Show all headers | View raw

This book represents an extensive volume (in the order of 800 pages) that covers most aspects of particle technology including size reduction as well as size enlargement and in some cases with a lot of detail. This volume is restyled and includes some changes with respect to the previous version, affecting chapters and sections (eg crystallisation, gas cleaning) leaving scope for other topics (membrane separation, product design).

The previous volume available in this series emphasises separation methods, and this recent version also touches on the topic of solid separation methods. However, the new version does not focus as much on final purification methods, which is unfortunate as this is an area that is gaining increasing attention because of the need to upgrade product purity. As an example, current lithium sources for lithium batteries require high purity grade lithium (>99.95%).


He co-wrote a textbook on chemical engineering with John Coulson (published in 1954), which developed into an established series of six texts now known as Coulson & Richardson's Chemical Engineering. (He and Coulson were largely responsible for the contents of the first two volumes: they were editors but not prime authors for the rest of the series of six volumes.) He continued editing the series after the death of Coulson in 1990.


John M. Coulson and John F. Richardson co-wrote a textbook on chemical engineering first published in 1954, which developed into an established series of six text books known as Coulson & Richardson's Chemical Engineering book series. They were largely responsible for the contents of the first two volumes while they were editors for the rest of the series of six volumes. Richardson continued editing the series after the death of Coulson in 1990. In order to keep the popular book series updated after the death of Richardson in 2011, Elsevier Limited has selected several eminent educators to edit/update contents of the book series. Dr. Ajay K Ray has been selected to serve as the Volume Editor for the sixth edition of Coulson and Richardson Chemical Engineering Volume 2B: Separation Processes. Dr. Ray is responsible for modifications, additions and editing of 13 chapters of the volume 2B of the book series.


The conventional production process of a liquid biofertilizer consists of three well-defined stages or steps (figure 1). In the first step, known as Bacteria Propagation, the bacteria are cultivated in flasks of different volume which contains a specific culture media, until the desired cell concentration is achieved. Once this expected cell concentration is reached, the liquid culture containing the living cells (pre-inoculum) are transferred (inoculated) to the larger volume flasks containing the culture media. The inoculum volumes commonly used are: 250 mL, 500 mL, 3 L and 5 L. When in the 5 L inoculum flask a cell concentration of 109 cells per mL is achieved at the following conditions: 32 C of temperature, 250 rpm of agitation and pH of 6.0, the entire volume of the final propagation flask (5 L) is inoculated to the seed fermenter, thus indicating that the second process step (Bacteria Cultivation) is just starting. At the same time that the cells are being propagated in the culture flasks, the culture media to be used both at seed and industrial fermenters are being prepared, sterilized and cooled within the same fermenters, prior to inoculation with propagated cells. The 5 L final propagation inoculum is transferred to 20 L of a specific, previously sterilized culture media contained inside of the seed fermenter, thus starting the seed fermentation step. This step usually lasts for 24 - 55 hours, until a cell population load higher than 1 09 cells/mL is obtained. The seed fermentation is carried out at 302 C, 400 rpm, pH of 6.0 and 1.0 v.v.m of aeration rate. Once finished the seed fermentation step, the cell suspension contained within the seed fermenter is inoculated to the industrial fermenter, which already contains about 225 L of a previously sterilized culture media. The industrial fermentation process proceeds at 302 C, 600 rpm, pH of 6.2 and 1.5 v.v.m of aeration rate, and has a duration time of about 3 - 4 days, which is the standard period to obtain a cell concentration higher than 109 cells/mL at the industrial fermentation broth. At this point the third and last process step (Bacteria Recovery/Formulation/Packing) starts. The industrial fermentation broth is then harvested in a cylindrical, vertical tank equipped with agitation and cooling. The harvested broth is cooled to 10 C prior to centrifugation, and then is pumped to a clarifying, desludging-type, disk-stack centrifuge for cells (biomass) separation and recovery. The supernatant obtained is sent to the wastewaters treatment section, while the biomass suspension is recovered in another vessel (formulation tank), cooled to 15 C, and then formulated by adding some formulation substances under agitation conditions. The addition of the formulation substances [sucrose, glycerol, NaH2PO4 and (NH4) 2PO4] will extend the shelf-life of the liquid inoculant, protect the cell suspension against thermal or pH variations and shocks, as well as improve applicability and performance of the formulated liquid in the field. As said before, the resulting formulation liquid is agitated within the formulation vessel, under 300 rpm for 6 hours approximately, using a paddle-type agitator. Once finished the agitation time, this mixed liquid will be gradually fed to an automatic filling machine, to be ultimately poured into 1.5 L plastic bottles. The filled bottles should be finally stored at 1 0 C.


The plant will has a production capacity of 44 tons of liquid biofertilizer per year, while the volume of liquid biofertilizer to be obtained per batch will be about 590 - 594 L (average of 592 L), The duration time of each production batch will be 109 hours/batch (5 days/ batch, approximately), the total required amount of labor needed to operate the biofertilizer production plant, taking into account management staff, supervisors, operators, maintenance crew, office employees, etc., will be of 29 persons. The total amount of production batches required per year to fulfill the production capacity will be 78 batches/year. The plant will be shut down for about 30 days per year in order to carry out usual maintenance operations, equipment adjustment and repairs, thus the annual operating of the plant will be around 7900 hours/year.






Throughout his career, his major thrust was on the wellbeing of the discipline of chemical engineering. In the early years of his teaching duties at Imperial College, he and his colleague John Coulson recognized the lack of satisfactory textbooks available in the field of chemical engineering. They set about rectifying the situation, and this is how the now well-known Coulson-Richardson series of books on chemical engineering was born. The fact that this series of books (six volumes) is as relevant today as it was at the time of their first appearance is a testimony to the foresight of John Coulson and Jack Richardson.


The basic philosophy and the objectives of this edition remain the same as articulated so very well by the previous authors of the fifth edition, except for the fact that it has been split into two subvolumes, 2A and 2B. In essence, this volume, 2A, continues to concentrate on the fundamentals of particulate processing operations, as applied to wide-ranging industrial settings. In particular, consideration is given to the characterisation of particles, both at the individual level as well as in bulk, in terms of their size, shape, texture, packing characteristics in the context of storage, and flow in bins and hoppers, etc. Similarly, the processes used to effect size reduction and enlargement of particles and the segregation and mixing phenomena in dry solids are also introduced in this volume. The next set of topics includes the all-too-familiar operations of the flow and heat transfer in packed and fluidised beds and in the settling of concentrated slurries and suspensions. These ideas, in turn, are applied to the classification of solids based on their size and/or density differences using the gravity or centrifugal flow fields. The entire volume has been reviewed while keeping in mind the feedback received from the readers and reviewers. Wherever needed, both contents and presentation have been improved by reorganising the existing material for easier understanding, or new material has been added to provide updated and more reliable information. Apart from the general revision, the specific changes made in this edition are summarized below:


Details of the current restructuring of this Chemical Engineering Series, coinciding with the publication of the Fourth Edition of Volumes 1 and 2 and to be followed by new editions of the other volumes, have been set out in the Preface to the Fourth Edition of Volume 1. The revision involves the inclusion in Volume 1 of material on non-Newtonian flow (previously in Volume 3) and the transference from Volume 2 to Volume 1 of Pneumatic and Hydraulic Conveying and Liquid Mixing. In addition, Volume 6, written by Mr. R.K. Sinnott, which first appeared in 1983, nearly 30 years after the first volume, acquires some of the design-orientated material from Volume 2, particularly that related to the hydraulics of packed and plate columns.


In this volume, there is an account of the basic theory underlying the various unit operations, and typical items of equipment are described. The equipment items are the essential components of a complete chemical plant, and the way in which such a plant is designed is the subject of Volume 6 of the series which has just appeared. The new volume includes material on flowsheeting, heat and material balances, piping, mechanical construction, and costing. It completes the Series and forms an introduction to the very broad subject of Chemical Engineering Design.
