Dear community,
I am struggling on the web to find a code or a norm stating officially how to choose the type of ammonia storage tank in function of the capacity required.
I have found some good reports saying roughly the following ;
- < 500 t : cylindrical tank under pressure --> pressurized storage
- between 500 and 3000 t : spherical tank under pressure --> semi-refrigerated tanks
- > 3000 t : storage at atmospheric pressure at a temperature of -33°C --> fully refrigerated storage in large tanks
Is there an API or EN code saying the same?
From your experience, do you agree with the above?
Why couldn't we build a big pressurised sphere for a 5000 t storage?
Thank you for your help
