Abstract:
This report summarizes the state of the art of membrane techniques forseparation of hydrogen from other gases, for application within IGCC-processes
fuelled with refinery residuals and biomass.
Although the number of hydrogen selective membrane applications is currently
still rather limited, research is performed to increase the range of
applications.
The properties of the flow to be separated are the starting point to
select a suitable membrane. For a preliminary choice of a membrane type,
the operating temperature ranges can be used, although the feed composition
and cost should also be taken into account. Once the membrane is selected,
a membrane module can be chosen or designed taking into account considerations
such as manufacturability, maintainability, operability, efficiency,
membrane deterioration, and costs. Modules can be combined to form stages.
By combining multiple stages and adding features, a range of membrane
systems can be designed. This versatility greatly adds to the attractiveness
of membrane systems.
