20140059922 | PROCESS FOR PRODUCING BIODIESEL THROUGH LOWER MOLECULAR WEIGHT ALCOHOL-TARGETED CAVITATION - A method for producing fatty acid alkyl esters from biolipids through transesterification and/or esterification reactions uses a flow-through cavitation device for generating cavitation bubbles in a fluidic reaction medium. The fluidic medium is passed through sequential compartments in the cavitation device having varying diameters and inner surface features to create localized reductions in fluid pressure thus vaporizing volatile alcohols and creating an increased surface area and optimized conditions for the reaction to occur at the gas-liquid interface around the bubbles. | 03-06-2014 |
20150057460 | METHOD FOR CAVITATION-ASSISTED REFINING, DEGUMMING AND DEWAXING OF OIL AND FAT - A method for degumming and/or refining crude oil containing impurities involving mixing the crude oil with degumming agents, i.e., water or acid, and subjecting the mixture to flow-through, hydrodynamic cavitation processing. The cavitational processing transfers impurities in the crude oil to a water phase for easier separation. The water phase may be separated from the oil phase by commonly available separation methods. | 02-26-2015 |

A working chamber disposed between the inlet and the outlet includes alternating radial and central flow guides disposed concentrically in the working chamber about a central axis. A first radial flow guide is disposed proximate to the inlet and all radial flow guides have a radial opening adjacent to an inner wall of the housing. A first central flow guide is disposed proximate to the outlet and has a central opening about the central axis. The alternating concentric nature of the flow guides promotes alternating generation and collapse of cavitational features, all while promoting the efficient exchange of heat between hot zones and cooler regions of adjacent flow guides. | 09-20-2012 |
