ProcessLab for paper & pulp: Analysis of white, green and black liquors |
|
|
|
|
|
The paper and pulp production is a well-established industrial process that has been adapted over time to fit today`s needs. Resource management has become vital in a constantly changing market. Quality and a high yield are here the key words to achieve a maximum price for the end product. Strong competition constantly forces production to optimize conditions.
In contrast to this are the input costs and the market price of the value-added chain. The gap between buying and selling is the profit, which needs to be optimized by effectively and quickly amortizing investments. |

Analysis of Bayer aluminate liquors using thermometric titration |
|
|
|
|
|
| Thermometric titrimetry is ideally suited for industrial process control analysis. The thermometric sensor requires virtually no maintenance and because endpoints are located from the second derivative of the titration solution temperature curve, no calibration is required. Moreover, titrations are typically fast, leading to high analytical productivity. An illustration of the utility of the technique is the high-precision automated analysis of total hydroxyl, carbonate and alumina values in sodium aluminate solutions in the refining of alumina by the “Bayer Process”. Pure sodium aluminate solutions are also produced for use in water purification, the manufacture of paper and of synthetic zeolites; the method described here is also suitable for these solutions. |
