In one advantageous embodiment, the bubble column is a multi-stage loop-flow flotation column that has three loop-flow zones, each of which is defined by a draft tube concentrically mounted in the column to divide each loop-flow zone into a riser and the downcomer. Fine bubbles of gas and brine are in cocurrent upward flow in the riser and in cocurrent downward flow the downcomer. A higher gas holdup is promoted in the riser than in the downcomer, thereby circulating the brine in loop-flow upwardly through the riser and downwardly through the downcomer. Liquid communication between adjacent loop-flow zones is substantially eliminated. A froth enriched in algae is generated that can be separated&#8230;<\/p>\n<p>Patent number: 5910254<br \/>Filing date: Dec 20, 1996<br \/>Issue date: Jun 8, 1999<br \/>Inventors: Scott Arthur Guelcher, Jeffrey Scott Kanel<br \/>Assignee: Eastman Chemical Company<\/p>\n<p>More info on this patent <a href=\"http:\/\/www.google.com\/patents?vid=USPAT5910254\">from here<\/a><\/p>\n<p><b><span style=\"color:red;\">Nature <a href=\"http:\/\/www.oilgae.com\/ref\/oil\/or\/or.html\">gave us<\/a> oil from algae; perhaps <a href=\"http:\/\/www.oilgae.com\/ref\/story\/story.html\">we should try<\/a> Nature&#8217;s way again<\/span><\/b><\/p>\n<p><b><a href=\"http:\/\/www.oilgae.com\/\">Oilgae &#8211; Oil &amp; Biodiesel from Algae<\/a><\/b><br \/><b><a href=\"http:\/\/www.oilgae.com\/blog\/\">Oilgae Blog<\/a><\/b>; The <b><a href=\"http:\/\/www.oilgae.com\/blog\/dir\/dir.html\">complete list of Oilgae Blog articles<\/a><\/b>.<br \/><b><a href=\"http:\/\/www.oilgae.com\/algae\/oil\/biod\/research\/os\/algos.html\">algOS &#8211; Biodiesel from Algae Open Source<\/a><\/b><\/p>\n<p>About Oilgae &#8211; <b><a href=\"http:\/\/www.oilgae.com\/\">Oilgae &#8211; Oil &amp; Biodiesel from Algae<\/a><\/b> has a focus on biodiesel production from algae while also discussing alternative energy in general.
