A process for treating water to reduce silica based compound scaling in steam generation equipment is provided, including the step of subjecting water to a cation removal process to reduce the di- and trivalent cation concentration within the water to, most preferably, less than about 20 ppb prior to introducing the water into the steam generation equipment. This process eliminates the need for a lime softening stage and savings in capital and operating costs are realized.
L'invention concerne un procédé de traitement d'eau visant à réduire la formation de tartre contenant des composés à base de silice dans un appareil de génération de vapeur. Ce procédé comprend une étape consistant à soumettre l'eau à un processus d'élimination de cations de manière à réduire la concentration en cations divalents et trivalents dans l'eau à une concentration idéalement inférieure à environ 20 ppb avant d'introduire l'eau dans l'appareil de génération de vapeur. Le procédé de l'invention permet de ne pas mettre en oeuvre d'étape d'adoucissement à la chaux et de réaliser des économies en terme de coûts financiers et de fonctionnement.
