Reply to 1#: May I ask what material your production equipment is made of? How long can it probably be used? What problems have occurred during usage?

Reply to 3# jscf: Some factories also use defoamers; for example, Shandong Haihua has used them before. However, if not controlled properly, they can affect the particle size of liquid-phase hydrated soda ash.
Reply to 4# dt798346317: Your question is too vague. The equipment used in soda ash production is quite complex. Among the pumps, there are titanium pumps, screw compressors, water-ring vacuum pumps, etc. As for vessels, there are various types of towers and tanks. There are also industrial furnaces such as lime kilns and calcination furnaces. In terms of materials, there’s carbon steel, stainless steel, titanium, and so on. In terms of equipment management, the main issues involve routine maintenance and usage; corrosion prevention is a relatively important aspect. I’m not sure if this will be helpful to you.
Reply to 5# zhaitonglan: There are many types of conveying pipes used in soda ash plants. The most common ones are cast iron pipes and carbon steel pipes. There are also stainless steel pipes, 15CrMo pipes, 20g pipes, fiberglass pipes, as well as PVC, PE, RPP, and reinforced MC nylon pipes. It mainly depends on the need to consider investment costs while taking different production media into account.

Since phase changes are involved, I’m not sure where to start. It would be fine even if it’s just the heat balance calculation for a single external cooler! ! ? ?

Hello, do you use graphite heat exchangers?
OP, are you still willing to change jobs? We urgently need talents like you
