Nowadays, butanol is considered as biofuel. In this work, separation of butanol from aqueous solution was carried out by vacuum membrane distillation with polytetrafluoroethylene membrane, using mechanical vapor compression on the downstream. Higher flow rates could promote membrane separation with higher total flux and higher separation factor, thus influencing butanol separation. Membrane fouling was observed which exerted a substantial effect on the membrane separation performance with a real fermentation broth. Compared to the traditional distillation process, this procedure is more cost-effective due to~50 % reduced energy consumption.

“…The water vapour transport and condensed to the shell side due to vapour pressure differenece. Liquid water is then recovered as the permeate and the energy is recovered as latent heat of the condensing vapor in the shell side [ 28 ]. The mechanism of water and heat recovery is similar to the one in membrane distillation (MD) [ 29 , 30 , 31 ].…”

Flue gas contains high amount of low-grade heat and water vapor that are attractive for recovery. This study assesses performance of a hybrid of water scrubber and membrane distillation (MD) to recover both heat and water from a simulated flue gas. The former help to condense the water vapor to form a hot liquid flow which later used as the feed for the MD unit. The system simultaneously recovers water and heat through the MD permeate. Results show that the system performance is dictated by the MD performance since most heat and water can be recovered by the scrubber unit. The scrubber achieved nearly complete water and heat recovery because the flue gas flows were supersaturated with steam condensed in the water scrubber unit. The recovered water and heat in the scrubber contains in the hot liquid used as the feed for the MD unit. The MD performance is affected by both the temperature and the flow rate of the flue gas. The MD fluxes increases at higher flue gas temperatures and higher flow rates because of higher enthalpy of the flue gas inputs. The maximum obtained water and heat fluxes of 12 kg m−2 h−1 and 2505 kJm−2 h−1 respectively, obtained at flue gas temperature of 99 °C and at flow rate of 5.56 L min−1. The MD flux was also found stable over the testing period at this optimum condition. Further study on assessing a more realistic flue gas composition is required to capture complexity of the process, particularly to address the impacts of particulates and acid gases.

Functional ultrafiltration membranes can be used for water decontamination. Here, we investigate the use of plasma polymerization to modify polymeric membranes with poly(allylamine) in order to filtrate aqueous solutions contaminated with Ni(II) ions. A preliminary study is performed to control growth kinetics of polymer thin films with respect to the energy provided to the precursor during deposition. Filtration experiments then enable to quantify the efficiency of the different functional coatings as for their retention of Ni(II) ions and to identify the optimal characteristics of the polymer thin films. Retention rate as high as 96% can be achieved by this single‐step functionalization process, which is very competitive compared to conventional multi‐step wet chemical functionalization techniques.
