Metal plating is a basic environmental protection technology that neutralizes acidic, basic or toxic gases that are prohibited to be released into the atmosphere in the chemical, mining and energy production sectors by transferring them from the gas phase to the liquid phase. Over 99% gas retention efficiency is achieved by simultaneous operation of absorption, chemical neutralization and particle retention mechanisms.
The main purpose of scrubber systems is to maximize the contact surface area between the dirty gas stream and the washing liquid (absorbent). The transition of gases such as SO₂, HCl, NH₃, Cl₂ to the liquid phase is governed by Henry's Law and diffusion principles.
