Abstract ：
Diffusion dialysis (DD) for acid recovery is significantly restricted by the poor acid dialysis coefficient (UH+$$ {U}_{{\mathrm{H}}<^>{+}} $$) of anion exchange membranes (AEMs). To overcome such problem, porous AEMs with extremely high free space volume have been fabricated herein based on porous membrane substrate, drawing inspiration from the dissolution-diffusion concept. Specifically, chloromethylated polyethersulfone (CMPES) has been used as the starting material to create the porous substrate via non-solvent phase inversion, then in-situ crosslinked and quaternized using ethylenediamine (EDA) and N-methylimidazole (NMI), respectively. In this study, the degrees of modification of EDA and NMI are controlled to adjust the microstructure and DD performance of the produced porous AEMs. The ideal AEM's UH+$$ {U}_{{\mathrm{H}}<^>{+}} $$ and acid/salt separation factor (S) are 4.3 and 2.6 times greater, respectively, than those of the commercial DF-120 membrane at the same condition. Additionally, it shows strong organic solvent resistance and thermal stability, and therefore demonstrate the potential for widespread use.

Abstract ：
Economically separating 1-propanol (NPA) from water is an emergent issue for producing pharmaceutical intermediates such as n-propyl acetate, n-propylamine and so on. In this work, fourionic liquids (ILs) 1-ethyl-3-methylimidazolium thiocyanate ([EMIM][SCN]), 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]), 1,3-dimethylimidazolium methylsulfate ([MMIM][MS]), 1,3-dimethylimidazolium dimethylphosphate ([MMIM][DMP]) were introduced as potential entrainers for separating NPA-water azeotropic mixture. The results show that [MMIM][MS] is the most suitable entrainer compared with other ILs from the analysis of vapor-liquid equilibrium and relative volatilities. The extractive distillation process with the entrainer regeneration system of flash tank and stripper was employed and optimized by the two-step optimization method. The results show that total annual cost and energy consumption per product flow rate were reduced by 39.79% and 60.47% compared with literature. In addition, the effi-ciency indicator of extractive section, efficiency indicator of per tray in extractive section, carbon dioxide emissions were also selected as the evaluation index for selection of operating parameters and calculated for different cases. The CO2 emissions of the optimal design can be reduced by 60.98% from environmen-tal aspect.(c) 2022 The Chemical Industry and Engineering Society of China, and Chemical Industry Press Co., Ltd.

Abstract ：
A systematic procedure is proposed for the design of a pressure-swing distillation (PSD) process for a ternary mixture. This procedure involves thermodynamic insight, global optimization, and heat integration. The aim of thermodynamic insight is to analyze the process feasibility and find all of the possible separation sequences via residue curve maps and the distillation boundaries. The global optimization for a total of 16 variables in three columns is conducted by multiobjective genetic algorithm (MOGA) with economy and environmental impact as objectives. In heat integration, a four-step heat integration MOGA method was first proposed to optimize the heat-integrated PSD process and the optimally integrated heat duty was achieved. The separation of a methanol/tetrahydrofuran/water ternary mixture is employed to elucidate the effectiveness of the proposed procedure. An energy-saving heat-integrated PSD process is obtained, and the total annual cost and CO2 emissions are reduced by 22.5 and 30.4% compared with the conventional PSD process.

Abstract ：
Diffusion dialysis employing anion exchange membranes (AEMs) as an energy-efficient and environmentallyfriendly technology is highly desirable for acid recovery from acidic wastewater. Herein, porous AEMs with high acid permeability were tailored via a simple one-step route, in which porous chloromethyl polyethersulfone (CMPES) membrane substrate was modified by 1,4-dimethylpiperazine (DMP) to achieve simultaneous crosslinking and quaternization. The prepared piperazine-functionalized AEMs were characterized by morphology, ion exchange capacity, water uptake, water contact angle, stabilities and diffusion dialysis performance. Specifically, the optimal AEM (i.e., DPES-3h) applied in acid recovery from the simulated HCl (1.0 mol L- 1)/FeCl2 (0.2 mol L-1) mixed solution at 25 degrees C possessed a proton dialysis coefficient (UH+) of 43.2 x 10-3 m h-1 and an acid/salt separation factor (S) of 29.6, remarkably outperforming the previously reported state-of-the-art AEMs. Furthermore, the DPES-3h AEM showed excellent thermal stability and acid resistance, suggesting considerable durability for long-term application. These results indicated that our piperazine-functionalized porous AEMs appear to be promising for acid recovery from the acidic waste streams via diffusion dialysis.

Abstract ：
Predicting the permeate flux is critical for evaluating and optimizing the performance of the forward osmosis (FO) process. However, the solution diffusion models have poor applicability in accessing the FO process. Recently, the data-driven eXtreme Gradient Boosting (XGBoost) algorithm has been proven to be effective in processing structure data in engineering problems and has not been utilized to assess the FO process. Herein, a combination of the XGBoost model with a genetic algorithm (GA) was first proposed to predict the permeate flux, highlighting its superiority in the FO process through comparison of the support vector regression (SVR) model, the artificial neural network (ANN), and the multiple linear regression (MLR). Moreover, the performance of these models was optimized by tuning hyperparameters with a genetic algorithm (GA) and compared via Taylor Diagram. Among these machine learning (ML) models, the GA-based XGBoost model is superior to the other three models in terms of mean square error (MSE, 2.7326) and coefficient of determination (R2, 0.9721) on the test data, and its prediction power was compared to that of the solution diffusion (SD) model in the literature. Finally, further insight into the feature importance that affects the permeate flux in the FO process was examined by utilizing the SHapley Additive exPlanations (SHAP) to estimate the contribution value of various variables. The results demonstrated that the XGBoost model could predict the permeate flux in the FO system with high accuracy and good generalization ability for the given data set and even on the unseen data. Furthermore, the findings of the SHAP method show that the osmotic pressure difference, the osmotic pressure difference of draw solution and FS solution, the crossflow velocity of the feed solution and draw solution, and the water permeability coefficient have a significant impact on water flux.

Abstract ：
An improved model for calculating physical properties and phase behavior of confined fluids (oil and gas resources in shale reservoirs) by considering adsorption film theory was developed based on the square-well chain-like fluid with variable well-width range (SWCF-VR) equation of state. The accuracy of the improved model is greatly increased via comparing the experimental data of argon in cylindrical pores at 87.3 K. The physical properties of pure component hydrocarbons, mixture hydrocarbons, and real Bakken oils in nanopores were predicted and analyzed. The results show that the properties of confined fluids are very different from those of bulk-phase fluids, where confinement decreases the gas-liquid phase equilibrium constant (K-value), bubble point pressure, and interfacial tension of the fluid. The presence of the adsorption film further decreases the K-value and bubble point and increases the capillary pressure, and these properties change more significantly in pore radius with only a few nanometers. The results demonstrate the importance of improving the accuracy in calculating the properties and phase behaviors of confined fluids and also draw the necessity of considering the adsorption film theory.

Abstract ：
In the sustainability concept framework, wastewater highly loaded with acid is considered as a valuable resource, rather than a waste. Diffusion dialysis employing anion exchange membranes is a feasible solution to extracting acid from this waste stream. However, conventional anion exchange membranes have dense spatial structures with no observable pores even at nanoscale, which limits the transfer of protons. Porous anion exchange membranes provide a practical avenue to enhance the proton transfer due to their unique spatial structure. In this study, novel porous anion exchange membranes were designed by one-step crosslinking and quaternization of porous brominated poly (phenylene oxide) membrane substrate by 1, 4-diazabicyclo [2.2.2] octane. The resultant porous anion exchange membranes showed a high performance in acid recovery by diffusion dialysis, due to their uniquely tailored microstructures including an extremely thin selective layer and high free space volume. Specifically, the optimal anion exchange membrane possessed an acid dialysis coefficient of 0.066 +/- 0.003 m h(-1) and an acid/salt separation factor of 96.9 +/- 2.5 in the HCl/FeCl2 mixture solution, outperforming the commercial anion exchange membrane (i.e., DF-120, acid dialysis coefficient of 0.0085 m h(-1) and acid/salt separation factor of 18.5). This study demonstrates the great potential in constructing advanced anion exchange membranes at large scale for efficient acid recovery from highly acidic wastewater to support environment sustainability.
