Hydrogen production acidic water stripping tower
Thread Content
What are the main components of acidic water? What is the principle of a stripping tower? What are the parameters of the purified water after stripping? Thank you for your help!
Acidic water mainly contains carbon dioxide (carbonic acid); the principle is the same as that of a deaerator, where steam is used to remove the gases dissolved in the water. You can refer to Henry’s law and Dalton’s law for more details. At that time, we didn’t set any requirements regarding the parameters of the water after extraction; it would still need to pass through a deaerator or be discharged into the sewer
The second floor is the correct answer. Here, the purified water after stripping goes through an oxygen removal tank before being used for steam generation. However, there is a problem at present: the steam produced in this way is not very good quality as it is corrosive, which means that replacement of the water is necessary quite frequently.
Mainly, the pH value is generally above 8; otherwise, corrosion is severe, along with considerations regarding chloride ions and conductivity
