Falling Film Evaporators by Buss-SMS-Canzler GmbH

The falling film principle requires an even distribution of the feed liquid. To achieve this distrubution one or more distribution trays are located in the top head of the evaporator over the complete tube sheet.
Our proven distribution devices make sure that the inner surface of each individual tube is properly wetted.
The liquid film moves down the tubes by gravity force. Heat applied through the tube wall effects boiling-off the light fraction from the film. The picture shows a co-current operating evaporator with vapour and liquid leaving the bottom of the evaporator into the separator vessel.

Falling Film Evaporators for Special Applications
Low Pressure Design

Low pressure falling film evaporators operate below 5 mbar abs with co-current or counter-current vapour and liquid flow.

Typical applications are:

Oleo-Chemical Industry (Fatty acids, Monogylcerides)
Chemical Industry (Silicone, MDI, Caprolactam)

Whitlock Evaporator
Whitlock evaporators are single stage air swept falling film evaporators with dried hot air blown counter-currently to the liquid flowing down inside the tubes. The dry air improves mass transfer for low moisture content in the product. Whitlock evaporators typically serve in the fertilizer industry for dehydration of:

Ammonium Nitrate
Urea

The resulting melt can be processed directly in a prill tower to obtain dry granulates.

The advantages of the Whitlock Evaporator are:

large capacities up to 2,000 metric ton per day
moisture content down to 0.1 % water
atmospheric operation
high turn-down ratio
easy to operate
low maintenance cost
