Abstract

processo para produzir cristais de cianeto de sódio a presente invenção refere-se a um processo para produzir cristais de cianeto de sódio que compreende: (a) colocar em contato o cianeto de hidrogênio impuro e hidróxido de sódio em um reator com mistura por um tempo máximo de contato de cerca de 5 segundos; (b) alimentar a mistura resultante a um cristalizador de evaporação contínua para produzir uma pasta fluida de cristais de cianeto de sódio; (c) passar a pasta fluida de cristais de cianeto de sódio do cristalizador sobre uma superfície quente para precipitar sobre a superfície e remover carbonato de sódio, e passar a dita pasta fluida de volta no cristalizador; e (d) separar os cristais de cianeto de sódio da pasta fluida.
