variable thin-film evaporator
combination of thin-film
evaporation and rectification
Scope
- Design of the thin-film evaporator with attached rectification column (RKW4)
- Additional separation stages by combining the two processes (8 < Nth < 40)
- Special distillation process by forming a thin film of liquid
- Product-friendly process due to short retentiontime
- Distillate, middle distillate and bottom product
Operation parameter
- feed-rate: up to 4 L/h, continous
- pressure: vacuum (0,01 mbar) up to atmospheric pressure
- temperature: ambient temp. up to 200 °C
- glass version with PTFE-rollers
short-path evaporator
in three designs
Scope
- short-path distillations (e.g. FAME)
Operation parameter
three designs, continuous operation
- feed-rate: up to 3 L/d
- pressure: vacuum (0,01 mbar) up to atmospheric pressure
- temperature: ambient temp. up to 160 °C
