The ion exchange method in potassium carbonate manufacturing

In addition to a large number of tubes for glass and color TV sets, potassium carbonate is an important carbonate variety. The application of potassium carbonate has expanded into various industries such as pharmaceuticals, chemical dyes, inks and welding electrodes.

The ion exchange method is an important process for the production of potassium carbonate. It is used by most potassium carbonate manufacturers. The ion exchange method is further improved, and the potassium carbonate manufacturers have improved the ion exchange method.

Potassium carbonate manufacturers recycle ammonia ions. According to the principle of chemical equilibrium, the more the amount of ammonia ions in the ion exchange process relative to the amount of potassium ions, the higher the utilization rate of potassium ions. However, in consideration of economic and operational factors in actual production, the ratio of potassium ion and ammonia ion selected by the potassium carbonate manufacturer needs to be controlled within a certain amount, which is about 1:1.29, so there is no large amount of ammonia ion in the exchange liquid. Being used, it also causes waste of raw materials. Potassium carbonate manufacturers need to recycle these ammonia ions, which can achieve good economic benefits.

Similarly, the concentration of potassium bicarbonate in the solution should be controlled. The potassium carbonate manufacturer can produce more than 13% of the exchange liquid, which can reduce the steam consumption in the evaporation process and fully carry out the ammonium carbonate solution. The utilization has reduced the cost of raw materials and the emission of pollutants in ammonium chloride wastewater, and has a good comprehensive benefit.

Potassium carbonate manufacturers have improved the steam section to remove impurities such as iron ions, which has increased the yield of color TV grade potassium carbonate products to 70%. The potassium carbonate manufacturer improved the evaporation mode and used three-effect evaporation to enhance the carbonization effect.
