Controlling flow in gas-handling applications can present challenges because of the fluids’ compressibility. This article presents an overview of how compressible gases behave in response to interacting variables Gas-handling operations are common in almost every sector of the chemical process…
Rare noble gases neon, krypton and xenon have unique properties and can be obtained from air, but the economics of isolating them at air-separation units depends on demand and pricing. This article provides information on their production and use The…
In order to recycle spent acids from different applications, a design approach based on different process modules gives operators the flexibility needed to handle different contaminants Spent or waste acids (SA) containing sulfuric or nitric acid are a byproduct of…
This overview of a number of different methods for handling spent acids will help operators select the technology most suited for a given application The most common pickling, leaching and passivation acids are the mineral acids: sulfuric, hydrochloric and nitric.…
Although Li-ion batteries are currently the dominant technology in the rechargeable-battery sector, sodium-ion (Na-ion) batteries possess many benefits in terms of sustainability, safety and costs, and are poised to greatly expand their commercial usage. Sodium-ion battery specialist Faradion Ltd. (Sheffield,…
One of the main problems in the conversion of greenhouse gases, such as carbon dioxide and methane, into liquid fuel or hydrogen is the development of coke- and sintering-resistant catalysts. Nickel on magnesium oxide (Ni/MgO) has long been identified as…
The TDLS8100 probe-type tunable diode-laser-spectrometer (TLDS) realtime gas analyzer (photo) makes quick and accurate in situ gas-concentration measurements, eliminating the requirement for sampling and conditioning components in industrial process-heating applications. These capabilities support safety improvements, emissions reductions, optimization of fuel…
The new Pascal CI4350 differential-pressure (DP) transmitter (photo) is equipped with filling-level software and can display differential and static pressure at the same time. The device has a high-definition graphic display, which makes comprehensive configuration possible, as well as simulations…
The new Semistat series of thermoelectric process thermostats (photo) are used to control temperature in etching processes in the semiconductor industry. Semistat S 1200 is an entry-level device that offers a small footprint with a cooling output of 1.2 kW…
The new Location Intelligence software (photo) expands the Simatic RTLS (realtime locating system) platform to include a digital twin of performance. The web-based software analyzes and visualizes dynamic data, processes events, and can be addressed directly from enterprise resource planning…
