"Absorption & Stripping" by P. Chattopadhyay
Asian Books Pvt. | 2007 | ISBN: 8184120338 9788184120332 | 875 pages | PDF | 41 MB

This one banks heavily on industry & focuses its major concern on the industrial application of absorption and stripping
inasmuch as all unit operations must find their ultimate application in industries. It gives a detail survey of Tower Internals, DeSign of Absorbers & Strippers, Typical Industrial Absorbers & Strippers, Revamping of Absorbers & Strippers, Cost Estimation of Absorption Towers.

The book will come in good stead to the students of Chemical Engineering and Applied Chemistry as well as Process Engineers and DeSigners of CPls and PCls.

The first two chapters provide the necessary fundamentals and theoretical development of absorbers & strippers. Adequate numerical examples have been dished out to enable the reader to get a good grip of the topics.
DeSign of all gas-liquid contacting columns begins with the hydraulics of operation. So is this one. Hydraulics of all the three basic tray-columns as well as of packed towers have been explained to the minutest details. Discussed also are the factors & parameters that influence the hydraulics of packed towers. This is followed by basic concepts of design of Tray Towers and Packed Towers. Adequate numerical examples have been plugged in. Two chapters (CH-4, CH-5) deal exclusively with design.

Packings come almost inevitably with Absorption & Stripping. So little wonder why they'll occupy a special position in this book. So the author has devoted one whole chapter (CH-6) on packing.
Equally important are tower internals without which the packing's functions are seriously impaired. Each & every such tower internals has been discussed in comprehensive detail (CH-7).

Finally, the last three chapters on absorption & stripping of industrial importance, revamping of absorbers & strippers & cost estimation of absorption towers are a pleasant excursion to the domain of large commercial absorbers & strippers. Design consideration, design guidelines & operation of important industrial absorption have been discussed at length.
