The new generation of high-efficiency IE5+ synchronous motors (photo) combine the benefits of this company’s modular system of gear units, motors and variable frequency drives (VFDs) with the possibility of reducing system variants through constant torque over a wide speed…
Digital transformation in the chemical process industries demands open architecture, enterprise-wide interoperability and a focus on sustainability. Progress discussed here is moving the industry in that direction Many companies in the chemical process industries (CPI) are currently pursuing digital transformations…
The MT100 Series multipoint mass flowmeter (photo) provides air-gas flow measurements to help optimize boiler performance and reduce fuel consumption and greenhouse-gas emissions. These devices feature compact thermal-dispersion flow-sensor technology. They accurately monitor and report the flowrate or the totalized…
Spring-loaded pressure-relief valves (PRVs) often use bellows to ensure balanced operation. Data analysis from 30,000 PRV service records across different industries and valve brands shows a bellows failure rate between 2 to 6%, according to Emerson (St. Louis, Mo.; www.emerson.com).…
This year marks Chemical Engineering’s 120th anniversary. At this extraordinary milestone, I paused to look into the history of the publication and its evolution to where we are now. The magazine evolved, changing its name to reflect changes and combinations…
Flow analysis can aid in simultaneously sizing pumps and associated piping systems. The concurrent sizing can reduce wasted energy and improve pump reliability In the chemical process industries (CPI), a variety of incredible process-simulation tools are available to provide greater…
Liquid-liquid extraction (LLE) is a separation technique that exploits differences in the relative solubility of compounds of interest (the solute) in two immiscible liquids — most often an aqueous phase and an organic solvent. This one-page reference reviews basic information…
When scaling up new processes involving complex feedstocks, such as biomass, well-defined mixing is key. Guidelines presented here will help to efficiently move biomass hydrogenation reactions from the laboratory to commercial-scale operations One of the most promising pathways to biomass-based,…
As dust collection becomes an integral part of chemical processes, monitoring and other technologies promote efficiency and performance Dust control has always been important in the chemical process industries (CPI) due to the often toxic and combustible nature of the…
HN Series Hydro Cyclones (photo) are designed to separate sand and other solids from water using centrifugal force. HN Series Hydro Cyclones are suitable for use in pre-filtration applications in membrane water-treatment systems. The HN Series is offered in three…
