How to prevent equipment corrosion in desulfurization units?
Thread Content
Corrosion of desulfurization equipment during operation has always been a problem. Do you have any effective methods to prevent equipment corrosion?
Is it alkali-based desulfurization or ammonia-based desulfurization? We are now switching to alkali-based desulfurization; the corrosivity increases, so vanadium pentoxide is added along with the alkali.
The stainless steel material can be used in the key areas! Reduce the number of reductions!
Keep the pH value above 9; preferentially use Q235-B instead of Q235-A for the equipment materials
Magnesium hydroxide method should be used for desulfurization now; it is technologically advanced and causes less pollution, and it is employed by the vast majority of countries in Europe and America.
