Improved handling of a complex process using the automation of continuous and batch sub-processes (ore digestion, hydrolysis, gel washing, chemical treatments, etc).

Large-scale technological process control according to the S88.01 standard, including:

• basic control
• advanced control solutions
• continuous procedural control
• batch-recipe control
• coordination control

Consistent use of the lifecycle concept in control systems’ design, the development and employment of advanced control algorithms, innovative recipe notation making possible the handling of simultaneous phases.

Increased capacity, higher yield of the raw materials (savings of approximately €400.000 per year), possible savings related to environmental taxes (due to a decreased quantity of waste gypsum) of approximately 180m tolars per year, improved quality of most of the sub-processes, some of the sub-processes can be controlled only by means of a computer.
