DEAE (Diethylaminoethanol) / DEEA (Diethylethanolamine)

DEAE (Diethylaminoethanol) / DEEA (Diethylethanolamine)

DEAE (Diethylaminoethanol) / DEEA (Diethylethanolamine) – DEAE is a chemical product that has neutralizing and oxygen scavenging characteristics, and is used as a corrosion inhibitor for steam and condensate lines. 

As an alkanolamine, it maintains a constant alkalinity in boiler water and condensate, and it does not contribute solids to the boiler system. 

Neutralizing Amine

Neutralizing amines are a common steam line treatment that can be fed in a water treatment solution along with other treatment chemicals or it can be fed direct to the steam header. 

When feeding the amine to the feed water system, it should be fed downstream of the deaerating equipment. DEEA is utilized in the water treatment, gas treating, water-based and solvent-based coatings, and pharmaceutical industries, among others.

The neutralizing amine is volatilized and carried out with the steam in the condensate to react with carbon dioxide.

Key Features and Benefits

• Condensate line treatment

• Prevent of carbon dioxide corrosion

• Prevents formation of carbonic acid in boiler steam system

• Does not add to TDS of boiler water

• Completely volatile

• Prevents stress cracking corrosion

• Reduces blow down requirement

• Does not add TDS

• Returns to the feed line with the condensate return so raises the feed water pH

• Saves power

• Compatible with other treatment chemicals
