Zusatztext "...a work that deserves a place in every corporate library where on-stream analysis is important to the company's long-term economic health." (Control Magazine! March 15! 2002) Informationen zum Autor ROBERT E. SHERMAN is President of Petrolab Company located in Latham (Albany), New York. Sherman is recipient of The Instrumentation, Systems, and Automation Society's Molloy Award (1997) for Best Selling Publication (Analytical Instrumentation: Practical Guide for Instrumentation and Control) and the Fischer Environmental Award (2001) for his Continuous Emissions Monitor System (CEMS) work with Fluor/Duke. Klappentext "Sampling systems are one part chemistry, one part engineering (electrical, chemical, mechanical, civil, and maybe even software). No one person possesses all of the knowledge required. Bob (Sherman) comes as close as anyone." --John A. Crandall, V.P. Sales Americas, ABB Process Analytics This resource provides both novice and experienced technologist with the technical background necessary to choose sample conditioning system components that will allow the process analyzer system to function reliably with minimal maintenance. The conditioned process sample presented to the process analyzer should be of similar quality to the calibration material used to zero and span the analyzer. Filling a long-standing void in the process field, this book addresses the system concept of Process Analyzer Sample-Conditioning Technology in light of the critical importance of delivering a representative sample of the process stream to the process analyzer. Offering detailed descriptions of the equipment necessary to prepare process samples, and listings of two or more vendors (when available) for equipment reviewed, Process Analyzer Sample-Conditioning System Technology discusses: * The importance of a "truly representative sample" * Sample probes, transfer lines, coolers, and pumps * Sample transfer flow calculations for sizing of lines and system components * Particulate filters, gas-liquid and liquid-liquid separation devices * Sample pressure measurement and control * Enclosures and walk-in shelters, their electrical hazard ratings and climate control systems With extensive system and component examples-including what worked and what didn't-Process Analyzer Sample-Conditioning System Technology gives the new technologist a basic source of design parameters and performance-proven components as well as providing the experienced professional with a valuable reference resource to complement his or her experience.
