Reasons for thinning in the two-stage distillation of the CO2 stripping unit
Thread Content
In CO2 stripping units, what are the reasons why the body of the two-stage evaporation separator tends to thin out? Precautions?
What is the material of your equipment?.........

Material: 304L; designed capacity: 130,000 tons per year; actual capacity: 180,000 tons per year. The originally designed traditional CO2 stripping method is now replaced by the two-evaporation addition and two-evaporation separation processes used in the traditional aqueous solution process.
Material 304L won’t work; using titanium gives better results. 316L corrodes very quickly.
The key issue is that it worked fine for 12 years, but now there are problems whose cause cannot be explained or identified.
What process? Has it been operating under overload conditions all the time, or only recently?
The CO2 level has remained unchanged.
