When it comes to managing regulatory documents such as product labels, bills of lading, and certificates of analysis (COA), virtually all manufacturers in the chemical process industries (CPI) face the same challenge — getting the right information into the right…
To unearth the fundamental causes of vibration-related pump troubles, pump end-users and original equipment manufacturers (OEMs) typically have relied on a concise array of vibration field-test parameters. Conventional trial-and-error vibration troubleshooting methods often fail to achieve the longterm, trouble-free pump…
OVERVIEW Indirect heating of processes by organic thermal-liquid fluids offers highly reliable operation, and the heat transfer systems are generally treated as low-maintenance utilities. Occasionally, the heat transfer fluid can become contaminated, resulting in the formation of sludge particles, or…
Pinch analysis emerged as a systematic design tool during the energy crisis of the late 1970s, particularly for the optimization of heat-exchanger networks and other heat-recovery systems [ 1 ]. Since then, ongoing breakthroughs in the use of pinch analysis…
Acoustic coupling in industrial furnaces is an issue that appears to have become more prevalent as designs increase the volumetric heat density of furnaces, and burner technology is required to meet more-stringent emission requirements. The problems associated with acoustic coupling…
Relief systems are the last line of defense for chemical process facilities. Verifying their capability to safeguard equipment integrity becomes important as process plants age, increase their capacities to adjust to new market requirements, undergo revamps or face new environmental…
Storage of bulk materials in hoppers, bins and silos is ubiquitous in the chemical process industries (CPI), and so are the challenges that go along with it. Flow stoppage (bridging or arching), variability in mixture composition (de-mixing or segregation), erratic…
Reduction of greenhouse gas (GHG) emissions continues to be a major issue in national and international public policy, as well as a major focus for companies in the chemical process industries (CPI). Many countries are considering systems that place a…
In 1952, 37 companies established Fractionation Research, Inc. (FRI). Most of those original members are now gone or absorbed by other companies. Nevertheless, their goal was to study distillation in columns having diameters and heights that were similar to industrial…
