Abstract
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.
