Distillation in Pharmaceutical Industry

The number of solvents handled in this area of application (distillation) is particularly large and the range in plant capacity is considerable. Depending on the type of processing, plants may be required with a distillation capacity of just a few hundred liters right up to several tons per hour. When integrating existing processes, sterile processing can be equally important as taking into consideration any special explosion protection guidelines. Standard solutions are out of the question. Specific processing stages such as evaporation, distillation, rectification, stripping, and condensing are applied according to particular requirements and are combined to provide the best possible results.

GEA Evaporation Technologies (GEA Wiegand) has extensive experience of a wide variety of materials, so that, in the majority of cases, reference can be made to previously designed plants.

Areas of Application of Distillation

• hexane recovery from MIBK, solid matter and oil mixtures
• dimethylacetamide recovery and concentration of residue
• concentration of antibiotics with methanol recovery
• butanol recovery from broth extracts
• recovery of ethylacetate/isopropylacetate
• concentration of isopropanol from extraction solvents
