DEA Wiped Film and Short Path Distillation Plants Feature
DEA Wiped Film and Short Path Distillation Plants Feature:
- High Turbulence in a Wiped Film for High Mass and Heat Transfer
- Short Residence Time for Low Thermal Stress of the Products
- Evaporation in One Pass , No Circulation
- Small Film Thickness , No Hydrostatic Height
- No Product Fouling on the Heated Evaporator Wall Due to High Turbulence of Wiped Film
- High Turndown Ratio , High Flexibility for Variation in Requirements
- Distillation of High Viscosity Products by Special Designed Wiper Systems
- Low operating pressure Down to One Micron to Decrease Boiling Temperature
Short-Path and Wiped-Film Technologies are used for:
- Distillation of products which can only be distilled at a very high temperature under atmospheric pressure and where distillate and residue has to be discharged from the distillation in a very short time
- Reaction and/or distillation where heat sensitive products are feedstock, product or side product (e.g. vitamins)
- For thermal reactions that will run very quickly at high temperature and do not allow long residence time in the reactor
- For products with a tendency to spontaneously decompose
