Abstract
The present invention provides a novel process for the removal and recovery of penicillin and organic acids from process streams and waste waters. The process of the present invention utilizes a combination of a supported liquid membrane (SLM) and a strip dispersion to improve extraction of the penicillin and organic acids while increasing membrane stability and reducing processing costs.
Claims15
A combined supported liquid membrane (SLM)/strip dispersion process for the removal and recovery of one or more target species selected from penicillin G, penicillin V, phenylalanine, acrylic acid, lactic acid, propionic acid, citric acid, acetic acid, and combinations thereof from a feed solution containing the target species comprising
- (1) treating a feed solution containing one or more target species on one side of the SLM embedded in a microporous support material to remove the target species by the use of a strip dispersion on the other side of the SLM, the strip dispersion being formed by dispersing an aqueous strip solution in an organic liquid comprising an extractant, using a mixer;
- and
- (2) allowing the strip dispersion or a part of the strip dispersion to separate into two phases, the organic liquid phase and the aqueous strip solution phase containing a concentrated solution of the target species.
