3D printed modular centrifugal contactors and method for separating moieties using 3D printed optimized surfaces
The present invention provides an annular centrifugal contactor, having a housing to receive a plurality of liquids; a rotor inside the housing; an annular mixing zone, with a plurality of fluid retention reservoirs; and an adjustable stem that can be raised to restrict the flow of a liquid into the rotor or lowered to increase the flow of liquid into the rotor. The invention also provides a method for transferring moieties from a first liquid to a second liquid, the method having the steps of combining the fluids in a housing whose interior has helically shaped first channels; subjecting the fluids to a spinning rotor to produce a mixture, whereby the channels simultaneously conduct the mixture downwardly and upwardly; and passing the mixture through the rotor to contact second channels, whereby the channels pump the second liquid through a first aperture while the first fluid exits a second aperture.
1. An annular centrifugal contactor, said annular centrifugal contactor comprising:
a) a housing adapted to receive a plurality of flowing liquids;
a hollow rotor coaxially positioned within the housing, the rotor defining a first open depending end, and a second open upwardly facing end, wherein medially facing surfaces of the hollow rotor define first fluid flow enhancing topographies;
b) an annular mixing zone defined by the housing and a vane plate,
wherein the annular mixing zone has a plurality of fluid retention reservoirs with ingress apertures near the bottom of the annular mixing zone and egress apertures located above the ingress apertures of the annular mixing zone; and
c) an adjustable vane plate stem, wherein the stem can be raised to restrict the flow of a liquid into the rotor or lowered to increase the flow of the liquid into the rotor.
2. The annular centrifugal contactor of claim 1 , wherein the first fluid flow enhancing topographies comprise helically shaped channels positioned along longitudinally extending surfaces of the hollow rotor.
3. The annular centrifugal contactor of claim 1 , wherein a plurality of baffles are disposed within each fluid retention reservoir.
4. The annular centrifugal contactor of claim 1 , wherein the second open upwardly facing end comprises regions defining fluid flow enhancing grooves.
5. The annular centrifugal contactor of claim 1 , wherein each of the fluid retention reservoirs are jacketed with a volume enclosing a flowing heat transfer fluid.
6. The annular centrifugal contactor of claim 1 , wherein a plurality of baffles extend from a surface of each of the fluid retention reservoirs.
7. The annular centrifugal contactor of claim 1 , wherein the annular mixing zone is impregnated with a catalyst, reactant, adsorbent, or a combination thereof.
8. The annular centrifugal contactor of claim 1 , wherein the adjustable vane plate stem is adapted to serve as a needle valve and drain tube.
9. The annular centrifugal contactor of claim 1 , wherein the adjustable vane plate stem is in mechanical communication with a mechanized assembly such that the adjustable vane plate stem is adjusted up and down using the mechanized assembly.
