Chemical Process Equipment: Selection and Design

James R. Couper et al.

Synopsis

A facility is only as efficient and profitable as the equipment that is in it: this highly influential book is a powerful resource for chemical, process, or plant engineers who need to select, design or configures plant successfully and profitably. It includes updated information on design methods for all standard equipment, with an emphasis on real-world process design and performance:

• •

  Copious examples of successful applications, with supporting schematics and data to illustrate the functioning and performance of equipment.

• •

  Provides equipment rating forms and manufacturers' data to support the design process.

• •

  New material includes updated equipment cost data, liquid-solid and solid systems, and the latest information on membrane separation technology.

New publications show application of latest GPC/SEC detection technology (available free on Viscotek web site)

Viscotek, a Malvern company, has published new application notes illustrating the extended capabilities of gel permeation chromatography/size exclusion chromatography (GPC/SEC) using the new photodiode array (PDA) detector for the TDAMax™ system. Now available on the Viscotek web site, these application notes illustrate how the new detection technology brings greater flexibility to multi-component characterization and analysis in fields from polymer science to biopharmaceuticals. The application notes describe “Conjugated polymer analysis by GPC-PDA” and “Polymer blend analysis by GPC-PDA,”, respectively. Both are freely downloadable at: www.viscotek.com/gpcpda.htm

The Viscotek TDAmax is a comprehensive GPC/SEC system with an integrated triple or tetra detector array. By capturing absorption spectra across the UV-vis wavelength range, the new PDA detector provides a fingerprint of each “time slice” of the sample as it elutes from the column. Measurement times are just 30-40 min, making the system highly productive.

UV detection is used routinely to identify protein and polymer species as they elute, and can differentiate between components when other detection methods cannot. However, a conventional system measures at a single wavelength. In contrast, the new PDA detector captures data across the range 190-500 nm, allowing users to select wavelengths of interest after the analysis has been carried out.

The PDA also has particular application in the field of smart material research, since unique electrical, thermal or photochromic properties often correlate directly with UV absorption characteristics. The information it gives can be used in both product and process development.

The UV cell of the PDA sits in the temperature-controlled zone of the TDAMax™, operating at up to 80°C. Viscotek's powerful OmniSEC™ software package allows data to be displayed as information-rich 3D images that simplify interpretation.

GPC, also known as SEC, is a chromatographic technique that employs specialized columns to separate natural and synthetic polymers, biopolymers, and nanoparticles on the basis of size. When GPC/SEC is coupled with advanced detectors a range of additional parameters can be determined, including intrinsic viscosity, molecular size, and long chain branching.

Malvern adds “10 ways to control rheology by changing particle properties” to INFORM series of white papers

“10 ways to control rheology by changing particle properties” is the latest addition to Malvern Instruments' INFORM series of white papers, which are designed to provide advice on material characterization issues. Freely downloadable from the Malvern web site, this new document guides the reader through some of the fundamental properties of dispersed systems and demonstrates how these affect its rheology. A variety of examples illustrate the effects on rheology of changing particle size, size distribution, shape and zeta potential, alone and in combination (www.malvern.com/control_rheology).

Many materials used today are disperse systems where one substance, often a particulate, is dispersed in another phase. Examples are common in areas as diverse as adhesives, agrochemicals, cement, ceramics, colloids, cosmetics and personal care formulations, food and drink, mining and mineral slurries, paints, inks and surface coatings, pharmaceuticals and polymer systems. The physical properties of the dispersed particles – average particle size, size distribution, zeta potential or charge on the particles, and particle shape – all influence bulk material properties such as rheology. Therefore, the rheology of a dispersed system can be controlled through the measurement and manipulation of key parameters.

ChemTec Publishing announces a new edition of Handbook of Fillers. Nano- and micro-fillers

This handbook (www.chemtec.org/proddetail.php?prod=978-1-895198-41-6) gives direct comparison of general purpose fillers (micron-size fillers) and nanofillers. Over 3,000 research papers, mostly published from 1994 to 2009 (over 1,500 new papers in this edition), technical data from over 160 filler and equipment manufacturing companies, and patent literature were reviewed for this comprehensive handbook.

The book is designed to be single source of information for an experienced practitioner as well as a reference text for students and those new to the fields where fillers are used. The previous edition, used by very large number of readers, does not contain essential developments of extensive research on fillers in the last ten years, especially related to nanofillers.

Fillers, in most applications, are no longer used as cost-saving additives but they add value to final products, and many products cannot be successfully designed without them. This reference book is a powerful tool for today's challenges, which can only be met by those equipped with extensive information.

The book provides the information on three groups of relevant topics: available fillers and their properties, their effect on filled materials, and their use in practical applications.

One-third of the book covers the grades of fillers available in the world market. Fillers are divided into 83 groups and their properties are analyzed to pinpoint properties, applications, and sources. The technical information is a synthesis of information on several thousand grades of fillers manufactured today. The morphology of fillers, in addition to the numerical and other data, is illustrated by 154 SEM TEM, AFM micrographs.

The second part of the handbook discusses the effects of filler incorporation. Ten chapters cover the mechanical properties of compounded materials, the effect of the filler on material rheology, the morphology of the filled system, the material durability, flammability and recycling, the structure of interphase, chemical interactions, interaction with and effect on other additives, fillers use in material combinations, and the analytical methods of testing fillers and filled materials.

The last part of the book is concerned with application of fillers on an industrial scale. Several chapters discuss filler transportation, storage, processing and equipment used for these purposes. Others deal with the quality control of fillers, formulation with fillers, different processing methods, groups of products, and health and safety issues. This part is designed to assist industrial engineers to evaluate advances in the processing technology. It is also invaluable for chemists who design formulations for industrial processes and students in chemical engineering who must learn how modern industry operates in practical applications. The handbook is invaluable for sales and marketing because it gives possibility of direct comparison of fillers and their potential use and contains all required information to position them in the marketplace.

To summarize, major features of this handbook are:

• •

  Comprehensive review of literature.

• •

  The most current information.

• •

  Information required by scientists, engineers, marketing, sales, and students given in one source.

• •

  All aspects of filler properties, effects, and application thoroughly reviewed.

• •

  Contains all available information to make decision on what can be done by traditional fillers and where nanotechnology excels.
