Beschreibung
This book provides support to engineers as well as graduate students in their daily design work within the industry or for the development of new plants. It investigates the key issues relating to the fluid dynamic design of packed columns used in rectification, absorption and stripping (desorption) under vacuum, normal pressure and up to 100 bar and liquid-liquid-extraction, which are relevant in waste air and wastewater technology. The author presents a standardised model, which is valid for any type of packing and can be used to calculate the gas velocity at flooding point as well as the liquid hold-up and the pressure drop throughout the entire operating range for random packings, stacked packings elements, tube columns and structured packings with different flow channel angles. The book also contains packing parameter data for approx. 200 random and structured packings. In addition to outlining the fundamental principles of fluid dynamics, it presents numerous examples of practical application.
The?rstGermanedition of thebook“Fluiddynamicsofpackedcolumns with modern random and structured packings for gas/liquid systems” was published in 1991. It sold out within a few years. Added to this were numerous enquiries, in particular within the industry, prompting me to publish a second, extended edition. A packed column remains the core element of any diffusional separation process. This underlines the need for basic design principles for packed columns, which enhance the design process by making it more accurate and reliable. The SBD (suspended bed of droplets) model introduced in the ?rst German edition of the book was well received by the experts and is now used by a large number of com- nies in the industry, as it offers improved reliability in the ?uid dynamic design of packed columns. For the purpose of facilitating the design process, the SBD model was in- grated into the simulation programme ChemCAD. The software programme FDPAK, which is available for Windows, has certainly contributed to the widespread use of the SBD model. The programme is very user-friendly and the calculation results are p- sented in tabular as well as graphic form, showing ?ood load, pressure drop and hold-up diagrams in the entire operating range.
Describes the basic principles design of columns equipped with modern lattice packings and structured packed beds, as generally used in industry Is based on more than 10,000 experimental pressure drop data, in excess of 1,200 flooding point data and approx. 1,100 liquid hold-up data for nearly 200 different types of packings Provides support to experts as well as graduate students in their daily work Includes supplementary material: sn.pub/extras
