: Hollow fiber membranes are frequently used to remove CO 2 gas during the gas sweetening process due to their advantages such as cost-efficiency, simplicity of operation and maintenance, and compact size. Permeate flux behavior, which is governed by various factors such as membrane features and operating conditions, has a significant impact on the performance of membrane separation. The majority of existing research studies focused on enhancing the permeability and selectivity of membranes. The configuration and operation of membrane modules have received scant attention in investigation. The geometrical layout and operational parameters of a membrane module were taken into account as a multivariable optimization problem in this study. The total annual cost serves as the objective function. A construction expenditure based on the size of the membrane plant plus an operational expense related to energy usage make up the total cost. The module dimensions (fiber diameter, fiber length, and packing density) and operating conditions (inlet pressure) were taken into consideration as the design factors in the optimization problem. The membrane area and energy consumption, which are directly related to the overall cost, were calculated using a model to simulate the membrane plant. To simulate multicomponent gas transport through hollow fiber modules, a membrane model with a high prediction accuracy was adapted from a previous work and solved numerically using an orthogonal collocation method. The optimization process was carried out using a genetic algorithm. This study also investigated how different parameters affect the overall cost. The accuracy of the self-developed computation program was checked with the results obtained from ChemBrane. The relative difference in the results obtained from our program and ChemBrane is less than 1%, suggesting the applicability of our model and program. The proposed optimization process is able to find the conditions of the module that meet the requirement of CO 2 concentration of effluent while minimizing the cost. The results suggest that the use of polyamides has a lower cost than the use of cellulose acetate membranes.

. The prilling technique is frequently used to make granular urea and ammonium nitrate. The generated droplets fall and become solid due to the heat removal by the cooling air, which flows in a counter-current direction. Generally, three sequential thermal intervals for the solidification of urea droplets are considered: cooling of liquid drops, solidification at freezing temperature of the liquid phase, and cooling of complete solid particles. In this study, the solidification of the urea droplets has been considered as a two-phase Stefan problem with convective flux boundary condition rather than dividing the whole process into three sequential steps. The heat transfer problem was solved numerically using the enthalpy method. The particles were assumed to attain the terminal velocity immediately. The convective heat transfer was determined from the terminal velocity. The temperature distribution of the droplets, and the minimum height for complete solidification at different particle diameters were investigated.

: Due to their unique physical properties, microbubbles have received a lot of attention in waste treatment, aquaculture, and food processing. The demand for high-efficient and low power consumption microbubble generators has become a challenge today. Swirling flow has been widely proven to improve bubble formation. Numerous researchers have developed designs to produce swirl flow and strengthen the turbulence fluid flow. In this study, we present a swirl venturi microbubble generator with a 60 ◦ twisted baffle fin on the inlet section. The performance of the microbubble generator swirl venturi type was tested experimentally using parameters such as the distribution of bubble size, hydraulic power (L w ), and bubble-generating efficiency ( η b ). A microbubble generator was installed in the transparent test pool with 672 L of water. A high-speed video camera was employed to visualize the flow behavior. The water and gas flow rates varied between 40 and 60 lpm and 0.1 and 0.5 lpm, respectively. The data were analyzed by MATLAB R2022b with the technique image processing method. The results showed that majority bubbles 100–300 µ m were generated. An increased water flow rate (Q L ) will increase the hydraulic power by 22–27 W, while an enlargement of the gas flow rate (Q G ) would only enlarge it by 1 W. As the water flow rate increases, bubble-generating efficiency decreases. The lowest bubble-generating efficiency of 0.008% occurs at a Q L 60 lpm and Q G of 0.1 lpm. In conclusion, we can conclude that the microbubble generator swirl venturi type is an efficient device for generating microbubbles.

: Supercritical fluid extraction (SFE) is a non-conventional extraction technique that can be used in the food industry because it can recover both polar and non-polar compounds. This technique is carried out above the critical point of the extraction solvent, allowing for the control and manipulation of different properties such as diffusivity, viscosity, and density. This is possible due to the fluid’s changes in pressure and temperature that cause variations in selectivity and power. This eco-friendly extraction technique has several advantages, including high selectivity due to changes in pressure and temperature, as well as changes in the solvent’s polarity by adding co-solvents. SFE has already been used in the food industry due to the benefits of this technique and its suitability for both polar and non-polar compound extraction. The goal of this work is to compile the most recent data on SFE applications in the food industry, thereby providing insight into SFE feasibility in a large-scale process.

: Per-and poly-fluoroalkyl substances (PFASs) are recalcitrant chemicals with stable carbon– fluorine (C–F) bonds. These complex substances are difficult to degrade; therefore, they persist in the environment, causing potential health effects on humans. This study focused on the photocatalytic degradation and defluorination of perfluorooctane sulfonate (PFOS) in aqueous water using TiO 2 nanoparticles under UV–visible light. The biosynthesized TiO 2 catalysts at pH 8, 10, and 12 were characterized using XRD, HRTEM, and HRSEM. The XRD patterns of the respective TiO 2 nanoparticles at different synthesized pHs exhibited similar anatase phases, and it was observed that the crystallite sizes decreased with increasing pH. The HRSEM and HRTEM confirmed the spherical shapes of the produced nanoparticles with particle size distributions of 12.17 nm, 10.65 nm, and 8.81 nm for the synthesized TiO 2 nanoparticles at pH 8, 10, and 12, respectively. The photodegradation and defluorination of PFOS were performed at various initial solution pH values of 2, 4, 6, 8, 10, and 12 under UV irradiation for 150 min. The study showed 95.62 and 56.13% degradation and defluorination efficiency at pH 2. The degradation and defluorination efficiencies significantly decreased as the pH of the solution increased; hence, the degradation increases at lower solution pHs. Without UV–visible light, the photocatalysis achieved a lower degradation and defluorination efficiency. The photocatalysis showed that the pH of the solution and UV irradiation greatly influence the degradation and defluorination. Therefore, TiO 2 nanoparticles were effective for the degradation and defluorination of PFOS under UV–visible light, which could also have an influence on the treatment of other PFASs in wastewater.
