Discussion on material issues in synthetic isobaric ammonia recovery towers
Thread Content
Hello, dear colleagues. We are currently installing a synthetic ammonia plant with an annual production capacity of 100,000 tons. We plan to use a pressure equalization recovery tower with a DN1200 diameter to recover the gas released during synthesis as well as the gas from storage tanks, in order to produce ammonia water. Our original equipment was made of carbon steel, but the design team now requires that all components be made of 304 material. I wonder if this is really necessary Is it necessary to use 304 material for the heat exchange tubes with internal cooling?
Gaga, actually Q235A will do; there’s no need to use stainless steel!
In my humble opinion, for ammonia, stainless steel should be used, as ammonia is corrosive
