“…Interestingly, it appears that this trend is against the boundary layer heat and mass transfer theory, and is totally different from previous results using water vapor saturated gas stream as the feed [19,23,27]. Mass and heat transfer rates should increase or be relatively stable with the rise in fluid flow rate when the boundary layer effect is significant or insignificant, respectively [32][33][34][35].…”

“…In our previous studies, saturated gas streams at relatively low temperatures (< 85°C) were studied with both monochannel and multichannel ceramic tubes [19,27]. In the current work, we employ a new method to generate simulated flue gas (relatively humidity: 11-14 vol.% at 100 °C) and explores the feasibility of employing nanoporous tubular ceramic membranes for simultaneous water and heat recovery from simulated flue gas.…”

Simultaneous heat and water recovery from flue gas by membrane condensation: Experimental investigation, Applied Thermal Engineering (2016), doi: http://dx.doi.org/10.1016/j.applthermaleng. 2016.11.101 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. 1Simultaneous heat and water recovery from flue gas by membrane A tubular ceramic membrane is investigated as the condenser for simultaneous heat and water 2 recovery from flue gas. The effects of the operational parameters, such as fluid (gas and water) 3 flow rates, temperatures of flue gas and coolant water, and flue gas humidity on the process 4 performance in terms of mass and heat transfer across the membrane are studied. Particularly, 5 the overall heat transfer coefficient is also evaluated. As the gas flow rate increases, water and 6 heat transfer efficiencies and recoveries decline due to the reduced residence time. Increasing 7 the water flow rate or lowing the coolant temperature can effectively improve mass and heat 8 transfer efficiencies and recoveries. Increasing the temperature of the inlet gas can enhance 9 water and heat fluxes and recoveries, but does not improve the overall heat transfer efficiency. 10The rise in flue gas humidity can dramatically improve water and heat transfer rates and the 11 overall heat transfer coefficient, but has little effect on water and heat recoveries. These 12 results offer a general guideline in optimising the operational parameters in low-grade heat 13 recovery with membrane heat exchangers, and it may greatly advance the development of 14 membrane condensation technology for practical low-grade heat recovery.

“…Instead of carrying out a study using conventional flue gas, Gao et al [24] carried out a study to research the effect of SO 2 on ceramic membrane extracting water. A multi-channel ceramic membrane in place of a single membrane was used for experimental studies by Yue et al [25]. It was revealed that the multi-channel membrane tube had a lower mass transfer rate and heat recovery rate by comparing the two types of tubes.…”

In this work, a ceramic membrane tube with a pore size of 1 µm was used to conduct experimental research on moisture and waste heat recovery from flue gas. The length, inner/outer diameter, and porosity were 800 mm, 8/12 mm, and 27.2%, respectively. In the experiments, the flue gas, which was artificially prepared, flowed on the shell side of membrane module. The water coolant passed through the membrane counter-currently with the gas. The effects of flue gas flow rate, flue gas temperature, water coolant flux, and water coolant temperature on the membrane recovery performance were analyzed. The results indicated that, upon increasing the flue gas flow rate and its temperature, both the amount of recycled water and the recovered heat increased. The amount of recycled water, recycled water rate, recovered heat, and heat recovery rate all decreased as the water coolant temperature increased. When the water coolant temperature exceeded 30 • C, the amount of recycled water dropped sharply. The maximum amounts of recycled water, recovered heat, and total heat transfer coefficient were 2.93 kg/(m 2 ·h), 3.63 kW/m 2 , and 224.3 W/(m 2 ·K), respectively.Materials 2020, 13, 804 2 of 18 are required. At present, the production of adsorbent in the adsorption technology requires a large amount of energy; thus, adsorption technology is less economical. Additionally, the treatment of precipitate formed by the contact between the flue gas and the absorbent is technically difficult [9,10]. Usually, the membrane materials used in flue gas moisture recovery are fiber membranes and ceramic membranes. Although the membranes are relatively expensive to manufacture, they take advantages of high efficiency, reliability, and heat and chemical resistance [11,12]. Therefore, membrane separation technology is more promising in the flue gas moisture recovery field.Regarding fiber membranes, Sijbesma et al.[13] comparatively studied two membrane bundles composed of polyether block amide (PEBAX ® 1074) and sulfonated polyether ether ketone (SPEEK) membrane materials for moisture recovery from power plant exhaust. The results revealed that the performance of SPEEK fiber membrane with a sulfonation degree of 60% was better. Under the real flue gas condition, the vapor removal rate of the membrane was 0.2 to 0.46 L/(m 2 ·h). Gao et al. [14] performed an experimental study on a polyether sulfone-sulfonated polyether ether ketone (PES-SPEEK) hollow-fiber membrane applied to recycle water from exhaust gas. The influences on water and waste heat recovery, such as sulfonation degree, coating, filling rate, and length of membrane, were analyzed. The fiber membranes mentioned above are all hydrophilic. For hydrophobic membranes, the Macedonio team constructed a membrane condenser using polyvinylidene fluoride hollow-fiber membranes and carried out simulation calculations [11]. They showed that the water recovery rate could reached 20% when the exhaust temperature drop was less than 5 • C. Brunetti et al. [15] experimentally examined the effect of ∆T (t...

Summary Using nanoporous ceramic composite membranes to remove sulphur dioxide and to recover water vapor in flue gas is a new method, and this paper studied the effects of sulphur dioxide on the water recovery process. In this study, the outer‐side coating of hollow nanoporous ceramic composite membrane is selected as the study object. In the membrane module for desulphurization, one end of membrane is closed to create the high‐pressure environment inside membrane to ensure that the cooling water in the membrane penetrates the outer surface of the membrane to form a stable water film which can absorb sulphur dioxide from flue gas. In the membrane module for recovering water, using a vacuum pump to create micro‐negative pressure environment inside membrane, and then water vapor and condensate can penetrate through the membrane under pressure difference. Based on the ceramic composite membrane module, an integrated experimental platform for desulphurization and water recovery is constructed, and the mathematical model for predicting water recovery performance is established. According to the experimental and theoretical results, the mathematical model can predict the water recovery performance of the ceramic composite membrane.
