“…Equipment complexity, energy consumption, and high capital costs do not prevent them from being mature and reliable methods. Therefore, the membrane separation method represents a promising solution for the scientific and industrial community due to low capital costs, ease of design and operation, low operating and maintenance costs, low energy consumption, and the absence of environmental damage [ 1 , 2 ].…”

“…The global market for gas separation membranes was estimated at USD 897 million in the year 2022, and is projected to reach a revised size of USD 1.1 billion by 2026 [ 2 ]. The porous and non-porous membranes are utilized to detach CO 2 from natural gas; however, in large-scale applications, all the membranes depend on a high-density polymer membrane.…”

In this work, the capture of carbon dioxide using a dense hollow fiber membrane was studied experimentally and theoretically. The factors affecting the flux and recovery of carbon dioxide were studied using a lab-scale system. Experiments were conducted using a mixture of methane and carbon dioxide to simulate natural gas. The effect of changing the CO2 concentration from 2 to 10 mol%, the feed pressure from 2.5 to 7.5 bar, and the feed temperature from 20 to 40 °C, was investigated. Depending on the solution diffusion mechanism, coupled with the Dual sorption model, a comprehensive model was implemented to predict the CO2 flux through the membrane, based on resistance in the series model. Subsequently, a 2D axisymmetric model of a multilayer HFM was proposed to simulate the axial and radial diffusion of carbon dioxide in a membrane. In the three domains of fiber, the CFD technique was used to solve the equations for the transfer of momentum and mass transfer by using the COMSOL 5.6. Modeling results were validated with 27 experiments, and there was a good agreement between the simulation results and the experimental data. The experimental results show the effect of operational factors, such as the fact that temperature was directly on both gas diffusivity and mass transfer coefficient. Meanwhile, the effect of pressure was exactly the opposite, and the concentration of CO2 had almost no effect on both the diffusivity and the mass transfer coefficient. In addition, the CO2 recovery changed from 9% at a pressure equal to 2.5 bar, temperature equal to 20 °C, and a concentration of CO2 equal to 2 mol%, to 30.3% at a pressure equal to 7.5 bar, temperature equal to 30 °C, and concentration of CO2 equal 10 mol%; these conditions are the optimal operating point. The results also manifested that the operational factors that directly affect the flux are pressure and CO2 concentration, while there was no clear effect of temperature. This modeling offers valuable data about the feasibility studies and economic evaluation of a gas separation unit operation as a helpful unit in the industry.

“…In such structures, water molecules are the hosts, and gas molecules are the guests. 1 m 3 hydrate can hold up to 160–180 m 3 of gas volume under normal conditions. , It is precisely due to the property of containing a large amount of gas, hydrates are of interest in many areas besides the storage and transport of natural gas, − such as carbon dioxide capture, , mixture gas separation, seawater desalination, and others. However, one of the main problems in the deployment of hydrate-based technologies is the sluggish kinetics of hydrate formation.…”

Water-soluble polymers have shown dual characteristics either as hydrate promoters (enhanced the rate of gas hydrate formation) or inhibitors (retarded the hydrate formation kinetics). Therefore, in this study, we evaluate the promotional/inhibition effect of the environmentally friendly biodegradable, water-soluble polymers for methane hydrate formation. An unstirred highpressure reactor was used to synthesize methane hydrates of frozen biopolymers. A comparative analysis of the hydrate formation growth for concentrations ranging from 0.1 to 4.0 wt % of the frozen crushed bipolymer was performed. Further, to probe the impact of melting rates of the frozen powder on methane hydrate growth, frozen powdered biopolymers were characterized using the nuclear magnetic relaxation (NMR) spectroscopy method at a temperature of 272.2 K. From the kinetic and NMR experiments, a direct correlation between the transition rate of water to hydrate and the melting rate of frozen powdered biopolymers was established. Furthermore, this study allows us to classify the best biopolymers to enhance the kinetics of hydrate formation. Our findings highlight the promise of engaging biopolymers for solidified natural gas technology to store and transport natural gas.
