Book Description
This comprehensive review, prepared by 24 experts, many of whom are pioneers of the subject, brings together in one place over 40 years of research in this unique publication. This book will assist R & D specialists, research chemists, chemical engineers or process managers harnessing periodic operations to improve their process plant performance. Periodic Operation of Reactors covers process fundamentals, research equipment and methods and provides "the state of the art" for the periodic operation of many industrially important catalytic reactions. Emphasis is on experimental results, modeling and simulation. Combined reaction and separation are dealt with, including simulated moving bed chromatographic, pressure and temperature swing and circulating bed reactors. Thus, Periodic Operation of Reactors offers readers a single comprehensive source for the broad and diverse new subject. This exciting new publication is a "must have" for any professional working in chemical process research and development. - A comprehensive reference on the fundamentals, development and applications of periodic operation - Contributors and editors include the pioneers of the subject as well as the leading researchers in the field - Covers both fundamentals and the state of the art for each operation scenario, and brings all types of periodic operation together in a single volume - Discussion is focused on experimental results rather than theoretical ones; provides a rich source of experimental data, plus process models - Accompanying website with modelling data

Book Description
Gas-liquid-solid (catalysts) reactive systems encountered in trickle bed reactors are common in chemical engineering related cocurrent gas and liquid downflow systems. Among these processes relying on trickle beds, hydrodynamics of foaming systems are less prominently explored subject despite the formation of foaming is very often in the petroleum industries. This study's aim was to demonstrate experimentally the effects of liquid and gas flow velocities, and liquid surface tension for key phenomenon like regime transition change, two-phase pressure drop, dynamic liquid hold-up and liquid axial dispersion. More than 240 experimental points for the trickle flow (GCF) and foaming pulsing flow (PF/FPF) regime were obtained for present study, revealed significant evaluations for sustainable process design especially for industrial applications.

Dynamically Structured Flow in Pulsed Fluidised Beds
Author: Kaiqiao WuPublisher: Springer Nature
ISBN: 303068752X
Category : Science
Languages : en
Pages : 172
Book Description
This book analyses the use of a pulsed gas flow to structure bubbling gas-solid fluidised beds and to induce a special fluidisation state, called "dynamically structured flow", as a promising approach to process intensification. It explores the properties of bubbles rising in staggered periodic arrays without direct interaction, assessing their size, separation, and velocity, and explains how a highly uniform, scalable flow offers tight control over the system hydrodynamics. These features are desirable, as they not only bypass engineering challenges occurring in traditional operations, such as maldistribution and non-uniform contact, but also allow to decouple conflicting design objectives, such as mixing and gas-solid contact. The thesis also presents computational simulations which reveal the periodic transitions of the particulate phase between fluid-like and solid-like behaviour. This book will be of interest to researchers, engineers, and graduate students alike, particularly those working in industrial drying, combustion, and chemical production.
