The silica must be removed from the water used for steam stimulation or steam-drive recovery programs. It may be removed by precipitation using either hot-process water softening or cold lime-soda softening, but the hot softening method is by far the most efficient technique. Silica may also be removed during ion-exchange treatment of the water. The hydroxides of aluminum, magnesium, and iron are well known and effective in silica removal. Magnesium and iron are available as commercial additives. As the silica concentration becomes less, the order of difficulty of removing the remaining silica becomes increasingly greater. The pH and temperature of the water affect the silica removal. The cold-process treatment may not be satisfactory as a method to reduce silica unless very careful techniques are used.
