Biomethane Last month, NextChem, a subsidiary of Maire Tecnimont S.p.A. (Rome, Italy; www.mairetecnimont.com) was awarded a contract by ENGIE subsidiary Storengy (Bois-Colombes Cedex, France; www.storengy.com) to perform an advanced basic-engineering study for a plant that will produce second-generation biomethane from…
Advances in sliding-vane and internal-gear seal-less pump technologies can provide many benefits when compared to centrifugal pumps or more well-known positive-displacement pump options Facilities in the chemical process industries (CPI) use a wide array of flowing substances that must be…
Currently, enhanced biological phosphorus removal (EBPR) techniques in municipal wastewater-treatment plants (WWTPs) do not work well at temperatures above 25°C, which is common in warm countries. This limitation is expected to extend to more countries with the advent of global…
New hardware combined with monitoring technologies can help optimize combustion now and in the carbon-conscious future Combustion has long been a delicate balancing act. Chemical processors want their combustion systems to be fuel efficient and available for use, while at…
Alternating-current (a.c.) induction motors are widely used throughout the chemical process industries (CPI) and other manufacturing sectors to convert electrical energy into mechanical energy to power rotating equipment, such as centrifugal pumps, compressors and fans, as well as other industrial…
Presented here is a fast and flexible solution that removes solids, traces of water and gel in a single operation, therefore significantly reducing the time it takes to perform the process during silicone production Reliable silicone manufacturing operations depend on…
Henry Kister shares lessons learned from troubleshooting distillation towers On an assignment to troubleshoot a vacuum tower for a petroleum refinery, my team was tasked to “run simulations to determine why the heavy vacuum gas oil (HVGO) has a very…
Presented here are practical points to help in the selection of plate-and-frame and air-cooled heat exchangers With a wider variety of heat exchangers to choose from than ever before, there are a number of variables to be considered when assessing…
Dispersion modeling of atmospheric releases from pressure-relief valves and other sources can be time-consuming. Follow this screening process to categorize which installations require detailed modeling and focus effort where it is most consequential The safe design of atmospheric relief/venting systems…
Track pump operation with this monitoring system This company has developed Smart Monitoring for its ecoflow and triplex metering and process diaphragm pumps (photo). A combination of sensors integrated into the pump and software-based evaluation provides the user with comprehensive…
