2006 Readers' Choice Survey
The equipment, services and suppliers selected to make a job easier greatly contribute to on-the-job success. The Readers' Choice survey identifies the leading vendors in more than 40 categories.
Acid scavenger prevents sticky problem
Development of ionic liquids that exhibit useful and unique properties has created huge untapped potential for commercial applications to increase operating efficiencies of many chemical production operations.
Are you certain about uncertainties?
Dr. Gooddata, therefore, recommends that we largely abandon the term bias. Instead, we will use the terms systematic error and systematic uncertainty. Systematic error is the actual error that exists between a measurement and the true value with zero random errors. Systematic uncertainty is taken to mean the estimate of the systematic errors limits that we could expect with some confidence.
Avoid Alarm Blunders
Ineffective alarm systems pose a serious risk to safety, the environment, and plant profitability. Too often, alarm system effectiveness is unknowingly undermined by poorly-configured alarms. Read about these 12 common mistakes that can undermine the management of your alarm system.
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.
Bend Pressure Drop & Heat Transfer Performance
The presence of bends and properly predicting pressure drop through them can have a significant impact on accurately estimating the thermal and hydraulic performance of the overall unit.
Better Design Is No Pipe Dream
The benefits of using pipeline simulation tools at the piping and instrumentation diagram (P&ID) level, rather than running simulations just on the process flow diagram, can often be overlooked.
Biomonitoring gets a going-over
The current state of biomonitoring is detailed in the much anticipated report issued July 24 by the Committee on Human Biomonitoring for Environmental Toxicants of the National Academies, Washington, D.C.
Boiling water is easy as one, two, three, four
Theres more to boiler level control than measuring level and adjusting a feedwater valve. Improved measurements and inverse response are just a few of the influences on operating boilers in a reliable manner.
BP tackles Texas City failings
British Petroleum's tragic March 2005 explosion has been well-documented through the press. Read here to find out how that tragedy spurred the development of a new program addressing management issues at BP.
CAGI to verify compressor claims
The compressed air industry is taking a step that will clear the air about the performance of its equipment. For the first time, many compressed air equipment manufacturers will submit their 50 hp to 200 hp lubricated rotary-screw compressors and 200 cfm to 1,000 cfm refrigerated air dryers to an independent laboratory for performance testing.
Can technologists make it to the top?
Having a background in engineering or science means you are more likely to want an executive with the same, according to Chemical Processing's Mike Spear.
