Project Description

Cristalizers Density Control stabilysing

In the process of Potash (KCl) production Carnallite [KMgCl3·6(H2O)] and water are fed into crystallizers. Instability in the Carnallite rate of feed requires the water to follow and maintain the proper ratio between these two streams.

Examining the system and instrumentation we found some mistakes in the control strategy implementation.

We redesigned the control strategy.

Number of readings outside the required values dropped dramatically.

Stage II of this project brought significant savings in water consumption and reduced the Potash lost considerably.
