Course content

the course is given every second year, next autumn 2025. The course gives an introduction to how surface and colloid chemical phenomena influence industrial processes. The most important topics that are covered are flow assurance, separation and processing of oil and water. Phenomena that are described in the course include mechanisms for asphaltene and wax precipitation, formation and stabilization of gas hydrates, separation of oil/water/gas, stabilization and destabilization of water-in-crude oil and crude oil-in-water emulsions, electro-coalescence and functionality of various oil field chemicals (inhibitors, demulsifiers, defoamers, wetting agents, etc.). Other processes that are covered are pulp and paper technology, where surface chemistry for wood and cellulose fibers as well as dissolved and colloidal components in the process fluids are described, and the significance of surfactants and polymers in industrial applications such as food, detergents, paints and cosmetics. Here, an introduction to interactions between surfactants and polymers in aqueous solutions will be given; both with respect to intermolecular interactions and phase behavior/separation, as well as adsorption of surfactants and polymers onto solid surfaces. An introduction to the main principles of modern instrumentation for characterization of surface and colloid chemical phenomena will also be given.
