In a chlorine dioxide (ClO2) generation plant,primary and secondary reactors are critical components of the process used to produce ClO2 efficiently and safely. Their design and function depend on the production method being used and the chemical precursors.
The Primary Reactor is the main reaction vessel where the generation of chlorine dioxide occurs. These are constructed from carbon steel (CS) in accordance with the Indian Standard for Unfired Pressure Vessels. All wetted parts are lined with double layers of chemically pure lead and are rigorously tested to ensure long service life.
The secondary reactor plays a crucial role in separating by-products like chlorine gas (Cl2), acid mist, and non-condensable, allowing chlorine dioxide to be collected in a more purified form & reducing the carryover of corrosive species into downstream systems. The MOC of the secondary reactor is PVC-FRP largely due to the extremely corrosive nature of ClO2 and its by-products.
