Material selection for hydrogen-handling reactors in environments with hydrogen sulfide and chloride ions

For the pre-hydrogenation section of a refinery catalytic reforming unit, the operating medium consists of oil and gas + hydrogen + hydrogen sulfide (800 PPm) + chloride ions (70 PPm). The operating temperature is 350 degrees, and the operating pressure is 2.5 MPa. Under these operating conditions, what material should be used for the reactor? It is not clear whether the use of chromium-molybdenum steel (21/4Cr0.5Mo) + composite stainless steel (316+347) will be sufficient; in particular, the issue of chloride ions causing corrosion in the stainless steel composite material needs to be considered.
