water disposal system material selection
(OP)
We are designing a waste water disposal system. High Cl (32,000ppm), High TDS and operating temperature (100 degree C). What exchanger materials would you suggest? Waste water is on the tubeside.

We need more info.
The ferric chloride solution used in G48 C and D is 33,000ppm Cl and a pH of <0.5.
There are very few (very expensive) metals that will work at 100C in this.
Now if the pH were near neutral then superaustenitic, superferritic and superduplex grades might all become candidates.
If the pH is high then a superferritic would be the clear favorite.

The pH is 12. How about 2205 DSS. Is it OK in this service?

you can consider copper alloys..

You might be able to use a super-duplex also (Zeron 100 or 2507).
