Gaskets
Gaskets
(OP)
I don't have much experience with gaskets and was hoping to get a second opinion from people here.
We have a pressure vessel with a rectangular flange (10"x30" apprx) and operating conditions of 100psi and 800F continous service. The gas used is going to be diesel exhaust (after catalytic converter and filters) We prefer to not use graphite based gaskets.
Any suggetsions or opinions on what gaskets would be best with the lowest price will be helpful.

Leaving out graphite, they should have a few composition materials usable at your temperature. I doubt anybody will sell asbestos anymore.
They can also perhaps consider the joint design when recommending a gasket. Narrow ring, full face?
How tight a joint are you looking for?
Many factors involved...

If your media is oxidizing you should go with a fibrous ceramic material.
RE: Gaskets
If you only need one gasket, and if your mating flanges are stiff and flat, I'd recommend making one by wire EDM of annealed copper sheet. There are lots of aftermarket automotive gasket makers that can do this for you.
If you flanges are not flat and/or stiff enough to seal with soft solid copper sheet, then ask for copper sandwich material. Depending upon how complex your flange shape is, you might be able to even get a sandwich material gasket made without tooling charges.
Either material will take your temperatures and pressures.
Good luck.
