The reaction medium inside will be sodium carbonate solution, with a concentration of around 30%, a temperature of approximately 260 degrees, and a pressure of about 2.5 MPa. There is also stirring involved, and the operation is batch-type. What kind of material would be suitable for use in this case?
I use 06cr19ni10 for both the containers for NaOH and KOH
Can’t carbon steel be used? Is your dosing sequence static or dynamic?
All the ingredients are added together, mainly to prevent alkali embrittlement.
To ensure stable and safe operation for about 5 to 8 years, which material would be suitable?
The quality requirements of the product also need to be taken into consideration; if the requirements are standard or low, materials such as carbon steel can be chosen, while for higher requirements, 304 or higher-grade materials should be selected.
