AIChE Equipment Testing Procedure – Centrifugal Compressors. A Guide to Performance Evaluation and Site Testing

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.

Performance Evaluation is a hands-on text for practitioners, researchers, educators, and students in how to use scientifically-based evaluations that are both rigorous and flexible. Author Ingrid Guerra-L?pez, an internationally-known evaluation expert, introduces the foundations of evaluation and presents the most applicable models for the performance improvement field. Her book offers a wide variety of tools and techniques that have proven successful and is organized to illustrate evaluation in the context of continual performance improvement.

This issue focuses on connections between performance management and evaluation, a contentious topic at the moment. It does so by placing evaluation and monitoring under the overarching concept of performance management, and then by investigating five complementarities between performance monitoring and measurement on the one hand, and evaluation on the other. These complementarities are: Sequential Informational Organizational Methodical Hierarchical. Several case studies discuss the uses and complementarities of evaluation and performance management in contexts including national and local governments and the work of government, philanthropic foundations, and a direct-service nonprofit agency. These cases illustrate the advantages and pitfalls in utilizing evaluative approaches within the context of performance management. This is the 137th volume of the Jossey-Bass quarterly report series New Directions for Evaluation, an official publication of the American Evaluation Association.
