The present disclosure is related to a low freezing temperature phosphoric acid composition. Phosphoric Acid (PA) has a typical concentration of 75, 80 and 85%. One of the drawbacks of phosphoric acid is that, as its concentration increases, its freezing temperature also increases. As a result, the main strength of acid used for various applications remains 75%wt which freezes at -18C; as it is easier to handle and store during cold season. A considerable amount of phosphoric acid is being transported and stored every year in large quantities, mainly at 75% or sometimes but more rarely, at 85%, requiring heating equipment to prevent solidification. |
