Steam Boiler Chemicals - These include Oxygen Scavengers, Amines, Phosphates, Polymers, and Alkalinity Builders. Oxygen Scavengers - Most common type is 38%, pH < 4. Other solutions come blended with a cobalt catalyst and alkalinity contributors. These blends are usually 50% dilutions and come in 7 and 10 pH. Using these blends eliminates using

These oxygen scavengers are available as stand-alone products or compounded with scale & corrosion inhibitors and steam & condensate line corrosion inhibitors. Oxygen scavengers are critical to preventing dissolved oxygen from causing corrosion (called oxygen pitting) in boilers. Aries product line includes non-volatile, volatile, catalyzed

High Pressure Boilers For high-pressure boiler applications volatile or zero solids oxygen scavengers are required. These chemicals are usually used where a thermal deaerator is fitted and don't add to the TDS. Corroban 22 is based on DEHA (Diethyl hydroxylamine) and provides not only oxygen scavenging and protection for the boiler system but is also steam volatile so helps to inhibit

Boiler Oxygen Scavengers are used to remove dissolved oxygen from the boiler feed water and boilers. Dissolved oxygen in the boiler is very corrosive at higher temperatures and pressures. This may lead to localized pitting and premature boiler tube failure or excessive feedwater leaks.

Oxygen Scavengers: Corrosion is most commonly caused by dissolved gases (primarily oxygen and carbon dioxide), low pH, the attack of mechanically stressed areas, and under-deposit attack. To avoid the corrosion of vital (and costly) metal components throughout boiler systems, external treatment of the feedwater is performed in order to remove

Oxygen-related metallic corrosion is a significant issue in the operation and maintenance of industrial boiler systems and steam raising plant. To ensure that such boiler systems are well maintained and operate at optimum efficiency it is essential that the correct water conditions are maintained at all times.

Fresh water contains dissolved oxygen. Oxygen together with high temperature is highly corrosive for the carbon steel piping used in steam systems. To avoid corrosion the oxygen in the make-up water for saturated steam production should be removed by using some kind of scavenger chemicals and/or deaeration towers.

Steam boilers supply energy to the facility's operations. Due to the elevated temperatures and the concentration effect in steam systems, the quality of the feedwater supplied to the boiler is essential and must be effectively treated to protect the boiler from contaminants such as dissolved oxygen, dissolved carbon dioxide and mineral salts.
