Assessing Bentonite In Papermaking
Assessing suitability of calcium bentonite for appliion ...
Bentonite is a clay mineral widely used in many industrial appliions. Bentonite is a major constituent of the drilling fluid used in oil well drilling operations. Some of the functions of drilling fluid include removal of drilled cuttings from the hole, cooling, and lubriion of the drill bit, and suspension of drilling cuttings when operations are stopped. There are two major forms of ...

The purpose of this paper is to present a method for assessing whether optimized process design and operations, based on simplified simulation models, can be carried towards real life. The proposed method relies on a more realistic, or if available, a set of more and more realistic simulation models being compared with the original model utilized in the optimization problem.

Paper Industry | Bentonite
Bentonite is crucial to paper making, where it is used in pitch control ( absorption of wood resins that tend to obstruct the machines), to improve the efficiency of the conversion of pulp into paper, and to improve the quality of the paper. Bentonite also offers useful deinking properties for paper recycling. In addition, acid activated ...
