The paper presents the results of the development of a unit for calculating mass transport in a membrane gas separation apparatus in the Aspen Plus environment. The created user model has been verified by comparing the results of the calculation of separation characteristics with available experimental data for two cases. In the first case, the calculation results were compared with experimental data on the separation of the ternary H 2 O/EtOH/N 2 (13.3/5.5/81.2 mol %) vapor-gas mixture simulating the stream from the stripping column of a laboratory membrane vapor separation unit with a plate-and-frame membrane module for ethanol recovery from fermentation broth. It has been shown that the calculated concentrations of the components in the retentate and permeate streams are close to the experimental values obtained in the separation of the ternary vapor-gas mixture. In the second case, the calculation results were compared with experimental data obtained upon the separation of a binary N 2 /CH 4 gas mixture (99/1 mol %) simulating a stream with a low content of an easily penetrating impurity component using a radial membrane module. It has been found that the calculated concentration of CH 4 in the retentate is noticeably less than in the experiment, especially at high stage cuts, a difference that is associated with the increasing influence of the longitudinal mixing of components at low speeds of the mixture in the channels of the membrane module, which deteriorates the separation characteristics of the apparatus with respect to the removal of impurities and requires additional consideration of the deviation from the plug-flow mode in computational mathematical models used for this case.

Simulation of the Membrane Process of CO2 Capture from Flue Gas via Commercial Membranes While Accounting for the Presence of Water Vapor

Carbon capture and storage is one of the potential options for reducing CO2 emissions from coal-fired power plants while preserving their operation. Mathematical modeling was carried out for a one-stage membrane process of carbon dioxide capture from the flue gases of coal-fired power plants using commercial gas separation membranes. Our calculations show that highly CO2-permeable membranes provide similar characteristics with respect to the separation process (e.g., a specific area of membrane and a specific level of electrical energy consumption) despite the significant variation in CO2/N2 and H2O/CO2 selectivity. Regarding the development of processes for the recovery of CO2 from flue gas using membrane technology, ensuring high CO2 permeance of a membrane is more important than ensuring high CO2/N2 selectivity. The presence of water vapor in flue gas provides a higher driving force of CO2 transfer through the membrane due to the dilution of CO2 in the permeate. A cross-flow membrane module operation provides better recovery of CO2 in the presence of water vapor than a counter-current operation.

Membrane–based gas separation has become an important research field for sustainable energy and environmental applications. Gas separation is one of the key steps in refineries and other gas‐related industries. Over the last two decades, the research on extended porous organic and inorganic materials such as zeolites, metal–organic frameworks (MOFs), covalent–organic frameworks (COFs), and their hybrids has increased continuously. These materials have garnered significant interest due to their structural flexibility and pronounced porosity, which offer excellent potential for gas adsorption and separation processes in industrial settings. As such, this review has aimed to provide an in‐depth analysis of the recent developments in MOFs, COFs, and MOF–COF hybrid‐based membranes for gas separation, highlighting their potential for practical industrial applications. It also offers a comprehensive understanding of some of the most critical and advanced materials used in gas separation compared to common polymers. In addition, membranes' concepts, efficiency, and cost‐effectiveness are discussed in detail.
