Sodium Sulfite - Catalyzed

Product #19700

Sodium Sulfite - Catalyzed (Na2SO3) is used as an oxygen scavenger in water based mud systems. It is soluble in water and catalyzed using a cobaltous compound. It may also be used as an anti-oxidant to prevent polymer degradation.

As an oxygen scavenger it is added continually until the residual sulfite (SO3) concentration in the mud filtrate reaches or exceeds 300 mg/L. Thereafter this residual is maintained with daily treatments in the order of 20.0-60.0 kg depending on the severity of the dissolved oxygen content in the drilling mud.
