    we are designing a 36" finger type slug catcher (8 finger each 65m) to carry hydrocarbone with 3.22% H2S, 3.65% CO2, 0.5% WATER and 43000 MG per water-Litre CHLORIDE and settele time of hydrocarbone is long and may corrode the pipe. Design press. is 1760psi (900# RTJ) & design temp. is -29,90 C. we have chosen A106 Gr. B for pipe and F6A class1 for valve trim acc. to NACE/ISO 15156. is this material selection the best solution or are there better alternatives? thank you.
