The importance of having the inherent capability to meet operating requirements and enable proper instrumentation performance is stressed by Contributing Editor Andrew Sloley.
Small details in jacketed-pipe configuration can have a big impact, according to Chemical Processing's Contributing Editor Andrew Sloley.
A heat exchanger problem provides a textbook example of design limitations, according to Contributing Editor Andrew Sloley.
Chemical Processing's Contributing Editor Andrew Sloley advises that instead of reflexively resorting to brute force to provide enough head, adjusting the pump speed might make for a better solution.

Keeping liquid in a reflux drum still can prevent problems, says Andrew Sloley, in this month's Plant InSites column.
Sometimes things just dont add up as expected. Andrew Sloley discusses how sometimes two solutions aren't always better than one solution.
Software: Show Some Skepticism -- Calculated results require critical analysis.
Letters to the Editor -- Readers respond to the merits of helping youth to the dangers of running pumps dry.
Subcooling can complicate and compromise tower performance
Hydrostatic testing offers advantages but requires care
Various factors affect the choice and operation of liquid/vapor separators.
Cut Pump Speed to Cut Problems -- Lower rpm can translate into higher reliability.
Troubleshooting demands getting into the plant to inspect units
Properly Trigger Standby Pumps -- A pressure signal works for many but not all situations.
Affinity laws relate speed, head, capacity and power for different diameter impellers in a centrifugal pump. They allow quick estimates, but always remember actual performance will vary, especially if an impeller is cut down.
Removing water or moisture from a liquid stream is a critical operation in many manufacturing processes. Liquid stream dryers commonly contain either molecular sieves or adsorbents; during the last 20 years, the use of molecular sieves in process engineering has become much more common.
When measuring level, it’s important to recognize that the differences in the way process instruments work can profoundly affect readings.
To understand how to apply VFDs effectively, you must know the characteristics of the system and the equipment.
