Hydrochloric acid corrosion is a general and localized corrosion and is very aggressive to most common materials of construction. Damage in refineries is often associated with dew point corrosion in which vapors containing _______ and hydrogen chloride condense from the overhead stream of a distillation, fractionation, or stripping tower.
Hydrochloric acid corrosion in refineries is often associated with dew point corrosion where vapors containing water (H₂O) and hydrogen chloride condense from the overhead stream of a distillation, fractionation, or stripping tower. The presence of water in the vapors is essential for the condensation process, which leads to the corrosive effects of hydrochloric acid.
Hydrochloric acid (aqueous HCl) causes both general and localized corrosion and is very aggressive to most common materials of construction across a wide range of concentrations. Damage in refineries is most often associated with dew point corrosion in which vapors containing water and hydrogen chloride condense from the overhead stream of a distillation, fractionation, or stripping tower.
