What kind of lining should I choose

[YST89]

I am working on a project with following water:

Sodium (Na+) mg/l 25,000.0
Carbonate (CO32-) mg/l 12000.0
Sulphate (SO42-) mg/l 1000.0
Chloride (Cl-) mg/l 22000.0
Total Dissolved Solids 70000.0
TSS mg/l 1800.0
pH 12-13
Silica (SiO2) mg/l 5000.0
Insoluble oil (oil & grease) mg/l 100 - 150
Total Organic Carbon: normal mg/l 4000.0
Temperature ºC 90 - 100

Any body have idea what kind of material or lining will have resistance to this water?

Any comment is appreciate

There are a few options you may want to consider. Because of the operating temperature range of 90 to 100°C you are limited to a coating that can withstand high immersion temperature you can choose a stoved phenolic ( this will require the component to be brought to a autoclave to bake-on the coating)this coating biggest limitation is than it is difficult to field repair and has limited abrasion resistance. On the other hand you can also choose an epoxy base coating (sprayed-on or hand applied). Usually epoxy coatings can be found with ceramic fillers that will provide adequate abrasion resistance but you must be careful as not all epoxy coatings are created equal when it comes to high temp immersion resistance. Make sure whomever you choose that they can back-up their high temp claims with real traceable information and not what is just printed in their data sheets.

Good luck
