Preparing a Brine Sludge Dissolving System for Maintenance

Preparing a Brine Sludge Dissolving System for Maintenance [Pg.79]

A major chemical plant dissolved inorganic slurry solids in a series of three fiberglass vessels. Most employees considered this section of the plant as one of the nonhazardous areas of this chemical complex. This area handled a relatively cool sodium chloride (table salt) water stream that was saturated with insoluble salts such as calcium carbonate and magnesium carbonate. The slurry contained about 30-percent calcium carbonate. Insoluble carbonates are treated with hydrochloric acid in two agitated vessels to allow a reaction to liberate carbon dioxide and form a soluble salt. The reaction is a simple one  [Pg.79]
