When the mineral content of the water used for thermal recovery processing has considerable hardness, it is usually desirable to consider lime-soda softening. Lime and soda, acting in combination, will precipitate out the calcium and magnesium salts, or the hardness of the water (lime = calcium hydroxide; soda = sodium carbonate). The amount of lime and soda used to soften water is determined by the hardness, which is removed either by precipitation or by the conversion of some of the salts into soluble forms which will not precipitate out, in the thermal recovery program. Lime and soda are used in the treatment of water in thermal recovery methods, in order to prevent the formation of scale and deposits in the steam generators. The chemical reactions taking place in this water treatment are described.
