To better capture CO\u003Csub\u003E2\u003C\/sub\u003E, the researchers will cool and pressurize the flue gases.\u003C\/p\u003E\u003Cp\u003EHistorically, it\u2019s been believed that it would be too costly to treat the flue gases in this fashion, Lively explains, because power plants release so much CO\u003Csub\u003E2\u003C\/sub\u003E into the atmosphere \u2013 9 to 10 tons per minute.\u003C\/p\u003E\u003Cp\u003E\u201cHowever, our team has devised ways to efficiently recover the energy required to cool and compress the flue gases,\u201d he says.\u003C\/p\u003E\u003Cp\u003ECooling the gas will enable highly efficient operation of pressure swing adsorption systems that employ metal organic frameworks supported by hollow fiber sorbents, which create more compact gas-separation devices.\u003C\/p\u003E\u003Cp\u003E\u201cWe\u2019re rethinking the way we remove CO\u003Csub\u003E2\u003C\/sub\u003E from power plants,\u201d Lively says. \u201cThrough novel process engineering, state-of-the-art materials that remove CO\u003Csub\u003E2\u003C\/sub\u003E can perform 10 times better than they would at ambient conditions.\u201d\u003C\/p\u003E\u003Cp\u003EThe other project funded by DOE \u2013 spearheaded by ChBE\u2019s Ryan Lively and collaborators at Praxair, Inc. (an industrial gas company) \u2013 is titled \u201cImproving Energy Efficiency of Air Separation via Hollow Fiber Sorbents.\u201d It will last for 18 months (total funding: $1,174,277) and involve ChBE faculty members Christopher Jones, William Koros, and Matthew Realff.\u003C\/p\u003E\u003Cp\u003EThe project aims to improve the industrial energy efficiency of gas separation technology associated with the creation of CO\u003Csub\u003E2\u003C\/sub\u003E and hydrogen.\u003C\/p\u003E\u003Cp\u003EKnown as \u201cpre-combustion CO\u003Csub\u003E2\u003C\/sub\u003E capture,\u201d the technology involves gasifying the fuel for power production into hydrogen and CO\u003Csub\u003E2\u003C\/sub\u003E at high pressures. This high-pressure CO\u003Csub\u003E2\u003C\/sub\u003E is easier to capture than the low-pressure CO\u003Csub\u003E2\u003C\/sub\u003E found in power plant flue gas.\u003C\/p\u003E\u003Cp\u003E\u201cOne of the major issues with this approach is the need to separate large quantities of air to assist in the gasification process,\u201d Lively explains.\u003C\/p\u003E\u003Cp\u003ETo make this large-scale air separation technology economically attractive, the researchers will develop and test a rapidly cycled pressure swing adsorption (RCPSA) system for separating the gases up to five times more efficiently than traditional cryogenic technology. The sub-ambient-temperature RCPSA system will involve advanced zeolites supported by hollow fiber sorbents.\u003C\/p\u003E\u003Cp\u003ETogether, these two new DOE funded projects will support four post-doctoral researchers and four graduate students in ChBE at Georgia Tech.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"ChBE Researchers Win DOE Awards for Projects to Reduce CO2 Emissions"}],"field_summary":[{"value":"\u003Cp\u003EResearchers in Georgia Tech\u2019s School of Chemical \u0026amp; Biomolecular Engineering (ChBE) have won two grants from the Department of Energy (DOE) for projects designed to enhance the operational efficiency of systems that reduce carbon dioxide emissions from power plants.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"ChBE Researchers Win DOE Awards for Projects to Reduce CO2 Emissions"}],"uid":"27271","created_gmt":"2015-09-16 11:06:02","changed_gmt":"2016-10-08 03:19:33","author":"Brad Dixon","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2015-09-16T00:00:00-04:00","iso_date":"2015-09-16T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"448671":{"id":"448671","type":"image","title":"Ryan Lively","body":null,"created":"1449256264","gmt_created":"2015-12-04 19:11:04","changed":"1475895189","gmt_changed":"2016-10-08 02:53:09","alt":"Ryan Lively","file":{"fid":"203272","name":"lively_3.jpg","image_path":"\/sites\/default\/files\/images\/lively_3_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/lively_3_0.jpg","mime":"image\/jpeg","size":3236788,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/lively_3_0.jpg?itok=5O0bzozr"}}},"media_ids":["448671"],"groups":[{"id":"1240","name":"School of Chemical and Biomolecular Engineering"}],"categories":[{"id":"141","name":"Chemistry and Chemical Engineering"},{"id":"154","name":"Environment"}],"keywords":[{"id":"7508","name":"carbon dioxide"},{"id":"141451","name":"Chemical and Biomolecular Energy"},{"id":"663","name":"Department of Energy"},{"id":"464","name":"emissions"},{"id":"109","name":"Georgia Tech"},{"id":"138601","name":"power plants"},{"id":"96231","name":"Ryan Lively"}],"core_research_areas":[{"id":"39531","name":"Energy and Sustainable Infrastructure"}],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EBrad Dixon (\u003Ca href=\u0022mailto:braddixon@gatech.edu\u0022\u003Ebraddixon@gatech.edu\u003C\/a\u003E), 404-385-2299\u003C\/p\u003E","format":"limited_html"}],"email":["braddixon@gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
