PROCESS
Koch Modular Process Systems has extensive experience in process optimization related to extracting components from solutions which either are to difficult or cannot be economically separated through distillation.
PROBLEM and SOLUTION
Client engaged Koch Modular to purify its product from a toluene solution and remove an Aniline Compound impurity. Koch modular initially attempted pilot testing utilizing a Scheibel © Column due to good density differences between the toluene feed phase and the aqueous phase solvent.
However, during initial testing with the organic phase continuous and dispersed aqueous phase, excessive coalescing of the aqueous droplets on the metal internals led to poor column operation.
Pilot testing switched to the KARR ®Column using PTFE plates, allowing for excellent operation with the aqueous phase continuous while also providing the optimal direction of mass transfer.
RESULTS
Following successful pilot testing, Koch Modular designed a KARR® Column tailored to client’s feedstock wetting characteristics delivering the required specification of less than 1 part per million of the aniline compound within the raffinate.
