Question 4

What valve material should I use for anhydrous ammonia service?

Accepted Answer

For liquid ammonia (−33°C to ambient), use A350 LF2 carbon steel body with PTFE seats and SS316 trim — no copper, brass, or zinc alloys. For synthesis loop gas (H₂/N₂ at 150–300 bar), use A217 WC9 (Cr-Mo alloy) gate valves verified against the API 941 Nelson curves for hydrogen attack. For urea melt (185°C, 150 bar), SS316L is mandatory — carbamate in the loop attacks carbon steel rapidly.

Question 5

Do ammonia plant valves need NACE MR0103 certification?

Accepted Answer

NACE MR0103 (Materials Resistant to Sulfphide Stress Cracking in Corrosive Petroleum Refining Environments) applies when H₂S is present — common in ammonia plants using natural gas feedstock via desulphurisation. Key requirement: body and trim hardness ≤ HRC 22 (Rockwell C). If your feedstock is H₂S-free coal or electrolysis, NACE may not be mandatory, but most licensors (Haldor Topsoe, KBR, Casale) specify it as a precaution.
