Abstract
A method and product for use in controlling the deposition of silica-containing scales and their adhesion to the walls of piping and other plant components. The product is an amine to which is attached at least a pair of terminal groups. Each group is selected from the family of compounds consisting of furfuryl and a saturated or unsaturated hydrocarbon radical substituted with one or more members selected from hydroxy and carboxy, or a hydrohalide thereof. The method includes injecting the additive into saline brine or brackish water containing silica which may tend to precipitate as a scale.
