Predictive process models enable more efficient operations and higher-value products When they hear the words “process modeling,” some may envision an engineer sitting in front of a laptop waiting for a distillation column flowsheet to converge. While flowsheet simulations are…
New motors and drives provide energy efficiency and reliability in chemical applications Always on the lookout for ways to reduce downtime and energy costs, chemical processors are turning to advanced motors and drives to help achieve these goals. Sometimes as…
This column is based on “Hydrogen Peroxide Production Process Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/hydrogen-peroxide-production-cost. Hydrogen peroxide (H2O2) is the simplest peroxide (defined as molecules with two oxygen atoms covalently bonded to one…
Modern control systems for chemical processes can generate frequent alarms. This one-page reference provides information on common alarm-management metrics, which can foster focused remedial actions and ultimately lead to a safer, better-performing plant. Alarm frequency As alarm frequency increases, an…
Guard against gasket wear in plate heat exchangers Gaskets used in plate heat exchangers (photo) wear over time, due to natural aging, and the effect of temperature, pressure and stress that results from natural operating conditions. Getting the best performance…
The two experimental methods presented here can be used to quantify powder self-heating hazards in layer and bulk conditions in industrial processes Bulk storage of heated powders and powder accumulations on hot surfaces or in heated environments can potentially lead…
The new VMF-28/CP feeder with carbon package (photo) is a precision loss-in-weight measurement system designed specifically to provide accuracy in adding activated carbon (AC) in water-treatment operations. The new unit features an integrated scale for accurate feeding plus a bag-loading…
The VisuNet XT operator workstation features a high-bright LED-backlit LCD panel display with an optically bonded, glove-friendly and sunlight-readable 15- or 19-in. touchscreen for clear resolution in all lighting conditions.
