Dear sea friends, what is used to absorb the acidic gas emitted from your workshops?
Thread Content
As the title suggests, brothers, please share your insights
Some are absorbed using water, while others are absorbed using liquid alkali
Acidic gases from different sources have varying compositions, which depends on the composition of the acidic gases and the treatment applied after absorption. Acidic gases primarily composed of hydrogen sulfide are generally treated using a sulfur recovery unit. As for acidic gases primarily composed of carbon dioxide, they can be purified into pure carbon dioxide to be used as a raw material for dry ice. Some acidic gases, such as nitrogen oxides, which form highly acidic *ao acids after oxidation in the air, can be decomposed into nitrogen through urea absorption.
It depends on the specific components of these exhaust gases; different components require different treatment methods
The acidic gas is absorbed by spraying it with a low-concentration aqueous solution of sodium hydroxide.
