Acid-base neutralization tower

Acid-base neutralization towers are mainly based on acid-base neutralization reactions or physicochemical processes such as adsorption and absorption. When dealing with gas deacidification, the tower is filled with a high-efficiency packing layer or tower plate that provides sufficient contact area between the gas and liquid phases. When the gas passes through the packing layer from bottom to top, the alkaline absorbing liquid (e.g. ammonia, sodium hydroxide solution, etc.) sprayed from the top of the tower reacts with the acidic components in the gas and converts them into salts or acid salts, thus realizing the purification of the gas.
