Wire mesh demister in the alkali solution tank

This post was last edited by sunjl1981 on 2013-1-6 at 22:06. I would like to ask everyone what material the wire mesh foam removers in the caustic solution tank (D270) used in operation are made of Is 310S useful? How effective is it? Is there any corrosion? ， ， -
Screen foam eliminators generally do not use 310S. 310S is primarily resistant to high temperatures; if corrosion resistance is required, 316L can be chosen. Materials such as Incoloy825 or Incoloy600!
There’s no need to use 310S; 304, 304L, or 316 will all work. Many decisions regarding costs need to be made based on the actual circumstances! !
The wire mesh demister on the caustic liquor circulation tank in the caustic soda PVC project is made of 310S
Since the material of the tank used for holding alkaline solutions is mostly 16MnR/N6, the internal components should also be made of N6, primarily to address corrosion issues.
There are essentially two reasons for the damage to wire mesh demisters: 1. Corrosion and erosion cause the wire mesh to fall off； 2. The strength of the scaffold is too low, and excessive condensate leads to gravitational failure of the mesh.
310S has good high-temperature resistance, and its cost-performance ratio in terms of corrosion resistance is excellent...
Alkali foam removers generally require 316L material; details can be discussed
Screen defoamers are often made of Monel alloy. . .
Determined based on alkali concentration and temperature; choose from 310S, 316L, or N6
