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.

  • 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
