Description
Most engineers would agree that pumps represent the workhorse component in any chemical process industries (CPI) facility. Every day, countless decisions must be made related to the proper selection and specification, sizing and installation, operation and maintenance, and troubleshooting of these critical machines.
This Chemical Engineering reference book provides a wealth of practical engineering guidance on the proper use and operation of several different types of pumps.
Several articles focus on the sizing and selection of centrifugal pumps, and tips for managing the impact of pumps whose operation deviates from the best efficiency point (BEP). Others provide engineering tips for understanding and optimizing magnetically driven and sealless pumps, and guidance for calculating net positive suction head (NPSH).
Included is detailed information on condition monitoring and maintenance of pumps, recommendations for designing and operating safe and accurate pressure-relief systems, and selecting variable frequency drives (VFD) for centrifugal pumps.
Text also encompasses data related to lifecycle cost analysis, construction-cost indices for CPI equipment, and budget considerations for capital-intensive CPI operations.
These practical, how-to articles were originally published in Chemical Engineering.
Delivered in a PDF, 112 pages.
