AIChE manual updates and consolidates procedures for testing performance of distillation columns From classic distillation operations to air stripping to other separations processes, selecting the correct column for appropriate efficient, safe, and environmentally-sound operations can be an important step. The newest updated volume in AIChE’s long-running Equipment Testing Procedures series, Trayed and Packed Columns: A Guide to Performance Evaluation, Third Edition provides chemical engineers, plant managers, and other professionals with helpful advice to assess and measure performance of a variety of distillation columns, including those that utilize bubble cap, sieve, valve trays, or packing material. The new book combines and updates into one user-friendly volume the best available field knowledge from previous publications on both types of distillation columns. Designed not as a single set of compulsory steps, but as a compilation of techniques, it will allow the user to select the procedure that best applies to its operating parameters. The testing steps presented can be used to assess reliable performance data on mass transfer efficiency, capacity, energy consumption, and pressure drop—information essential to effective troubleshooting of performance problems, identifying capacity bottlenecks, determining operating ranges, and a number of other routine maintenance and optimization processes. Opening with an extensive definition section, organized by topical area, the book then goes on to address: Selection of instrumentation and identification of elements to be measured Pre-test planning procedures Strategies for data collection and evaluation, including sampling procedures Pre-test, in-test, and post-test considerations (equipment, safety, process, environmental) Computation and interpretation of results, including individual breakdowns for trayed and packed columns in terms of hydraulic and efficiency performance Test troubleshooting analysis in twelve key areas The book concludes with appendices for relevant symbols and nomenclature, plus sample caculations generated from performance tests. With its engineer-tested procedures and thorough explanations, Trayed and Packed Columns: A Guide to Performance Evaluation, Third Edition is an essential text for anyone engaged in implementing new technology in equipment design, identifying process problems, and optimizing equipment performance.

Dow Chemical developed the Chemical Exposure Index to help its engineers design and operate safer facilities. This seminal guide to rating the relative acute health hazard potential of a chemical release to workers and the neighboring community is available to the chemical process community. The index uses a methodology for estimating airborne quantity released, which allows for more sophisticated process analyses. Special Details: Softcover. The Dow Chemical Exposure Index and the Dow Fire and Explosion Index Hazard Classification Guide and the are designed to complement each other, helping engineers evaluate the total hazard potential of new installations These guides are invaluable resources for process design engineers, plant managers, and others involved in the safe design and operation of chemical plants. Don't take your plant's safety analysis only halfway--Purchase both books and take $10 off the combined list price.
This testing procedure provides methods of conducting and interpreting field tests on centrifugal pumps with actual pumped fluids. Contents include definitions and descriptions of terms; test planning; instrumentation and measurement methods; test procedure; computation of results; and interpretation of results. The volume also contains appendix materials including nomenclature; sample test results; sample calculation (dual units); related calculations; and references.
This popular safety best-seller is designed to help the user quantify the expected damage of potential fire and explosion incidents in realistic terms, identify the equipment likely to contribute to the creation or escalation of an incident, and communicate the fire and explosion risk potential to management. Based on Dow's Fire and Explosion Risk Analysis Program, the index provides a step-by-step, objective evaluation of the actual fire and explosion, as well as reactivity potential of process equipment and its contents.
Spray Dryers: A Guide to Performance Evaluation, Second Edition discusses the reasons for spray drying. These reasons are usually to produce a product with certain desired properties or with better efficiency than other methods. The book discusses how to plan in light of these objectives and gives guidance on the variables affecting product properties and dryer performance, to decide which variables to evaluate. Technical spray dryer installations are briefly described. Checklists are given to aid in planning measurements and listing steps needed for a test.
Violent Extremism: A Nordic Outlook illuminates the global issue of violent extremism, with a particular focus on Sweden and the Nordic countries. This concise volume leverages empirical research to uncover the mechanisms and dynamics driving violent extremism, setting itself apart in a field often criticized for a lack of data-driven analysis. The contributors employ unique Nordic data to offer insights on violent extremism, examining its organization, the evolution of extremist groups, online presence, and societal impact. Aimed at fostering a deeper understanding of the complexities of violent extremism, the contributions draw on several social science perspectives to enhance prevention and intervention strategies. This approach not only enriches our grasp of extremist organizations and individual paths in to or out of extremism but informs effective counter measures. Essential reading for policymakers, researchers, and security professionals, this volume offers practical, empirical insights on tackling a pressing challenge in societies around the globe.
Positive Displacement Pumps is a current reference guide for positive displacement pumps for both traditional and state-of-the-art testing methods, and serves as a bridge between textbooks and manufacturer's literature by providing equipment testing practices based on technical know-how, practical experience, and academic theory. With its simple, practical focus, this book not only is a resource guide to any engineer's task, but also adds important information to the overall literature of pump fundamentals and operating reliability: Written for field users, and terminology concisely defined. A mentoring guide highlighting areas for troubleshooting problem-solving when performance criteria are not met. Produced with industry consensus and gone through the same rigorous technical review process as other ETPC procedures.
This procedure offers complete methodologies for sampling and measuring particle streams and summarizes methods of particle size analysis. It also lists operating variables to be considered and measured. Although the procedure is intended specifically for particle classification equipment, many of the items are also relevant to particle collection devices.
This work includes case histories of loss prevention incidents - from the hidden hazard exposure of plastics used in construction, to electrostatic ignitions in everyday operations - that emphasise how such incidents could be prevented in the future.
Prevention, preparedness, response and recovery--the key components of emergency planning--form the major sections of this work. The book first describes PSM (Process Safety Management) as the key to prevention, then goes on to consider the main features of a preparedness program, including recognizing credible incidents, planning practical strategy to deal with these incidents, selecting necessary physical support systems and equipment, and developing a complete emergency response plan. The Response section presents the functions implemented during an actual emergency and concludes with a section on managing cleanup and restoration of operations. The many tables and figures include Sample Incident Command System Plans for both large and small organizations, OSHA and EPA regulations affecting planning, sample Fire Emergency Action Levels, HAZMAT Responder Levels, and OSHA Emergency Training Requirements.
