Material selection for Boiling concentrated Sulfuric acid?
(OP)
I am trying to develope a process that involves boiling sulfuric acid, 91% Sulfuric acid at 260°C. I am curious if anyone else has had any success in finding a material of construction capable of taking these harsh conditions. the material would be used to construct the reactor vessel. So far I have found that a glass-lined reactor is possible, however, gasketing material (normally PTFE/graphite) may degrade releasing HF and corroding the glass.
Any metals worth while???

I know that alloy 20 and G30 will not handle this service.

Going that way trades corrosion problems for mechanical design (sealing preload control and dimensional accuracy) ones. SiC-coated steel pipe is another potential route.

Known that the seawater in itself is not filtered, this poses an erosion potential for small bore pipe.
Any takers, please???
