Industry.
• Olefin/paraffin separation
• Light solvent separation
• Solvent dewaxing
• Phenol and aromatic recovery
• Dehydrogenation,
• Steam reforming of methane
• Oxidative coupling of methane

4. Steam Reforming of Methane
• Conventional Method: 800 0C and 20 atm
• Pd Alloy Membrane with traditional SMR Catalyst

5. Oxidative Coupling of Methane
• Desired Liquid fuels :- Ethane, Ethylene

6. Oxidative Coupling of Methane
Porous Ceramic Membrane
Reactors
• High Stability for
Reactions
• Low O2 selectivity,
hence lesser yield of C2
products.
• Hollow fiber Ceramic
Membrane can be
used, as it is a special
type with higher
selectivity of Oxygen.
Dense ionic oxide membrane
reactors
• Theoretically Infinite O2
selectivity
• Still in Development
