Multi component analysis

Continuous information about the concentration of each main component is required for optimal control of process to ensure a high level of quality, efficiency and safety. This is true for continuous as well as for batch processes.

Often process analyzers are used. These analyzers use various classical analytical laboratory methods in sophisticated and complex designed apparatus. These devices allow the concentration determination of single components concentrations in a multi component blend.

These instruments have several limitations:

  • high maintenance effort
  • continuous consumption of chemicals
  • non-continuous operation

A good alternative solution is the SensoTech combination method. The LiquiSonic system processes the signals of physical properties in a multi component blend. This methods works without expensive sample devices and is maintenance free and very durable. 
The
 signals of the different sensors will be processed within a multidimensional model calculating the actual concentration of each component.

The LiquiSonic® analyzers combine the following measuring methods:

  • sonic velocity and density
  • sonic velocity and conductivity
  • sonic velocity and refractive index

With the application of multi component analyzers the customer can reduce budgets dramatically, because of the lower chemical costs and reduced maintenance efforts.

For the control of such neutralization processes pH-sensors are often used. The performance of these sensors is less effective in higher process temperatures, or in the case of lye spill over. In such cases, the use of sonic velocity sensors together with a second physical value is recommended to achieve maximum plant safety together with minimized consumption of leach.
