Evaporators and Reboilers - Enerquip

In a rising film evaporator, the liquid being evaporated is fed into long tubes and heated with steam on the outside of the tube (from the shell side). This produces steam and vapor within the tubes and brings the liquid in the tubes to a boil. The vapor produced creates a thin film that rises.

Rising Film Evaporators - Swenson Technology

In rising film evaporators, liquid enters the bottom of the tubes and is heated to boiling. The expansion of the vapor carries the liquor out the top of the tube, where the resulting vapor and liquid are separated. Rising film evaporators are used in many applications because the system is mechanically simple with few pumps and has relatively ...
