Latest Patents
Sidsel Thelander's latest patents focus on a process and apparatus for flow injection extraction. This innovative method allows for the extraction of a substance dissolved in a first solvent into a second solvent that is insoluble in the first. The design utilizes a T-tube with two legs to bring the solvents together, allowing the mixture to exit through a third leg. The cross-sectional areas of the legs are specifically dimensioned to create segmented flow, alternating plugs of the two solvents. The optimal ratio between the cross-sectional areas of the tube legs for the first and second solvents is between 2-8:1, with a preferred ratio of 4:1. Additionally, the ratio between the first and third legs is adjusted to 0.7-1.2:1, ideally 1:1, at a distance from the juncture that is 1-3 times the inner diameter of the third leg. This design leads to a powerful extraction due to counter-current turbulence created by the flow through a spiral hose.
