Process Intensification in Multiphase Reactors

Introduction Applications of multiphase technology are prevalent in petroleum refining, synthesis gas conversion to fuels and chemicals, bulk commodity chemicals, specialty chemicals, conversion of undesired by-products to recyclable products, manufacture of polymers, biotechnology and pollution abatement. In these processes the reactor performance is crucial: it determines the number and size ...

Process intensification in mechanical pulping

Process intensification is a term used in the chemical process industry for major improvements in the process design leading to radical changes in process complexity, equipment size and efficiency. We suggest that a similar approach is applied in the pulp and paper industry. We have focused on the production of mechanical pulp, but a similar approach can be applied to other areas within the pul...

Electrocoagulation: an electrochemical process for water clarification

Electrocoagulation is a group of various procedures used for removing contaminants from water by electrochemically dissolving aluminum or iron. The contaminants of the solution may be incorporated in the in situ forming metal hydroxide flocs, which can be filtered as a precipitate or skimmed as a float. The main features of the procedure are highlighted on the example of cleaning of an oily was...

Process Fragmentation: An Ontological Perspective

Process fragmentation provides the basis for re-usability and process improvement. Various re-searchers have already introduced different definitions for what constitutes a reasonable process fragment, and have offered algorithmic support for identifying such fragments. As we will show in this paper, some of these definitions suffer from ambiguity or imprecision. Therefore, the objectives of th...
