Abstract
A process for reducing calcium, magnesium and aluminum salt scale build-up in continuous flow or plug flow tube reactors in which a fluid waste undergoes a chemical reaction under heat and pressure to form more environmentally desirable compounds. The process includes the injection of a precipitating reagent into the influent path of a fluid waste stream in a tube reactor to preferentially precipitate calcium, magnesium and aluminum ions which are then carried through and out of the reaction apparatus in a non-scale forming suspension.
