Increasingly,
U.S. refineries are short of hydrogen. Untapped
sources include off-gas and fuel gas streams generated on site. Membranes have been used for this
application, but membrane failure caused by plasticization and condensation of
heavy hydrocarbons has led to shutdown of a number of plants. In this project a new class of membrane
material that is completely inert to hydrocarbon liquids will be developed. These membranes do not fail after exposure to
vapors or condensed liquids. This will
allow hydrogen-permeable membranes to be widely used in refinery applications
to recover hydrogen. In Phase I the
reliability of the membrane will be demonstrated in bench-scale module tests
with gas mixtures known to cause failure of current membranes. A technical and economic analysis of
refinery and petrochemical plant hydrogen recovery processes using these
membranes will be performed.
Commercial Applications and Other
Benefits as described by the awardee: Hydrogen-permeable membranes have not been
widely used in refinery applications because of poor reliability. Development of hydrocarbon-resistant
membranes will allow economical recovery of hydrogen from refinery waste gas
streams.
