Use of diethylaminoethanol, morpholine, and cyclohexylamine for condensate return line corrosion prevention
This technical note provides a description of and direction for use of three chemicals: diethylaminoethanol (DEAE), morpholine, and cyclohexylamine. These chemicals are used in Army boiler plants to prevent internal corrosion of condensate return lines. This technical note applies to all facilities engineering elements responsible for the operation and maintenance of steam-generating-boiler systems. Replacement costs for underground steam/condensate systems are high. There is also a high cost associated with reduced efficiency while systems are corroding. The use of neutralizing amines, notably DEAE, morpholine, and cyclohexylamine, play a large role in the curtailment of condensate corrosion. This note describes the use and properties of these amines and provides information to simplify the choosing of an appropriate neutralizing amine to give the most-economical and effective results in different systems.
