Amine Unite Material Selection 1

[ChihebG]

Experts,
We have to select the materials of an Amine Unit removing CO2 (Up to 80% removal) from the following gas:
Feed Gas composition:
H2O : 0.18 mol%
CO2 : 16.51 mol%
CO : 2.41 mol%
N2 : 0.30 mol%
H2 : 74.79 mol%
C1 : 5.81 mol%
Total: 100 mol%
Amine Used: Monoethanolamine

What the major damage problems that shall be taken into consideration in this unit regarding the gas composition?

Thank you in advance.

Start with API RP 571 and look up amine corrosion and amine stress corrosion cracking, then take it from there.
