Mass transfer and pressure loss in spiral wound modules
Abstract
The performance of a spiral wound element, i.e. permeate flow and quality can be calculated by numerical integration of balance equations. The same is valid for the calculation of optimal element geometry. For this a computer program is required which needs reliable input data regarding geometrical parameters and transport characteristics. This paper presents some experimental data for pressure drop and mass-transfer characteristics in spiral wound elements and in spacer-filled flow channels. The experimental results and the computer program were used to calculate the performance of a spiral wound element and its possible design variations.

A computational fluid dynamics study on TPMS-based spacers in direct contact membrane distillation modules
2024, DesalinationFeed spacers are incorporated in membrane modules to enhance fluid mixing, thereby enhancing membrane flux. Previous experimental work showed that triply periodic minimal surfaces (TPMS)-based spacers induce significant improvements in membrane distillation (MD) performance, which was attributed to the suppression of membrane boundary layer, reducing heat and mass transfer resistance. To corroborate those findings, in this study, we assess the performance of TPMS spacers in direct contact MD (DCMD) modules using computational fluid dynamics (CFD). Results showed that the Fischer-Koch S TPMS spacer topology achieved twice the flux of the empty channel case and exhibited a 13 % increment in flux compared to the net-type spacer, but this improvement was accompanied by a higher pressure drop in the feed channel. Therefore, a normalized power ratio (NPR) was used to evaluate the overall performance of spacers. For Reynold number (Re) ranging between 200 and 1200, Fischer-Koch S spacer had a 12 % improvement in NPR compared to the net-type spacer and resulted in higher shear stress near the membrane surface, indicating a promising mean for mitigating fouling in membrane distillation. This research highlights the importance of utilizing novel spacers in membrane distillation and showcases the power of CFD tools in optimizing the process.
Iterative real-time optimization of a membrane pilot plant
2024, Control Engineering PracticeIn this paper, we describe the implementation and experimental validation of iterative real-time optimization (RTO) at a continuously operated membrane separation pilot plant. The objective is to achieve an economically optimal operation using the transmembrane pressure and the feed flow rate as adjustable operational parameters (set-points for the lower-level plant controllers). In spite of the popularity of RTO based on rigorous nonlinear plant models in the research literature, its practical use so far remains limited to large scale plants in the petrochemical industries. The main issue behind the limited application of RTO schemes is the necessary effort to derive and maintain sufficiently accurate models of the plants. In case of a significant plant-model mismatch, the results are not reliable, the optimal performance is not reached and even systematic violations of constraints may occur. The applicability of RTO could be extended significantly if simple process models sufficed for its successful application. Then an adaptation of the model or of the optimization problem to the real behavior of the plant is necessary to achieve an optimal operation. For this example, we tackle this issue by applying an iterative scheme called modifier-adaptation with quadratic approximation in combination with model adaptation to ensure the convergence of the plant to the true process optimum despite the fact that the model has deficiencies. The experimental results show that, in spite of a considerable plant-model mismatch, the presented RTO scheme is capable of boosting the process economics.
A commercial-size prototype of countercurrent spiral-wound membrane module for flue gas CO<inf>2</inf> capture
2024, Journal of Membrane ScienceIn spite of significant advancements in the synthesis of lab-scale polymeric membranes for CO2 separation, only a limited number of studies have transitioned to pilot-scale studies. Fabricating membrane modules is a critical step in realizing the commercialization of gas separation membranes for post-combustion carbon capture, yet specific details regarding this process are rarely demonstrated. In this study, a commercial-size ⌀8ʺ prototype of countercurrent sweep spiral-wound (SW) membrane module with an amine-containing facilitated transport membrane was successfully fabricated. The module comprised 41 membrane leaves, each with a width of 20ʺ and a length of 36ʺ, resulting in a total effective membrane area of 35 m2. To ensure an even distribution of sweep flow on the permeate side to minimize pressure drop, a new epoxy glue dot line pattern was strategically designed to create a countercurrent flow configuration. The SW membrane module exhibited consistent transport performance aligning with the results of the flat-sheet membrane. The successful fabrication of the commercial-size prototype highlights the exceptional potential and effectiveness of the developed full-scale membrane module in effectively tackling the challenges associated with CO2 capture from flue gas.
Angular vibrations for fouling control during ultrafiltration of microalgae in a spiral wound module
2024, Journal of Membrane SciencePrevious studies have shown that vibration- or rotation-based techniques can effectively mitigate the fouling and concentration polarization during membrane filtration. However, it is difficult to incorporate these active enhancement techniques with spiral wound modules (SWMs), which are widely employed in drinking water and wastewater treatment. In this work a prototype membrane system was developed to accommodate angular vibrations with a modified SWM. With this prototype system, a series of filtration experiments were designed and implemented to investigate the effect of angular vibrations on the ultrafiltration algal fouling process in an SWM. The experimental results indicate that the algal fouling in an SWM can be effectively controlled (up to ∼28.5 % at 15 Hz) by applying angular vibrations in conjunction with appropriate operating conditions; the underlying mechanisms are discussed using a mathematical model that accounts for the relative motion between the fluid and membrane when they are subject to external accelerations, related to the vibration frequency, filtration period and position along coiled membrane leaves. A quantitative analysis is also presented to demonstrate the potential of using angular oscillations to control the algal fouling in an SWM with a lower energy consumption compared to the conventional method of increasing the cross-flow rate.
Three-dimensional concentration-polarization modeling of trace-ions in reverse osmosis
2024, Journal of Membrane ScienceConcentration polarization (CP) is mostly evaluated through one-dimensional (1D) film models considering convective and diffusive transport of solutes. However, in multicomponent ionic solutions, electromigration and chemical speciation may also play a role in the solute transport within the CP layer, thus affecting the process performance. We developed a three-dimensional (3D) numerical model for evaluating the CP in spacer-filled feed reverse osmosis (RO) channels by coupling hydrodynamics with the transport of solutes by convection, diffusion and electromigration, and chemical speciation by several ion-pairing equilibria. A realistic spacer geometry was obtained by CT-scans of commercial RO spacers. The model revealed highly non-uniform distributions of CP, mass transfer coefficients and precipitation potential on the membrane. While electromigration tends to equalize the fluxes of dominant ions, increases locally the CP of anions and decreases that of cations, it was found not to significantly affect the boundary layer thickness. However, the chemical speciation strongly affected the CP of trace ions binding with dominant ions. Finally, the 3D results were compared with those obtained from simpler 1D models. While 1D approaches help explaining qualitatively the effects of electromigration and speciation, and serve as a reasonable first approximation, they do not capture the non-uniform distribution of concentrations, mass transfer rates or saturation indices. The model will be used to study the full length of an RO membrane module and thus provide better indicators of the overall performance of the separation process.
Performance evaluation of regeneration of high-concentration liquid desiccant using direct contact membrane distillation
2024, Separation and Purification TechnologyMembrane-based absorptive dehumidification is an attractive technique for humidity control that reduces energy consumption. The process involves a dehumidifier that absorbs moisture with a liquid desiccant, and a regenerator that concentrates the desiccant solution to complete the process cycle. In this study, a regeneration module employing a membrane distillation (MD) mechanism was developed, and its performance was evaluated theoretically and experimentally. Detailed theoretical investigations demonstrated the impact of the spacer on the convective thermal and material transport at the membrane surface at a high desiccant concentration. The module employs a hydrophobic and microporous composite membrane consisting of a polypropylene support layer and an active layer composed of polytetrafluoroethylene. For all the experiments, the desiccant solution used was an aqueous solution containing 25 wt% of lithium chloride. The transmembrane flux of the regeneration module was evaluated at different feed and permeate flow rates from 0.6 to 1.4 L/min at solution temperatures of 45 to 80 ℃ and a permeate temperature of 25 ℃. The permeate flux of the regeneration module with the spacer-filled channel increased by more than 50 % compared with that of the empty channel. The regeneration module using spacers achieved a permeate flux ranging from 1.9 to 4.3 kg/m2h during desiccant regeneration at a solution temperature of 50 ℃.
