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.
