Advances in H2S-removal technologies for biogas upgrading are essential for mitigating environmental issues like air pollution and corrosion Biogas, a renewable energy source derived from organic waste and typically comprised mainly of methane, holds great promise for sustainable energy production.…
Traditionally, many polymerization reactions are carried out batchwise in reactor vessels, with the reaction taking place in solution, emulsion or in a melt. This procedure reaches its limits if, for example, the reaction is very exothermic or the viscosity increases…
The ecoflow LDC1 M910S (photo) has a hydraulic output of 0.2 kW and was equipped with an Ex motor due to the hydrogen produced during the process. In accordance with the requirements of the application, it conveys water at up…
The efficiency of steam-generating and distribution systems can be improved incrementally, but more substantial gains can be found using pinch analysis for better heat recovery When it comes to improving the energy efficiency of a thermal system, most industrial organizations…
Calcium-sulfonate complex greases are widely used in applications in the pulp-and-paper, marine and steel-manufacturing sectors. Within an ever-volatile lithium market, calcium-sulfonate greases are increasingly seen as a reliable alternative to lithium-based greases. However, typical methods for preparing high-performance calcium-sulfonate grease…
Lime Injection Engineers at the Institute for Technologies of Metals (ITM) at the University of Duisburg-Essen (Duisburg, Germany; www.uni-due.de), together with Fritz Winter Eisengießerei GmbH & Co. KG (FW; Stadtallendorf; Germany) and the FEhS – Building Materials Institute e.V. (Duisburg)…
A research team led by Kenneth C. Neyerlin at the National Renewable Energy Laboratory (NREL; Golden, Colo.; www.nrel.gov), with members from Argonne National Laboratory (Lemont, Ill; www.anl.gov) and Oak Ridge National Laboratory (Tenn.; www.ornl.gov) has developed a membrane electrode assembly…
An Oak Ridge National Laboratory (ORNL) team created and tested two different formulations for stationary batteries that could utilize CO2 from industrial sources while storing energy from wind turbines and solar panels. Consisting of two electrodes in a saltwater solution,…
In 1851, the year that the first America’s Cup sailboat race was contested, the top speed for a wind-powered vessel was 10 knots. Over the next 100 years, top sailboat speeds barely budged, but by the mid-1970s, top sailing speed…
Electrification will be a key factor in decarbonizing hard-to-abate sectors, but challenges arise in applications that require very high temperatures, such as steel production. The intense heat requirements for converting iron ore into metal contribute significantly to the CO2 emissions…
