Industry tackles a grave issue
End-of-life and other product stewardship initiatives will impact chemical plants. An agreement to lessen the environmental impact of chemicals production will have global ramifications. Meanwhile, European end-of-life directives on electrical and electronic equipment already are having a worldwide effect.
Wireless devices may get a shake up
Last months ISA Expo in Houston clearly showed how much attention wireless technology is attracting. However, concern about the reliability and life of batteries remains an issue. Thats why harvested or scavenged power is attracting interest.
Outsourcing innovation development
A new development method may allow breaking away from the pack as companies continue to employ outsource facilities that offer flexibility and foster innovation.
Check for human errors
You may be making an error if you dont find time to double-check your own and others work. Making time to check human work can prevent costly mistakes and save time.
Consider changing the speed not the pump
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.
Avoid trouble with slurries
Handling slurries (a mix of solids and liquids), should be based on experience and experiments, not theory. Much of the knowledge obtained from pneumatic conveyors and fluidization systems can be used in understanding slurries.
Keep measurements on the level
This article looks at six technologies mechanical floats and displacers, differential pressure, capacitance, ultrasonic, radar, and guided wave radar that are used most often for automated control, and provides practical guidance for choosing among them.
Rethink experiment design
The traditional approach to experimentation, often referred to as the scientific method, requires changing only one factor at a time (OFAT), but this method only allows one to see things one dimension at a time. By varying factors only at two levels each, but simultaneously rather than one at a time, experimenters can uncover important interactions.
Flowmeters clean and dirty
ControlGlobal.com contributor David W. Spitzer provides a look from a process automation perspective at how magmeters and Venturi meters are vying with ultrasonics for clean and dirty water applications.
Data validation: Jewel in the fieldbus crown?
Many users and most suppliers to the industry see process availability as the big payout benefit of Foundation Fieldbus (FF) diagnostics a good portion of it realized through data validation.
NeSSIs success should be a lock
The New Sampling/Sensor Initiative or NeSSI that replaces tubing, fittings and other hardware in a sampling system with miniature modular components makes sense. Enhancements now in the works should assure its success.
Tiny reactors aim for big role
Process Intensification (PI) has promised many things but has it fulfilled its promises? When looking at reactor technology, the answer is a definite Yes.
Industry can do well by doing good
Ignoring climate change could eventually damage economic growth, according to an authoritative report, says Mike Spear, editor at large, in this month's End Point column. Read more on the economics of climate change.
Making Your Process Operator-Proof
Senior Editor Dirk Willard discusses Shigeo Shingo's take on mistake-proofing, or Poke Yoke, if you speak Japanese. The practice suggests the following devices: eliminate redesign, facilitate guide, mitigate lessen the damage caused by the error, or flag identify the error.
Wal-Mart applies clout
Wal-Mart Stores, Inc., previously committed to reduce by 5% the packaging used by its 60,000 suppliers by 2013. Now, a new initiative uses a scorecard to tackle wasteful packaging.
Make jacketing your strong suit
Small details in jacketed-pipe configuration can have a big impact, according to Chemical Processing's Contributing Editor Andrew Sloley.
Gas up your sealing knowledge
As users become more familiar with gas seal technology and its advantages, gas seals are being applied to a wider variety of applications and equipment than ever before. As the seals gain in popularity know their advantages and disadvantages.
pH measurement faces acid test
Quest for more reliable readings prompts development of tougher and more-intelligent sensors. While pH control often plays a crucial role in processing, achieving reliable readings remains challenging at many sites. After all, pH sensors frequently serve in aggressive chemical environments.
