Boiler oxygen scavengers are of various types depending upon the type and capacity of the boiler. These can be based on catalyzed sodium sulfite, catalyzed potassium sulfite, catalyzed sodium bisulfite, catalyzed hydrazine hydrate, carbohydrazide etc.

The catalyst present in the product enables quick and instant removal of oxygen from the feed water. The products remove oxygen and also passivate the system metal to prevent corrosion.

Chemtex’s Oxygen Scavenger surpasses the performance of other oxygen scavengers such as Elimin-ox, Nalco 1700, Nalco 1710, Nalco 1720, Nalco 1721, Nalco 1722, Maxtreat 3100, Maxtreat 3100L, Maxtreat 3200, Maxtreat 3220S, Indion 166, etc.

Carbohydrazide Based Boiler Oxygen Scavenger

Chemtex’s Carbohydrazide or Carbohydrazid CAS No.497-18-7 Based Boiler Oxygen Scavengers are very effective and superior. Carbohydrazide based oxygen scavenger helps to remove unwanted dissolved oxygen from the boiler water, in order to prevent oxidation corrosion and formation of carbonic acids. It is an organic corrosion inhibitor used for scavenging oxygen and passivating metal surfaces.

It can be used in boilers where steam is used in the manufacture of paper and paperboard that might be employed for food contact purposes. Note however that it cannot be used to treat boilers where steam produced will contact food or food products.
