Welded plate exchangers mainly for use in the chemical industry or for utility systems in large buildings. The most energy-intensive process heating application in a refinery is the crude preheat train. This is where raw crude is heated to separate components in the atmospheric distillation unit.

Plate heat transfer surfaces are the latest development in falling film technology. Various configurations of plates have been tried in the past. Among them have been dimpled plates and corrugated plates. The latest type of plates are pressed plate used in a falling film (PPFF). This new configuration has several advantages never before available to any seawater desalination process.

Common heat exchangers used in these process sections are often dirty and blocked. Therefore, the use of wide-channel heat exchangers in these process sections is not easy to be dirty and blocked, and the cleaning cycle is longer.
