“…According to Hoff, MEA vapor pressure is far less than that of H 2 O at the typical temperatures of CO 2 absorption processes; thus, its mass transfer is neglected. Other species generated from the CO 2 reaction with the MEA solvent are assumed nonvolatile, as it is consistent with other studies. ,, The ELECNRTL activity coefficient model and the Redlich–Kwong (RK) equation of states are used to estimate the thermodynamic properties of liquid and gas phases, respectively. , A 1D modeling approach is employed, as Zaidiza et al showed that the results of one-dimensional modeling were identical to that of a two-dimensional approach. As a result, component concentrations and temperatures of the gas and liquid phases are independent of radial coordinates. Convective flow is dominant over diffusion in the axial direction of flow …”

“…The number of stages is an input to the model and should be selected appropriately in order for the mathematical model to converge in a reasonable computational time. 39,57 The summation equation is also necessary for the gas phase to ensure that the sum of the mole fractions in stage j is equal to 1:…”

A rate-based membrane gas-solvent contactor model was programmed in Aspen Custom Modeler (ACM) and interfaced with the Aspen Plus software suite to enable flowsheet simulations of carbon capture processes. After validation with different sets of laboratory and pilot plant data, the model's rigorous approach was examined against the commercial RadFrac model of Aspen Plus used for conventional absorption−stripping column simulations. Under identical processing conditions, both models predicted similar results for the temperature, flow rate, and composition of the streams leaving the absorption and stripping units. Differences between the two models were most pronounced for liquid and gas temperature profiles, which were attributed to the different energy balance methods used in the two models, but the difference was not large enough (∼10 °C) to influence the mass transfer within the membrane contactor, as the composition and flow rate of leaving streams were almost identical to that of the RadFrac model. A process intensification factor analysis showed that membrane contactor technology could reduce the volume of equipment required by a magnitude of 44 to undertake the same carbon capture ratio as the conventional column process.

“…Hence, developing robust membrane models validated with experiments is essential to minimise the R&D costs and accelerate the technology transition. Several mathematical models have been developed for CO 2 /H 2 separation in integrated gasification combined cycle process [178][179][180][181]. By counting that CH 4 behaving more inert than CO 2 in membrane separation [57], these models will be the valuable resources for the process development of hydrogen purification from HENG.…”

The global energy market is in a transition towards low carbon fuel systems to ensure the sustainable development of our society and economy. This can be achieved by converting the surplus renewable energy into hydrogen gas. The injection of hydrogen (⩽10% v/v) in the existing natural gas pipelines is demonstrated to have negligible effects on the pipelines and is a promising solution for hydrogen transportation and storage if the end-user purification technologies for hydrogen recovery from hydrogen enriched natural gas (HENG) are in place. In this review, promising membrane technologies for hydrogen separation is revisited and presented. Dense metallic membranes are highlighted with the ability of producing 99.9999999% (v/v) purity hydrogen product. However, high operating temperature (⩾300 °C) incurs high energy penalty, thus, limits its application to hydrogen purification in the power to hydrogen roadmap. Polymeric membranes are a promising candidate for hydrogen separation with its commercial readiness. However, further investigation in the enhancement of H 2 /CH 4 selectivity is crucial to improve the separation performance. The potential impacts of impurities in HENG on membrane performance are also discussed. The research and development outlook are presented, highlighting the essence of upscaling the membrane separation processes and the integration of membrane technology with pressure swing adsorption technology.
