Measuring temperature is required in nearly all chemical processes, but engineers often struggle with implementation. Here are suggestions to avoid common pitfalls Measuring temperature in chemical processing applications remains, arguably, the most misunderstood of the four main process variables, which…
This company has received TEX, IECEx, and UKEx certifications for its IRmadillo process analyzer (photo) for use in high-temperature liquid processes up to 220°C (428°F). These Ex certifications rate an analytical instrument as safe for use in hazardous environments, including…
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).…
A next-generation intelligent valve controller for any valve Introduced at Valve World Expo and Conference 2022 (November 29–December 1; Düsseldorf, Germany), the Neles NDX 2.0 (photo) is a next-generation intelligent valve controller offering more sustainable valve-control performance for all process…
The new Ethernet-APL HART Converter (HM-APL-PCB; photo) enables transmitter manufacturers to easily convert existing HART transmitters to the new Ethernet Advanced Physical Layer (APL) interface. The printed circuit board (PCB) can be customized to incorporate special features or size requirements.…
In a typical bulk-solids pneumatic-conveying system, an air mover is used to generate the necessary air flowrate and pressure required to transport a solid material through a pipeline at a given rate. This one-page reference discusses the operating mechanisms and…
With the vipro-PUMP series (photo), this company is launching a totally new generation of dispensers. A new design, optimized dosing components and modular construction provide numerous opportunities for adapting the dosing equipment even more effectively to the relevant application. The…
Potential maintenance and repair cost savings are significant when employing vapor corrosion inhibitors either as a standalone mitigation technique, or as a complement to conventional cathodic protection methods, in aboveground storage tanks Mitigation of external corrosion on the bottoms of…
Scientists from Nanyang Technological University, Singapore (NTU Singapore; www.ntu.edu.sg) have developed a technique to convert waste paper, from single-use packaging, bags and cardboard boxes, into electrodes, which can be made into rechargeable batteries that power mobile phones, medical equipment and…
This company has launched a new specialized thermistor variant aimed at mid-range temperature-sensing tasks for tight-tolerance instrumentation in non-condensing moisture environments. The ENTC-EI-10k9777-02 thermistor (photo) is based on a Stycast epoxy-encapsulated core with Kynar insulation for maximum durability across a…
