The function of the Department of Chemical and Biological Engineering has been to prepare students for the study and application of chemistry in industry. This focus has included preparation for employment in various industries as well as the development, design, and operation of equipment and processes within industry.Through the CBE Department, Iowa State University is nationally recognized for its initiatives in bioinformatics, biomaterials, bioproducts, metabolic/tissue engineering, multiphase computational fluid dynamics, advanced polymeric materials and nanostructured materials.
History
The Department of Chemical Engineering was founded in 1913 under the Department of Physics and Illuminating Engineering. From 1915 to 1931 it was jointly administered by the Divisions of Industrial Science and Engineering, and from 1931 onward it has been under the Division/College of Engineering. In 1928 it merged with Mining Engineering, and from 1973–1979 it merged with Nuclear Engineering. It became Chemical and Biological Engineering in 2005.

Abstract
Chemical enhanced oil recovery (EOR) methods are alternatives to increase oil production in mature reservoirs. However, the presence of EOR chemicals in the produced water may impact the separation of gas-water systems in oil platforms. The present work aims to evaluate the impact of polymers, surfactants, inorganic salts, and their interactions on gas holdup in a 32.1-cm-diameter semi-batch bubble column over a range of superficial gas velocities ranging from 0 to 19 cm/s. It has been confirmed through physical-chemical analysis that synthetic produced water containing salts, polymers and organic surfactants is non-Newtonian with low surface tension. Results have shown that both salt and surfactants increase gas holdup regardless of superficial gas velocity, while the effect of polymers depends on superficial gas velocity. This work also innovates by showing how interactions between EOR chemicals and salinity affect transition gas holdup and superficial gas velocity between different flow regimes. Overall results shed some light on how the chemical composition of EOR effluents affect gas holdup and flow regime as a function of a wide range of superficial gas velocities and therefore contributes to the development of gas-liquid systems.
