Acetaldehyde (also known as ethanal) is an industrially important, highly reactive aldehyde, mainly used as chemical intermediate in the production…
The new 190 Series (photo) of control and shutoff valves features dye-forged pressure-containing parts (valve housing and bonnet), guaranteeing a homogeneous material structure without any discontinuities. Such microscopic defects, which are very difficult to prevent and to evaluate, especially on…
UniDisc (photo) is this company’s latest innovation for disc stack separators. This new disc technology is said to increase separation capacity by as much as 30%, while simultaneously providing an extremely high degree of hygiene. Unlike traditional separator discs with…
The new Aerzen Turbo G5 plus (photo) high-efficiency turbocompressor features air-foil bearings with a double coating of Teflon and graphite, which provides increased temperature resistance and a lifetime of more than 80,000 h of operation — independently from start and…
The new LMS200 magnetically actuated level-gage switch (photo) is non-invasive and designed to improve the ease of use, safety and reliability of magnetically coupled switches in demanding conditions. The level setpoint is easily adjustable without changing any process piping or…
Movitec multistage high-pressure pumps (photo) feature a new impeller that significantly improves the pumps’ suction characteristics, including net positive suction head (NPSH). The impeller is particularly suitable in applications with critical inlet conditions (for instance, boiler-feed applications), as well as…
The newest product in the Tab-Ex series of hazardous-area mobile devices (photo) is based on the latest Samsung Galaxy Tab Active2 and integrates augmented reality (AR) applications. With the Tab-Ex 02, users can communicate in realtime, as well as collect…
Since this company’s engineers have modified the standard rupture-disc design, its high-pressure rupture discs (photo) have become significantly more durable. The welding seam of the rupture disc is not stressed as usual, in terms of shearing and bending, but only…
Multi-product reactors with enhanced heat-transfer requirements are often equipped with simple radially working mixing systems with various types of impellers. To improve the performance of such reactors, this company has developed the Varioblade (photo), which is a flexible, modular impeller…
These key elements of internal boiler feedwater (BFW) treatment will help avoid boiler tube failures due to scale and pitting For many chemical processes, an industrial packaged-type boiler is a critical component for either power generation or for producing steam.…
