Corrosion Prevention for Heating and Cooling Systems
Understanding that viable strategies exist to protect essential cooling and heating systems from corrosion is a crucial step in ensuring proper asset protection Several years ago, a manufacturing plant was forced to unexpectedly shut down one of its main production…
A hub for the digitalization of data from safety devices
Whether in the engineering of large and distributed automation projects, in the diagnosis of faults or in regular testing, the specification, configuration and maintenance of safety devices in process plants requires effort and careful attention. If new functions are added…
Sand-based thermal-energy storage
Using concentrated solar thermal (CST) energy to supply industrial-heating requirements is a promising way to reduce the use of fossil fuels. This is the aim of Magaldi Green Energy (Rome, Italy; www.magaldigreenenergy.com), which developed its Solar Thermo Electric Magaldi (STEM)…
Converting a steel mill to climate-neutral steel production
To decarbonize steel production and its high carbon dioxide emissions, Fraunhofer researchers, TS Elino GmbH (Dürren; www.elino.de) and Salzgitter AG (all Germany; www.salzgitter-ag.com) are working on converting an existing steel mill to climate-neutral production methods. The aim is to produce…
First commercial DAC facility in the U.S. captures CO2 for concrete
In November 2023, Heirloom Carbon Technologies (Tracy, Calif.; www.heirloomcarbon.com) unveiled the United States’ first commercial direct air capture (DAC) facility, which can capture up to 1,000 ton/yr of CO2. The process first uses renewable energy to remove CO2 from limestone…
This new stainless steel is ultra-resistant to corrosion
One of the major hindrances in saltwater electrolysis for “green”-hydrogen production is the cost of materials to construct electrolyzer components that can withstand an extremely corrosive saltwater environment. Currently, titanium coated with platinum or gold is usually required for such…
Optimized dosing solution for drip applications
The newly developed vipro-Pump MR series (photo) offers plant operators a virtually maintenance-free dispenser that doses all conventional impregnating resins — even chemically aggressive ones. A patent application has been filed for the vipro-Pump MR and the associated process. The…
Optimization of Spray Drying with Exhaust-Gas Recirculation
Energy recovery in spray-drying processes can reduce production costs, but involves trade-offs. Using milk powder as an example, this article describes a spreadsheet method to evaluate exhaust-gas recirculation scenarios for optimizing spray drying Dairy processing is among the most energy…
Bulk material feeder ensures consistent product flow
The Feedos S bulk material feeder (photo) automatically meters and doses powders and other dry materials with the high accuracy and consistency needed to optimize continuous processes. Featuring a proprietary design, the Feedos S is engineered with optimized geometry that…
Accurately dose smaller volumes with this system
Standard load cells enable mechanical dosing with an accuracy ranging from 0.2 to 1%. This means that you can accurately dose 10 kg down to 20–100 g or 1,000 kg down to 2–10 kg. However, for mixing small product volumes,…
