low grade diasporic bauxite in the jajarm mine with an a/s (al2o3/sio2) ratio of 2.3 is not usable in the bayer process at jajarm alumina complex. due to the severe interlocking effect between the diaspore and aluminosilicate minerals (chamosite and kaolinite) and iron-containing minerals in a microcrystal matrix, the thermo-chemical treatment, which is independent from micro-mineralogy, was ch...

some of the most destructive accidents of 1980s and 90s which occurred in process industries were domino accidents. although domino accidents are among the most destructive industrial accidents, there are not much pioneering works done on quantification of them. the analytical formulation of the domino accidents is usually complex and need a deep knowledge of probability rules. even if the case...

Chemical process models are highly structured. Information on how the hierarchical components are connected helps to solve the model efficiently. Our ultimate goal is to develop structure-driven optimization methods for solving nonlinear programming problems (NLP). The structural information retrieved from the JModelica environment will play an important role in the development of our novel opt...

The 10th International Chemical and Biological Engineering Conference CHEMPOR 2008, was held in Braga, Portugal, from the 4th to the 6th of September, 2008.
