This article provides an overview of how computational fluid dynamics (CFD) works, and what benefits it can bring to the chemical process industries Sustainability, waste reduction, energy efficiency and increased demand for engineered material are driving process engineers to continuously…
Portable laptop computers and smartphones can be used to emulate computational fluid dynamics (CFD) modeling results using this interpolation procedure Most engineers are familiar with computational-fluid-dynamics (CFD) models and their power (for an overview of CFD, see Part 1). At…
The Dynasonics TFX-5000 ultrasonic clamp-on flow and energy meters (photo) are designed for non-invasive, ultrasonic transit-time measurement for use in water and wastewater treatment, heating, ventilation and air conditioning (HVAC) and oil-and-gas applications. TFX-5000 meters measure volumetric flow and heating…
Working with supercritical fluids poses challenges when designing heat exchangers. Some practical tips and precautions are presented here Industrial applications involving fluids at high pressure — pressure above the critical pressure of a particular fluid — are increasing in number.…
Researchers at the City University of New York Energy Institute (ccny.cuny.edu) have developed a low-cost battery based on manganese dioxide and zinc that reaches voltages of greater than 2 V, a first-time achievement that could allow batteries with these low-cost…
The model HD-3.5-9-SS ribbon blender features an integral bag-dump station that collects dust generated during manual dumping activities, improving worker safety and plant hygiene. Dust is drawn onto the cartridge filters of the dust collector, as nozzles within each filter…
The new LED light fixture (luminaire) for escape-path-marker signs (photo) is suitable for Zone 1/21. The sign is attached to a suspended panel, making it easily visible from both sides of an escape route from a distance of 30 m,…
This column is based on “2-Propylheptanol Production Process - Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/2-propylheptanol-production-cost. Also known as 2-PH and 2-propylheptyl alcohol, 2-propylheptanol is a branched fatty alcohol, primarily used in the production…
In low-temperature conditions, the use of compatible sealing materials is essential for leak-tight operation and proper functionality of pressure-regulating devices Harsh, frigid conditions are among the most challenging industrial environments (Figure 1) for fluid-handling applications. At these temperatures, it is…
Pumping hazardous chemicals requires specific shaft-sealing technologies to ensure containment and reliability Hazardous chemicals are defined by the Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) as those that are potentially harmful to human health and the environment. Existing as gases…
