Abstract
A solvent mixing system includes a mixing tee, a centrifugal mixing path, and a low frequency blending mixer. The mixing tee has at least two solvent input ports and a solvent output port in fluid communication with one another. The centrifugal mixing path has a mixing path inlet in fluid communication with the solvent output port of the mixing tee. The centrifugal mixing path includes at least one coiled segment between the mixing path inlet and a mixing path outlet. The low frequency blending mixer is in fluid communication with the outlet of the centrifugal mixing path.
Claims8
A solvent mixing system comprising:
- a mixing tee having at least two solvent input ports and a solvent output port in fluid communication with one another;
- a centrifugal mixing path having a mixing path inlet in fluid communication with the solvent output port of the mixing tee, the centrifugal mixing path including at least one coiled segment between the mixing path inlet and a mixing path outlet;
- and
- a low frequency blending mixer in fluid communication with the outlet of the centrifugal mixing path, wherein the low frequency blending mixer is a single inlet mixer and comprises:
- a mixer input port in fluid communication with the outlet of the centrifugal mixing path;
- a first filter/retainer located downstream of the mixer input port;
- a mixing chamber;
- and
- a second filter/retainer located downstream of the mixing chamber.
