The condensate return line treatments below react quickly to neutralize condensed steam carbonic acid with amines to neutralize the return line and buffer the pH level. When it comes to condensate water treatments for boilers, you won’t find more advanced specialty chemicals. There are many types of condensate treatments, but the most common are amines. Amines fall into two major categories: filming and volatile. The volatile amines are completely soluble and therefore, can technically be fed in the boiler. They are considered volatile because they flash off and are carried with the steam into the rest of the system. These types of volatile amines are often referred to as short range, medium range and long range neutralizing amines, because of the distance they are able to travel “down pipe.” Neutralizing amines are alkaline and, therefore, neutralize the acids that can form in the condensate by raising the pH. Neutralizing amines control corrosion in condensate applications by diminishing the effects of carbon dioxide and other acid forming compounds.
