Jeffrey Scott Kanel, Scott Arthur Guelcher: Method for rupturing microalgae cells. Eastman Chemical Company, Harry J Gwinnell, Cheryl J Tubach, December 14, 1999: US06000551 (46 worldwide citation)

A method for rupturing microalgae in an aqueous suspension is disclosed. In one embodiment the aqueous suspension is passed through a constriction into a liquid phase at a pressure sufficient to rupture the cells by circulating the aqueous suspension through a constriction in a pump loop at a pressu ...

A process and system are disclosed for recovering mixed carotenoids from the alga Dunaliella salina. The harvested cells are ruptured, typically by circulating the algal suspension at high pressure through a pump loop. The cells can then be dewatered by absorptive bubble separation techniques, inclu ...

Scott Arthur Guelcher, Jeffrey Scott Kanel: Method for dewatering microalgae with a bubble column. Eastman Chemical Company, Morgan Lewis & Bockius, June 8, 1999: US05910254 (34 worldwide citation)

A process for dewatering an aqueous suspension of microalgae is disclosed in which the aqueous suspension of the algae is introduced into a bubble column or a modified bubble column for generating a froth of bubbles and adsorbed algal cells that can be separated from the aqueous suspension. In one a ...

Scott Arthur Guelcher, Jeffrey Scott Kanel: Method for dewatering microalgae with a jameson cell. Eastman Chemical Company, Charles R Martin, July 7, 1998: US05776349 (16 worldwide citation)

Methods are disclosed for dewatering an aqueous suspension of microalgae, especially Dunaliella salina, with a Jameson cell. The algal cells are ruptured sufficiently to promote froth flotation of the cells from the suspension. The algal suspension is introduced into the top of the Jameson cell down ...
