The special scale inhibitor for wet-process phosphoric acid is a dedicated additive to solve the scaling problem in the production of wet-process phosphoric acid. It is synthesized from special integrated surfactants, solubilizers, synergists, and other additives through a specific process. It effectively prevents or slows down the formation of easily scaling substances in wet-process phosphoric acid production, loosens deposits, and reduces the adhesion of scale. With a certain amount of addition, it can significantly extend the continuous normal production cycle without adversely affecting the wet-process phosphoric acid production process and its subsequent processes. It is a very effective additive for wet-process phosphoric acid production.
Key words:
Dilute phosphoric acid contains certain impurity salts. During the concentration production process, due to the evaporation of water, the impurity salts in the dilute phosphoric acid are also concentrated. When their concentration exceeds their solubility, they will precipitate out and deposit as scale on the heaters, evaporators, acid transfer pumps, and pipelines of the concentrated phosphoric acid production unit, severely affecting the continuous normal operation of production and causing significant economic losses to the enterprise.
In the production process of ammonium phosphate, the sedimentation and separation of phosphoric acid sludge is a very important link, as it directly affects the quality of subsequent products and technical economic indicators. Therefore, it is crucial to study how to accelerate the sedimentation and separation of acid sludge. Traditional natural sedimentation is not only slow and incomplete, but also requires investment in a series of sedimentation tanks. Therefore, introducing purifying agents in the phosphoric acid purification process to significantly accelerate the sedimentation speed of acid sludge is of great significance.
In the production process of phosphate fertilizers, the quality of phosphoric acid has a significant impact on subsequent production. With the continuous decline in the quality of phosphate rock, relying solely on existing facilities and methods can no longer meet the demand for high-quality phosphoric acid for downstream production. To improve the quality of phosphoric acid, the use and selection of phosphoric acid settling agents become extremely important. Phosphoric acid settling agents can quickly promote the sedimentation of suspended impurities in phosphoric acid at lower dosages, and can also react to some extent with impurity ions such as iron, magnesium, and aluminum in phosphoric acid to form insoluble precipitates, thereby improving the quality of phosphoric acid.
Q875D is composed of polymer surfactants and fatty acid esters. It is resistant to high temperatures and strong acids, with significant defoaming and foam suppression effects. It is widely used in the extraction of phosphoric acid from phosphate rock using sulfuric acid, hydrochloric acid, and nitric acid, as well as in the desulfurization of feed-grade phosphates and in the defoaming process during titanium dioxide production. It requires a small amount, acts quickly, and is environmentally friendly.
Phosphoric acid filtration production modifier is a specialized additive designed to solve the scaling problem in the production of wet-process phosphoric acid. It is synthesized from special integrated surfactants, solubilizers, enhancers, scale inhibitors, high-efficiency dispersants, and other additives through a specific process. It effectively prevents the formation of easily scaling substances in wet-process phosphoric acid production, slows down deposition, loosens, and reduces the adhesion of scale. With a certain amount of addition, it can significantly extend the continuous normal production cycle without adversely affecting the wet-process phosphoric acid filtration production process and its subsequent processes. It is a very effective additive for wet-process phosphoric acid production.
The Q637 phosphoric acid extraction crystallization modifier developed by our company is produced using high-quality raw materials through advanced processes and technologies. The addition of the Q637 phosphoric acid extraction crystallization modifier in the wet phosphoric acid production can effectively improve the crystallization behavior of gypsum, facilitating the formation of coarse and uniform crystals, increasing gypsum crystallization, and benefiting the filtration and washing of gypsum. At the same time, the Q637 phosphoric acid extraction crystallization modifier also has the effects of accelerating the extraction reaction, increasing the growth rate of gypsum crystals, and enhancing the production capacity of the equipment.
