Their approach used ambient wind flow to draw air across a new kind of coated carbon fiber to grab CO2. That would eliminate the loud fans used in many systems. And the carbon fiber strands could be quickly heated to release the captured carbon dioxide with minimal heat loss, boosting efficiency.</p> <p>But they were struggling with how to deploy these new sorbent-coated carbon fibers for maximum effect.</p> <p>“I had to go deposit a check at the bank, and I went through the drive-through. They had the old pneumatic tubes that come down to transport documents,” said <a href="https://chbe.gatech.edu/people/ryan-p-lively">Ryan Lively</a>, Thomas C. DeLoach Professor in Georgia Tech’s <a href="https://chbe.gatech.edu/">School of Chemical and Biomolecular Engineering (ChBE)</a>. “There are not many times you have a light bulb moment in your career, but I saw the tubes and I realized, we could put the fibers in something like a bank teller tube canister.</p> <p>“That’s pretty much what we did, and it worked.”</p> <p><a href="https://coe.gatech.edu/news/2023/06/inside-out-heating-and-ambient-wind-could-make-direct-air-capture-cheaper-and-more"><strong>Read the full story on the College of Engineering website.</strong></a></p></div> <div> <div> <p>Subtitle</p> </div> <div><br> <br> </div> </div> <div> <div> <p>Summary sentence</p> </div> <div>Chemical engineers use coated carbon fibers and eliminate steam-based heating in their simpler design, which also can be powered by wind energy.</div> </div> <div> <div> <p>Summary</p> </div> <div><p>Chemical engineers use coated carbon fibers and eliminate steam-based heating in their simpler design, which also can be powered by wind energy.</p></div> </div> <div> <div> <p>Dateline</p> </div> <div><time datetime="2023-06-12T12:00:00Z">Mon, 06/12/2023 - 12:00</time> </div> </div> <div> <div> <p>Email</p> </div> <div>jstewart@gatech.edu</div> </div> <div> <div> <p>Contact</p> </div> <div><p><a href="mailto:jstewart@gatech.edu">Joshua Stewart</a><br> College of Engineering</p></div> </div> <div> <div> <p>Associated importer</p> </div> <div>1</div> </div> <picture> <img loading="lazy" src="http://www.gatech.edu/sites/default/files/hg_media/_MG_1910%28edited%29.jpg" width="5088" height="3392" alt> </picture> <div> <div> <h4>Keywords</h4> </div> <div class="hg-link-container"> <div class="mb-3 float-left"> <a class="hg-link" href="http://www.gatech.edu/news/keywords/direct-air-capture">Direct air capture</a> </div> <div class="mb-3 float-left"> <a class="hg-link" href="http://www.gatech.edu/news/keywords/direct-air-capture-technology">direct air capture technology</a> </div> <div class="mb-3 float-left"> <a class="hg-link" href="http://www.gatech.edu/news/keywords/carbon-fiber">carbon fiber</a> </div> <div class="mb-3 float-left"> <a class="hg-link" href="http://www.gatech.edu/news/keywords/ryan-lively">Ryan Lively</a> </div> <div class="mb-3 float-left"> <a class="hg-link" href="http://www.gatech.edu/news/keywords/christopher-jones">Christopher Jones</a> </div> <div class="mb-3 float-left"> <a class="hg-link" href="http://www.gatech.edu/news/keywords/matthew-realff">Matthew Realff</a> </div> <div class="mb-3 float-left"> <a class="hg-link" href="http://www.gatech.edu/news/keywords/chemical-and-biomolecular-engineering">chemical and biomolecular engineering</a> </div> <div class="mb-3 float-left"> <a class="hg-link" href="http://www.gatech.edu/news/keywords/go-sei">go-sei</a> </div> <div class="mb-3 float-left"> <a class="hg-link" href="http://www.gatech.edu/news/keywords/go-researchnews">go-researchnews</a> </div> </div> </div> <div> <div> <h4>News room topics</h4> </div> <div class="hg-link-container"> <div class="mb-3 float-left"> <a class="hg-link" href="http://www.gatech.edu/news/topic/earth-and-environment">Earth and Environment</a> </div> </div> </div> <div> <div> <p>Mercury ID</p> </div> <div>668077</div> </div> <div> <div> <p>Source updated</p> </div> <div><time datetime="2023-06-14T14:53:13-04:00">Wed, 06/14/2023 - 14:53</time> </div> </div> Thu, 15 Jun 2023 07:57:57 +0000 admin 28426 at http://www.gatech.edu
