This document, produced by EFMA, provides guidance and an optimum basis for the periodic inspection of fully refrigerated anhydrous liquid ammonia storage tanks, operated in Europe. The recommendations and guidelines provided are applicable to those tanks, which operate at or near atmospheric pressure and -33°C.
The guidance uses a risk based inspection approach requiring the evaluation of the probability and consequences of failure for each individual tank. The underlying intention is to maximise operational safety and reliability of these tanks.
This document is updated at regular intervals, for example in 2008. For the latest version please refer to the website of Fertilizers Europe
