Caustic wet scrubbers use an alkaline water-based solution to capture contaminants from waste gas. Different caustic solutions are used depending on the specific contaminant. Scrubbers are designed to ensure effective contaminant removal while efficiently controlling the chemistry conditions.
Caustic scrubbers are a necessary yet potentially costly treatment process in refineries and ethylene plants, used to ensure a high-quality end product.
For optimal removal of gases, it may be necessary to add high amounts of caustic, often however, poor control by utilising pH measurement rather than an online caustic analyser leads to over-dosing of caustic into the scrubber.
The Galvanic Accuseries is a proven online caustic analyser designed for use in industrial applications such as refineries.
