While the actual synthesis represents the know-how of our customers, the handling of the assisting media and waste flows is a task that we are happy to take over for you. At the same time, the following goals must take center stage. Materials must be recycled with the necessary purity in order to be recovered in the processes and the escaping flows may not exceed the limit values set by the authorities. Our processes are based on the knowledge of thermal separation and long-term experience in plant engineering.

• 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)
• Production of absolute alcohol by extractive or azeotropic distillation
• Recovery of organics by solvent extraction: phenol, pyridine, DMF, NMP
• Recovery of metal salts and acides by solvent extraction: acetic acid, thioglycolic acid; iron-3-chloride, ammonium molybdate
• Dehydration of organics (amines, THF) by caustic packed bed adsorption
• Purification of natural extracts (e.g. essential oils)
