Version 5.3a, the latest release of this company’s Multiphysics software (photo), provides many enhanced simulation capabilities for users of computational fluid dynamics (CFD) analysis, including up to 40% improved performance for algebraic multigrid (AMG) and 20% for geometric multigrid (GMG)…
When it comes to managing complex global supply chains, visibility and collaboration are the name of the game. To drive it, companies are embracing digital strategies The global chemical process industries (CPI) are undergoing a major transformation brought about by…
Working in extreme environments can take a toll on workers, but these dual-action personal air conditioners (PACs; photo) keep workers comfortable in either hot or cold working conditions. PACs minimize heat stress and fatigue in elevated temperatures, or with simple…
When wearing single-use protective gloves, sweat can create health and safety issues. Presented here is a look at the causes of the problems and possible solutions A great many situations across the chemical process industries (CPI) require quality hand protection,…
This column is based on “Cyclohexane from Benzene and Hydrogen – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/cyclohexane-production-cost. Cyclohexane is a relatively stable cycloalkane, present in crude oils in concentrations of 0.1–1.0%. This cycloparaffin…
The concept of tray stability can apply to bubble caps and be used as an alternative method to determine the minimum efficient capacity of these devices. A new stability correlation for bubble-cap trays is proposed and checked against FRI data…
Differential-pressure (DP) level measurements are widely used in chemical and petrochemical facilities, thanks to their reliability and ease of use. Recent advances are making them even more reliable and easy to use Differential pressure (DP) level-measurement technology (Figure 1) is…
The 2018 Connected Plant Conference (www.connectedplantconference.com) will take place February 26–28 in Charlotte, N.C. Focused on digitalization and connectivity trends in the chemical process industries (CPI), as well as the power-generation sector, the event’s technical program boasts speakers from a…
A practical look at the need for validation, as well as conceptual considerations and a case study This article addresses the need for experimental validation of computer-generated distillation column simulations , and discusses the main concepts involved with experimental validation.…
Process industry plants install sophisticated air-pollution control systems, but they can be ineffective if the flowmeters on which they rely deliver inaccurate or unreliable data. This one-page reference provides information on measuring the flow of gaseous combustion products in large…
