Study of Aqueous Ammonium Chloride Corrosion in Refinery Crude Distillation Unit Overhead Conditions
...Abstract One of the main corrosion threats to the crude distillation unit overhead piping is related to the presence of HCl and NH3. It is generally recognized that three forms of corrosion associated with the presence of HCl and NH3 can potentially exist in the overhead...

... and it starts primarily from the presence of hydrogen chloride (HCl) vapor present from the hydrolysis of salts in the condensate feed. The most common source of HCl is the hydrolysis of calcium chloride and magnesium chloride salt at temperatures exceeding 120°C (240°F) though the HCl may also come from...
