In the pulp and paper industry, the alkaline sulphate process, which is where fibrous material is separated from lignin, is important. These chemicals need to be recycled, due to environmental and economic reasons, so it is vital that this process runs smoothly.
To get it wrong can cause complications and cost time and money.
SensoTech’s LiquiSonic analysers monitor the process
What actually happens?
Lignin, an organic material, and others like it, are removed through a process that concentrates and burns the black liquor. What is produced through this recovery process is a smelt with high salt content as well as energy, providing the base material for green liquor. The sodium carbonate in green liquor, through the causticising with lime, is converted to sodium hydroxide, which is reused in white liquor for the next pulping process.
The LiquiSonic analysers monitor each step inline, in an optimal manner, which leads to productivity increases as well as optimised quality control.
What are the applications?
• Green liquor concentration is monitored in real-time.
• In different processes, phase detection and separation occurs.
• Black liquor evaporation monitoring.
• Control of incoming goods.
• Control of recycled white liquor.
What are the advantages?
• Steam washing is not necessary as it is layer free.
• Laboratory costs are reduced.
• In causticising, there is ideal dosage of lime.
• Maintenance free processes even with high temperatures (200°C) and liquors with high coating.
• No dismounting and remounting required for cleaning or maintenance.
• Accurate inline concentration measurement for black, white and green liquor.
• Enhanced operational safety.
For the high demands that are placed on sensor technology in the pulp and paper industry, SensoTech sensors have been built to withstand the harsh working environment and can be adapted to existing process conditions.

Analytical Instrumentation & Environmental Monitoring
Cooling towers rely on evaporation to remove heat, but this process also concentrates dissolved solids in the system. Left unmanaged, this buildup can lead to scaling, corrosion and fouling, reducing efficiency and increasing maintenance costs.
