Book excerpt: Dynamic simulation of bioreactors is a challenge for both the industrial and academic worlds. Beyond the large number of physical and biological phenomena to be considered and the wide range of scales involved, the central difficulty lies in the need to account for the dynamic behavior of suspended microorganisms. In the case of chemical reactors, knowledge of the thermodynamic equilibrium laws at the interfaces makes it possible to produce macroscopic models by integrating local laws. Microorganisms, on the other hand, have the ability to modulate the rate of substrate assimilation. Moreover, the nature of the biochemical transformations results from a compromise between the needs of the cell and the available resources. This book revisits the modeling of bioreactors using a multi-scale approach. It addresses issues related to mixing, phase-to-phase transfers and the adaptation of microorganisms to variations in concentration, and explores the use of population balances for the simulation of bioreactors. By adopting a multidisciplinary perspective that draws on process engineering, fluid mechanics and microbiology, this book sheds new light on the particularity of bioprocesses in relation to physical and chemical phenomena. - Presents a multiphase description of bioreactor modeling - Includes a combination of concepts issued from different scientific fields to address a practical issue - Provides a detailed description of the population balance concept as applied to biological systems - Covers a set of illustrative examples of the interaction between hydrodynamics and biological response

Available in PDF, EPUB and Kindle. Book excerpt: Bioprocess engineering has played a key role in biotechnology, contributing towards bringing the exciting new discoveries of molecular and cellular biology into the applied sphere, and in maintaining established processes, some centuries-old, efficient and essential for today's industry. Novel developments and new application areas of biotechnology, along with increasing constraints in costs, product quality, regulatory and environmental considerations, have placed the biochemical engineer at the forefront of new challenges. This second volume of Advances in Bioprocess Engineering reflects precisely the multidisciplinary nature of the field, where new and traditional areas of application are nurtured by a better understanding of fundamental phenomena and by the utilization of novel techniques and methodologies. The chapters in this book were written by the invited speakers to the 2nd International Symposium on Bioprocess Engineering, Mazatlan, Mexico, September 1997.
Download or read book Effects of Configurations of External Loop Airlift Contactor on Hydrodynamics and Gas liquid Mass Transfer written by and published by . This book was released on 2007 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various configurations of external loop airlift contactor (ELALC) were examined for their hydrodynamic and mass transfer behavior using tap water. These behaviors was manipulated by changing the length of connection tubes (L[subscript c]), height of riser and downcmoer (L[subscript h]) and other configurations while keeping the ratio between downcomer and riser cross sectional area constant at 0.269. The results showed that the change of configuration could have effects on: gas holdup, liquid velocity, and gas-liquid mass transfer. Increasing L[subscript c] and L[subscript h] seemed to pose the same effect on the airlift performance. For instance, an increase in L[subscript c] from 20 to 40 cm, and Lp[subscript h] from 100 to 140 cm, could increase liquid velocity at 11.3 and 7.2%, decreased overall gas holdup at 8.6 and 3.3% and decreased the overall volumetric mass transfer coefficient at 8.2 and 5.6%, respectively. The effect of configurations on ELALC was investigated. ELALCs with inclined connection tubes and with close downcomer were compared with regular ELALC in terms of hydrodynamic and gas-liquid mass transfer behaviors. The two configurations presented large agglomerate of gas bubbles on the top connection tubes which resulted in more gas holdups and less downcomer liquid velocity when compared with regular ELALC. The mathematical model was developed based on the mass conservation principals to predict the gas-liquid mass transfer in the ELALC. Basically ELALC was represented by a series of reactors, i.e. the riser, downcomer, top and bottom connection tubes were represented by the dispersion model, and the two gas separators represented by the stirred tank model. The simulation results were found to be reasonably accurate for all experimental conditions employed in this work.

Download or read book Theoretical Chemical Engineering written by Christo Boyadjiev and published by Springer Science & Business Media. This book was released on 2010-10-20 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of theory in science was formulated very brilliantly by Max Planck: Experimenters are the striking force of science. The experiment is a question which science puts to nature. The measurement is the registration of nature’s answer. But before the question is put to nature,it must be formulated. Before the measurement result is used,itmust be explained, i.e., the answer must be understood correctly. These two problems are obligations of the theoreticians. Chemical engineering is an experimental science, but theory permits us to formulate correct experimental conditions and to understand correctly the exp- imental results. The theoretical methods of chemical engineering for modeling and simulation of industrial processes are surveyed in this book. Theoretical chemical engineering solves the problems that spring up from the necessity for a quantitative description of the processes in the chemical industry. They are quite different at the different stages of the quantitative description, i.e., a wide circle of theoretical methods are required for their solutions. Modeling and simulation are a united approach to obtain a quantitative description of the processes and systems in chemical engineering and chemical technology, which is necessary to clarify the process mechanism or for optimal process design, process control, and plant renovation. Modeling is the creation of the mathematical model, i.e., construction of the mathematical description (on the basis of the process mechanism), calculation of the model parameters (using experimental data), and statistical analysis of the model adequacy.
