Diethylhydroxylamine

Diethylhydroxylamine Oxygen Scavenger

Diethylhydroxylamine (DEHA) is an organic compound [(C2H5)2NOH] is a colorless liquid mainly used as an oxygen scavenger in water treatment. It is very important to remove oxygen from the boiler feed water as oxygen can cause serious issues in the steam producing plant by fostering corrosion in the total boiler system. The reasons due to which DEHA find its popularity as an oxygen scavenger is because of its ability to passivate steel and its low toxicity. As an Oxygen Scavenger, DEHA works efficiently removing oxygen at a rapid rate under normal boiler conditions. Its volatility is similar to amine and has the ability to provide protection to overall condensate system as well as boiler system.

DEHA is used in boiler water treatment applications, as an oxygen scavenger for medium and high pressure boilers. DEHA also functions as a free radical scavenger in polymerization, it is a short stopper in the production of styrene butadiene rubber.

Key Features and Benefits

Completely organic nature
Volatile product, does not add to TDS of blowdown water
Metal passivator and rust converter
Eﬀective condensate line treatment and pH booster
Non-toxic and safer than hydrazine and carbohydrazide based chemicals
Compatible with other boiler treatment chemicals

Compatible with other boiler treatment chemicals
Returns to the feed line with the condensate return so passivates total system
High rate of reaction with oxygen compared with other oxygen scavengers
Offers vapour liquid distribuon ratio of 1.3 and thus distributes all along the condensate circuit
