Project Description

Potash Hot extraction stabilizing

Instability in “Hot Extraction” operation cause (among other things):

  • Instability in all Tanks Levels and hence reduction of production rate.
  • Bottle Necks: production means are not equally loaded which causes production losses even with no mechanical failures.

With the expected new Drying Furnace and new Sivanite Filters situation is expected to worsen.

Checking all parts of the process enabled us to improve the control performance and as a result to that – the stability both in feed rates and in tanks level.
