Climbing Film Evaporator - How it works? - Solution Pharmacy

May 07, 2021 In a climbing film evaporator, tubes are heated externally by steam. The preheated feed enters from the bottom and flows up through the heated tubes. The liquid gets heated rapidly due to the enhanced overall coefficient of the preheated feed.) The liquid near the wall becomes vapor and forms small bubbles. These tend to fuse to larger bubbles ...

There are two main types of long-tube vertical evaporators: climbing-film and falling-film. In both types feed enters the evaporators through tubes, is heated and part of it evaporates. The vapor is then recovered. In climbing film evaporators the liquid enters from the bottom, while in falling film types it enters from the top.
