Caretreat 4 Condensate

Caretreat 4 Condensate is an oxygen scavenger based on neutralized organic acids and a blend of volatile/neutralizing amines. It is normally used in conjunction with Caretreat 3 Boiler as part of the water treatment program. It removes oxygen efficiently in open feed systems and gives effective corrosion inhibition of boiler/exhaust gas economizer system surfaces by converting Fe₂0₃ (rust) to an organic iron compound. It also protects copper based metals. The amines pass over with the steam and have the dual function of elevating the pH of the steam/condensate and putting a protective micro film on the system's pipe work. Acidic condensate is the result of carbonic acid (H₂C0₃) being formed as CO₂ is released in the steam. The use of Caretreat 4 Condensate prevents corrosion by carbonic acid on live systems. Its filming properties also reduce corrosion on shut down lines, when moisture and oxygen are present.

• Environmentally safe, non-toxic product.
• Unique single product for corrosion control throughout the condensate system.
• Simple and accurate testing.
• Effective under all operating conditions.
• Protects boiler surfaces by forming an iron tannate film.

Caretreat 4 Condensate can be used in any type low and medium pressure boiler system. Caretreat 4 Condensate can be used in the following make-up water types: evaporated water, reversed osmosis water or demineralized water.

Caretreat 4 Condensate is dosed at a rate which maintains a pH of 9.0 to 10.0 in the condensate returns. Oxygen entrainment largely depends on Hotwell temperatures and if these are maintained at above 80 ˚C the condensate pH range of pH 9.0 to 9.5 is adequate. If Hotwell temperature control is irregular and averages less than 80 ˚C, tighter control is necessary and condensate returns should be kept in the range pH 9.5 to 10.0. It is not necessary to carry out oxygen or product residual tests.

Caretreat 4 Condensate is initially dosed at 0,2 ltr/m³ boiler water. Systems showing signs of corrosion should be dosed at up to 0,7 ltr/m³ boiler water for the first few days in order to passivate all metal surfaces.

After initial dose, the dosage depends on the quantity of steam production. A minimum of 15 ml/ton steam produced, should be dosed to maintain correct treatment levels in conjunction with regular top and bottom blown down and a correct condensate pH.

Caretreat 4 Condensate must be dosed continuously in conjunction with Caretreat 3 Boiler in a metering pump/tank unit, discharging directly into the feed system and/or the exhaust gas economizer circulating pump discharge. It must NEVER be slug dosed to a running system via a Hotwell or by-pass feeder. Marine Care supplies a complete range of dosing systems, from manual operated systems, to custom built computer operated high tech systems, for every application.
