Challenges in hydrochloric acid Market

Corrosion Risks from Gaseous Chlorine Compounds

One of the challenges associated with the use of hydrochloric acid is the potential for corrosion caused by gaseous chlorine compounds. The presence of hydrochloric acid or molecular chlorine in the gaseous phase significantly accelerates the rate of steel corrosion. Waste incinerators, for example, can operate at high rates of around 1000 nm/h, leading to the destruction of the hematite layer and the erratic and porous behavior of the magnetite (Fe3O4) layer. While various chlorine compounds have the potential to cause gaseous corrosion of metals, hydrochloric acid and chlorine (Cl2) are the most common culprits. In boiler conditions, hydrochloric acid is dominant due to the water vapor present in flue gas.

Chlorine has the ability to penetrate oxide layers of protection before reacting with the metal surface to generate chlorides. It can diffuse across the oxide layer, particularly through gaps or pores in the scale layer. The oxygen potential at the scale-metal boundary is relatively low, as oxygen is consumed during the formation of oxides, resulting in a low partial pressure of oxygen. Corrosion by gaseous chlorine compounds manifests as a dark multilayer oxide coating that has weak adherence to the tube and measures between 0.1 and 0.3 mm in thickness. When removed, a thin, brownish film is often observed on the tube surface. Although the deposit layer is typically thin in evaporators, it can become thicker if superheater tubes experience this type of corrosion.
