Fabrication and Scale-Up of Polybenzimidazole-Based Membrane System for Pre-Combustion Capture of Carbon Dioxide
Project No.: FC26-07NT43090
SRI International is developing a high-temperature polymer membrane and designing a membrane module for pre-combustion capture of carbon dioxide (CO2) from integrated gasification combined cycle (IGCC)-derived synthesis gas (syngas). The membrane utilizes polybenzimidazole (PBI) fiber, a synthetic fiber with a very high melting point that also does not readily ignite, because of its exceptional thermal and chemical stability.
The overall goal of this project is to develop a pre-combustion capture system that is capable of operation under a broad range of conditions relevant to the power industry while meeting the U.S. Department of Energy's Carbon Sequestration Program goals of 90 percent CO2 capture at less than a 10 percent increase in the cost of energy services.
