Failure mode
Example :
leak of NH3

Ammonia arrives in gas form in the evapocondensor where it is condensed and turn into the liquid form that exits. Depending on the position of the leak, the consequences with regards to risks are not the same. If it occurs upstream: the loss of product takes place in vapour phase.If it occurs downstream: the product loss takes place in the liquid phase which comes from the evapocondensor but also from the drains, of the bottle high pressure...
