Membrane condensers as emerging technology for water recovery from waste gaseous streams
Adele Brunetti
The University of Calabria, Italy
The shortage of potable water has become an environmental issue more and more pressing owing to the continuous growth
in water demand not balanced by an adequate recharge. If we think the water use in power generation for boilers, cooling
and cleaning purposes account for around 22% of global water consumption. Separation and recovery of water contained in
the waste gaseous streams can be considered as a new water source, also simply pursuing the possibility that industry can close
the own water cycle by capturing evaporated water, minimizing the make-up from external sources. In this work, an emerging
technology, so-called membrane condenser for the selective removal of water from the evaporated industrial waste will be
introduced. In this system, the feed (super-saturated industrial gas) is brought into contact with hydrophobic microporous
membranes in membrane contactor configuration. The water condenses onto the membrane surface and the hydrophobic
nature of the latter prevents the penetration of the liquid into the pores, letting the dehydrated gases pass through the membrane
and retaining the liquid water at the retentive side. An experimental and simulation study is developed for predicting the
membrane-based process performance. Feed flow rate, interfacial membrane area, temperature difference between the fed flue
gas and the membrane module result the driving parameters controlling the process. The analysis of the potentialities of this
new technology is supported by the introduction of process intensification metrics which provide an alternative and innovative
point of view regarding the unit performance, highlighting important aspects characterizing the technology and not identified
by the conventional analysis. In the end, this presentation aims to give a point of view on the approach to be used for a proper
evaluation of emerging membrane technologies performance and comparison with conventional units.
