The Field Xpert SMT70 (photo) is a rugged tablet for commissioning and maintenance staff that manages field instruments and documents the work progress. The tablet comes pre-installed with the DeviceCare device configuration software and device library. The Field Xpert can…
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…
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…
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.…
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…
An adsorbent-based, sulfur-removal process for synthesis gas (syngas) that lowers capital and operating costs compared to alternative methods of removing sulfur has completed pre-commercial testing and has achieved commercial status. The Warm-gas Desulfurization Process (WDP; diagram) has been under development…
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,…
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 Gardner HE Series of U-trough ribbon mixers (photo) has mixing troughs with unconventional short aspect ratios (length to diameter). Short mixing times combined with low-energy, gentle action and high efficiency ensure that minor ingredients are dispersed homogeneously without the…
Vibration screening is one of the most effective ways to detect and prevent equipment failures or downtime, but performing vibration analysis can be complex. The new 3560 FC Vibration Sensor (photo) wirelessly and remotely captures simple vibration screening data on…
