Falling film evaporation plant for caprolactam
GEA Wiegand

  • falling film evaporation plant for caprolactam GEA Wiegand
One of the most important fibers, polyamide 6, is produced by polymerization of caprolactam. Large quantities of extraction effluents are produced in this process. The effluents are cleaned in evaporation plants: the valuable substance is recovered, waste products are minimized, and existing energies from the caprolactam production can be used.

Moreover, evaporation plants are used in this process as sump evaporators for distillation plants.

The particular features of GEA Wiegand plants are:

Economic conception in order to minimize the caprolactam losses
Long operating periods thanks to an optimum temperature
Many years of experience in the application of mechanical vapor recompressors
