ABSTRACT:
The methods for decreasing scale formation in processes for the production of soda ash from trona or nahcolite ores are provided. Diphosphonic acid materials such as 1-hydroxy-ethylidene diphosphonic acid, 1-hydroxy-propylidene-1,-diphosphonic acid, 1-hydroxy-butylidene-1,-diphosphonic acid and 1-hydroxy-pentylidene-1,-diphosphonic acid have been found to diminish significantly the formation of magnesium scale in such processes.
