Please provide a written description of the process flow for the evaporation section!

Newcomers to the chlor-alkali industry find that the piping in the evaporation section is complex and there are numerous valves. It’s confusing after reading it; now I want to understand and master it by combining written descriptions of the process flow with flowcharts! The flowchart is available, but there is a lack of textual description. # + + .
You didn’t mention what type of evaporation it is; how can I describe it then? It’s about what the initial concentration is, what it becomes in the end, and which process to use.
Very precise numerical parameters are not required; it is only necessary to describe the process flow. It’s a textual description of the process. Which device is connected to which, and the direction of the pipes.
Different processes are different: dizzy:

Electrolyte: Tank -- Pump -- Preheater -- First-stage evaporation -- Pump -- Second-stage evaporation -- Pump -- Third-stage evaporation -- Alkali overflow tank. Steam: Raw steam -- First-stage evaporation -- Condensation; Steam from first-stage evaporation -- Second-stage evaporation -- Condensation; Steam from second-stage evaporation -- Third-stage evaporation -- Condensation; Steam from third-stage evaporation (vacuum pump) -- Circulating water. Ion exchange membrane: 32 to 50; countercurrent operation in the second stage. Alkali solution: Tank -- Pump -- First-stage evaporation -- Pump -- Second-stage evaporation -- Heat exchanger -- Second-stage evaporation -- Pump -- Heat exchanger -- Heat exchanger -- Tank. Steam: Raw steam -- Second-stage evaporation -- Condensation; Steam from second-stage evaporation -- First-stage evaporation -- Condensation. There are significant differences among various processes; the above are only brief examples
Reply to 5# smartcatii: Although it’s not the result I wanted, it’s still a bit helpful. .
Then you need to post your manufacturing process as well in order to help explain it
As the saying goes, pictures speak louder than words; if you post your pictures, I believe you will get what you want. Different manufacturing processes result in different descriptions, and it is only with pictures that the truth can be revealed!
