Available in PDF, EPUB and Kindle. Book excerpt: A general scale-up correlation is developed for the volumetric gas-liquid mass transfer coefficient (k[Subscript L]a) in stirred-tank reactors (STRs) for oxygen transport using results from the literature and the current study. Power data for the dispersion of air in water by a six-bladed Rushton impeller are obtained by measuring electrical power, and a gassed power correlation is proposed. A correlation for gas-liquid mass transfer based on the energy input criteria of the form k[Subscript L]a = C1(P[subscript g] / V)[Superscript alpha]U[Superscript Beta and subscript g] fit the data well, but, in general, is dependant on flow regime and the vessel size. The volumetric mass transfer coefficient (k[Subscript L]a) is correlated on the basis of the relative dispersion parameter (N/N[Subscript CD]) for similar impeller hydrodynamics and operating regimes. A stirred-tank reactor scale-up technique from bench-scale (T = 0.211 m and D/T = 0.35) to industrial-scale (up to T = 2.7 m) is proposed using a normalized hydrodynamic flow regime map and shown to be useful in understanding the range of operational conditions for the successful scale-up of stirred tank reactors. The experiments show that the scale-up model can be applied for a single and or multi-gas component mass transport to liquids if the STR is operated in the same hydrodynamic regime. A method for determining dissolved carbon monoxide concentrations from artificial syngas is developed and the volumetric gas-liquid mass transfer rates are determined. The gas-liquid scale-up model is used in carbon monoxide mass transfer scale-up for syngas fermentation in a STR. Carbon monoxide mass transfer rates obtained in this work are predicted from those of air correlated from literature. A STR scale-up model is extended to other reactor types such as air lift reactors and bubble columns in mixing applications, and the corresponding gas-liquid scale-up model is suggested.

This book was released on 2022-12-19 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of carbon dioxide in our changing climate is now hard to ignore, and many countries are making pledges to reduce or eliminate their carbon output. Chemical valorisation of carbon dioxide, as an alternative to sequestration, is likely to play an important part in reaching these targets, and as such is one of the fastest developing areas of green chemistry and chemical reaction engineering. Providing a comprehensive panorama of recent advances in the methods and technologies for chemical valorisation of carbon dioxide, this book is essential reading for anyone with an interest in sustainability and green chemistry. Both the technological improvements in traditional processes and new methods and concepts are discussed, including various (renewable) electricity-based methods, as well as novel catalytic, photocatalytic and biocatalytic approaches.
