Selection of suitable Material for sour service at low temperatures

[Salmet]

Dear Members, please suggest if some body has experienced the case for selection of suitable material with working temperature at minus 90 degree C for the transportation of a mixture of around 4 % H2S and 3.4 % CO2 gas. Thanks in advance

 

These are hazardous materials in extreme conditions.
Crowd-sourcing is not an appropriate design approach, and the framing of your question suggests you have little familiarity with standard industry materials of construction, which are just one aspect of equipment design.
Please retain a qualified design firm with experience in your application.
