All around the actual synthesis material flows accumulate in the chemical and pharmaceutical industry, which must be cleaned under environmental aspects or still contain resources. At the same time, the requirements of the environmental protection laws also must be adhered to as well as the cost-saving preparation and recycling of resources.
In the scope of our process system activities we can offer you engineering services in different project levels up to turn key delivery

Product Recovery and Product Purification

• Solvent recovery by evaporation, distillation and rectification like MDC, NMP, DMF, alcohols,
  Cleaning Solvent, etc.
• Rectification of binary and multi-component mixtures (e.g. epichlorhydrin)
