A fast and accurate analysis of the liming process is an important step in juice purification in a sugar factory. The on-line process analysis enables continuous process monitoring of the beet juice, enabling immediate process regulation. The automated sampling process optimizes reliability.
The automatic value determination results in a higher analysis frequency and offers current information about the process control. It can rapidly detect variations of the pH-value. The on-line titration system allows the exact dosing of lime to improve clarification and to reduce overdosing. Determination of alkalinity can reduce the consumption of limestone and coke. The aim is to optimize process performance, avoid product losses, and control limit levels. To this end, Schmidt + Haensch instruments are designed to monitor characteristics of process streams.
- Combination of on-line analysis and automatic control systems
