Question

Chlorine ions used in wet scrubber technology tends to build up inside the scrubber and cause corrosion. Suggest a possible method to remove the large amounts of soluble chloride ions by producing a solid.

Answer 1

The main source of corrosion is due to build up of HCl.

To remove this ions with a solid intermediate, ammonia gas can be used to produce the white crystals of ammonium chloride

NH₃+ HCl → NH₄Cl
