Assessment on the Application of Facilitated Transport Membranes in Cement Plants for CO2 Capture

Carbon dioxide capture from cement plant flue gas can play an important role in mitigating CO2 emission that lead to climate change. Among all the technologies evaluated, membranes have potential to be one of the most energy-efficient and low-cost CO2 capture option. In this work, a novel membrane technology, Facilitated Transport Membranes (FTMs), is assessed to further reduce energy demand and cost for CO2 capture in a cement plant. A new process that employs FTMs is simulated and applied to a real clinker production plant in Italy (Colacem, Gubbio). The process is then compared with other carbon capture technologies. Results show that the FTM technology can be competitive with other technologies despite the need of steam to operate the membrane. Despite the benefit in terms of specific emission compared to more established absorption with liquid amines process, further improvements on membrane performances are needed to gain also an economic advantage for carbon capture in the cement industry.

Automated summary

Carbon dioxide capture from cement plant flue gas using Facilitated Transport Membranes (FTMs) can reduce energy demand and costs, although steam is required to operate the membrane. Despite the need for steam, FTMs technology shows competitiveness with other carbon capture technologies, but further improvements in membrane performance are necessary for economic advantage in the cement industry.
