Advanced phosphoric acid production technology
At present, our company has developed the most advanced phosphoric acid production technology in the world, completely different from the traditional production technology, the advantage is to save investment costs, reduce production costs, greatly improved the efficiency of the environment.
We offer 2 types of production technology
1. New Phosphoric Heat Treatment Process Heat process
Traditionally, it is necessary to produce P4 from rock phosphate by electric furnace, then P4 burns into P2O5 and absorbs water into phosphoric acid.
Our new heat process, we can directly produce P2O5 from the phosphate rock, and then absorb water into the phosphoric acid, this process shortens the process flow, and the reaction produces energy that can are integrated use, mainly energy-saving production.
2. Phosphoric acid wet
We use advanced membrane filtration, replacing conventional solvents, significantly reducing emissions.
This process is characterized by investment savings, low production costs, low energy consumption, the ability to produce fertilizers, and the purification of industrial phosphoric acid.
Our company's new process features phosphoric acid heat:
1. This process can directly produce 75% industrial phosphoric acid, which is applied to be used in all areas of traditional heating processes, such as powdered STPP detergents, chemical organic and inorganic fields.
2. Energy is the integration and optimization for the use, energy savings.
3. Slag can be used directly for cement production, with no problem releasing plaster.
This process can be applied to low grade rock, high silicon, high iron aluminum, magnesium and calcium phosphate that can be used directly, which can not be used for wet processes. It can be done for the phosphorus resources gradually drying up the trend.
5. Process flow is short, processing plant and investment workshop less than traditional heat process.
6. The productivity of phosphoric acid production is reduced largely, lower production costs and higher profits.
7. Compared with the traditional heat process, less investment, quickly return.
8. Integrated production costs are lower than the process of acid-phosphoric wet process.
9. With the next purification unit, with multi-level purification to food grade phosphoric acid, the electron-level phosphoric acid. Enrich the products, increase the value added products.
Wet processes according to Asia Chemical Characteristics In Following:
1. This process can directly generate 55% of highly concentrated phosphoric acid, according to customer requirements, it can concentrate more on 75%.
2. High-strength bearing hydrant gypsum can be sold, or build a production line of gypsum board or sheet.
Comparative process with traditional wet process, energy saving, phosphate consumption and gypsum sintering.
4. No waste plaster waste.
5. By-products in gypsum, can significantly reduce production costs.
