CO2 Removal from Natural Gas

This project will develop an enzyme-catalyzed, contained liquid membrane reactor for removal of CO2 from natural gas. The membrane will be capable of achieving both high flux and high separation factor while reducing fouling. This is a specific example of the enrichment of a dilute gas stream. Ultimately, a biomimetically derived membrane will be capable of selectively removing CO2 from mixed gas streams where the CO2 is < 50%. Phase I will develop the membrane system and begin a parametric performance evaluation. Initially, CO2/CH4 mixtures will be used. The data will be analyzed by mass spectrometry. Thereafter, more complex mixtures, along with natural samples of natural gas and landfill gas, will be tested. Phase II field tests will demonstrate efficacy.
