Dissolved oxygen in water, even as little as 1 ppM, is still quite effective in producing corrosion and formation of deposits which will cause premature failure of the equipment. Certain chemicals are known as oxygen scavengers. There are many types of these compounds, but one that is quite extensively used is sodium sulfite in combination with a catalyst. The sodium sulfite may be added continuously to the water going into a steam generator or to water for a secondary recovery program. The sodium sulfite should be maintained at just a sufficient level to remove all of the oxygen, since any excess may be injurious. Sodium sulfite may react under high temperature and high pressure conditions to form acidic compounds, which is not desirable. Cobalt, as a cobaltous ion, is very effective as a catalyst; copper, as a cupric ion, is also quite effective. A chart shows the beneficial effects of cobalt and copper catalysts on the rate of reaction between oxygen and sodium sulfite. Under certain conditions, sodium sulfite will not only remove the oxygen present but will also remove other materials.
