Description

CHEMOPLEX OX is a superior quality diethylhydroxylamine (DEHA) based oxygen scavenger developed for boiler water treatment and acts as a direct replacement for Hydrazine. CHEMOPLEX OX has volatile and alkaline properties, thus completely deterring the accumulation of dissolved solids or ammonia to the boiler system. The protection from oxygen corrosion is outstanding and controls ferrous and non-ferrous corrosion in feedwater, boilers, steam and condensate lines. Furthermore, CHEMOPLEX OX provides excellent feedwater and boiler system passivation on all inner surfaces.It is crucial that boilers should be protected from corrosion and especially pitting corrosion. CHEMOPLEX OX effectively removes the dissolved oxygen, by reacting with dissolved oxygen and form non-corrosive compounds.The necessary dosage to maintain the concentration within the specified control range is determined by daily testing of DEHA in the feedwater using the DEHA TEST KIT.

Application

Use CHEMOPLEX OX according to the treatment programme that CHEMO has suggested. CHEMOPLEX OX may be applied to any boiler up to 125 bar, without the health and safety hazards, and handling precautions that Hydrazine imposes. CHEMOPLEX OX can be used as a direct replacement for Hydrazine.

Use and dosing

The dosing point should be placed in the boiler feed line or in the boiler body, using an injector and a dosing pump, as for Hydrazine. The dosage must be continued and the reserve of DEHA in the condensate must be kept within 0,10 and 0,30 ppm. Dosage is respectively increased or decreased by 25%, when outside these limits. For system start-up, use 100 – 300 mls per day of CHEMOPLEX OX, or higher, if the system has been poorly passivated. Use DEHA TEST KIT to adjust treatment level. Always test sample from the same sampling point of condensate, cooled and tested immediately. Improper control of the DEHA concentration will not provide adequate protection of the boiler system and may lead to accumulation of ammonia in the condensate with possible corrosion of copper alloy tubes. Keep the feedwater temperature as close to 90°C, or higher if possible, to minimize dissolved oxygen concentration.
