Evaporation / Rectification

Evaporation & rectification applications

Film evaporators powered by corosys – these are mostly Falling Film Evaporators (EFF) and Thin Film Evaporators (ETF), also in combination with rectification tops, as well as Short Path Evaporators (ESF) – are used for distillative purification, fractionation or removal of unwanted highly volatile by-products or starting materials. Typically, the evaporated substances have molecular weights between 100 kg/kmol to 500 kg/kmol and beyond.Fatty acids, fatty acid derivates and by-products from the production of edible oil

• Omega-3 fatty acid ethyl ester, concentration and separation
• Fatty acid monoesters of glycerol (emulsifiers) and their derivatives (tartrates, citrates)
• MCTs (medium chain triglycerides)
• Pesticide removal from oils and fats
• Fatty acids from edible oils and from tall oil
• Resin acids from tall oil
• Dimer fatty acids
• Other fatty acid derivatives, e.g. amides
• Lecithin
• Phytosterols
• Natural tocopherols and tocotrienols
• Carotene
• Squalene

Special polymers or oligomers

• Polyurethane prepolymers from di-isocyanates (TDI, HDI, MDI, IPDI etc.) and polyols
• Polyethers (terathanes, polyethylene glycols)
• Polysiloxanes and derivatized polysiloxanes
• Epoxy resins, e.g. bisphenol A and F Diglycidether

Pharmaceuticatl and cosmetic products

• Cannabinoids (CBD, THC)
• Fungicides
• Pharmaceutical glycerine
• Vitamin E acetate
• UV absorbers
• Lanolin
• Carnauba wax

Mineral oil products

• Hard waxes (fractionation)
• Recycling of lubricants
• Vacuum pump oils

Fragrances and Flavourings

• Agrum oils (limonene removal, Nootkaton, Valencen, etc.)
• Patchouli oil (fractionation and colour improvement)
• Vetiver oil, oil of guaiac, labdanum oil
