Rising/Falling Film Plate This is the original plate type evaporator. The principle of operation for the rising/ falling film plate evaporator (RFFPE) involves the use of a number of plate packs or units, each consisting of two steam plates and two product plates. These are hung in a frame which resembles that of a plate heat exchanger (Figure 8).

Heat recovery from warm water is most profitable if the pulp and paper mills form an integrated whole – as in Kaukas, where heat recovery at the pulp mill saves steam for use in the paper mill. Process integration is key to cooling warm water flows in pulp mill processes, without the need for condensing towers, resulting in energy savings and improved energy economics.

Aug 11, 2017 · For instance, a material may require heat treating before being formed cold in a plate roll, but the mill or other material supplier may have a backlog. So in some cases, a roll shop receives as-rolled plate (without heat treating) and, via hot rolling, performs the necessary heat treatment.
