Industrial
separations are involved in almost every chemical and petrochemical process and
represent a significant percentage of capital and operating costs in these
industries. Membrane based separations
offer the potential to reduce both these costs while delivering improved
product purity. TDA proposes the
development of a new process and material for the production of supported
inorganic membranes with pore diameters in the 10 Å to 20 Å range. The new supported membranes have adsorption
properties similar to Group VII metals but are resistant to coking and sulfur
poisoning. These new membrane materials
are expected to provide both high permeance and high separation factors for
hydrogen. In the Phase I project TDA
will prepare the supported membranes and characterize their performance for
separation of hydrogen from light hydrocarbon off-gas streams
Commercial Applications and Other
Benefits as described by the awardee:
In the Phase I project, we will demonstrate the use of a new membrane
material for the separation of hydrogen by competitive adsorption and selective
surface diffusion. Separation of
hydrogen from mixed gas streams is expected to have a significant bottom-line
effect on a number of large industrial processes (e.g. ammonia production,
refinery operations, methanol synthesis, paraffin to olefin conversion, etc.)
where hydrogen separation is inefficient and costly.
