Project Summary

The project objective is to test and validate improvements to CO2 capture using membrane technology. The results will be essential for significantly reducing future commercial CCS project costs by facilitating appropriate material selection and process design. This project will build on the research capacity for fabrication of defect free polymeric hollow fibre membranes with a range of selectivity and permeance and evaluation of membrane performance due to aging and plasticization.

Evaluation of CO2 capture with high performance hollow fiber membranes from flue gas - Final Report

The research team developed and tested, with both lab and onsite conditions, two generations of hollow fibre membranes. Improved CO2 separation performance was achieved with the first generation membrane compared with existing membranes, while the second generation composite membrane achieved excellent separation performance with potential to make a membrane process competitive for CO2 capture.  On-site test results for both generation membranes demonstrated that the stable membrane separation performance could be achieved but performance was severely impacted when subjected to flue gas without pre-treatment.  Flooding of the membrane module by condensed water in the pipeline could cause irreversible damage to the membrane fibers. These observations suggest that pre-treatment of flue gas, particularly removal of water is essential prior to feeding to the membrane system.
