Special Issue Information

Dear Colleagues,

The recent SPIRE initiatives developed in the framework of H2020 calls to define CO2 separation and reuse as one of the most important pillars to boost sustainability, making the chemical industry competitive, while at the same time contributing to climate change mitigation. Membrane technologies can find many applications, both in CO2 separation and in its conversion. CO2 separation from flue gas coming out from a power plant or the cement industry, as well as CO2 from biogas and natural gas are some of the fields where membrane gas separation finds application. Moreover, membrane reactors are recently competing as good candidates for CO2 conversion for valuable fuels or chemicals.

To this purpose, membrane engineering, together with materials science, play a key role in the development of membrane technologies as CO2 alternative processes become more compact and efficient, with a lower energy consumption, a reduced plant volume, and are well-fit to the Process Intensification Strategy.

Within this context, this Special Issue aims at compiling relevant contributions showing the recent advances of membrane technologies in CO2 separation and reuse. Modeling and experimental manuscripts, as well as reviews dealing with the most significant technologies, are particularly welcome.

Natural gas sweetening is required to remove the acid gas CO2 to meet gas grid specifications. Membrane technology has a great potential in this application compared to the state-of-the-art amine absorption technology. Carbon membranes are of particular interest due to their high CO2/CH4 selectivity of over 100. In order to document the advantages of carbon membranes for natural gas (NG) sweetening, HYSYS simulation and cost evaluation were conducted in this work. A two-stage carbon membrane process with recycling in the second stage was found to be technically feasible to achieve >98% CH4 with <2% CH4 loss. The specific natural gas processing cost of 1.122 × 10−2 $/m3 sweet NG was estimated at a feed pressure of 90 bar, which was significantly dependent on the capital-related cost. Future work on improving carbon membrane performance is required to increase the competitiveness of carbon membranes for natural gas sweetening. Full article

Title: Performance of Hollow-Fibre Thermally-Rearranged Polymeric Membrane Modules by pairing Computational Fluid Dynamics and Reactive Vacancy Solution Theory
Authors: Adele VACCARO, Carmen RIZZUTO, Giulia AZZATO, Yu SUN, Giuseppe DE MARCO, Elena TOCCI, Alessio CARAVELLA

Abstract:

This work aims at evaluating the overall performance of thermally-rearranged polymeric membrane modules by means of a computational fluid dynamic (CFD) approach taking into account the non-ideal adsorption of multicomponent mixtures in the membrane by the reactive vacancy solution theory (RVST). The technological objective consists in simulating the behaviour of hollow-fibre polymeric membrane modules in conditions close to actual industrial applications. In fact, on the one hand CFD simulations are able to reproduce with good approximation the complex flow field developing among the fibres. On the other hand, the RVST allows us to account for the adsorption of multicomponent gas mixtures in real (non-ideal) conditions of relatively high pressure, where usual approaches based on the Langmuir and Raoult hypotheses, such as the ideal adsorption solution theory (IAST), cannot be applied.
