The V-Cone Blenders utilize diffusion as the main mechanism for mixing. As the V-shaped vessel rotates on its horizontal axis, batch materials cascade down, distributing particles over a freshly exposed surface. With operating speeds of 5 to 25 rpm, this…
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.…
These air mixers (photo) are designed for maximum efficiency and ease of use in diverse mixing applications. Compatible with a range of mixing blades, these air-powered devices are intrinsically safe for handling of volatile and flammable materials when electric mixers…
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…
In this exclusive interview, Jens Cuntze, member of Clariant’s Executive Steering Committee, offers his perspective on the goals, challenges and accomplishments of the Business Unit Catalysts, as well as the challenges faced by the chemical process industries Jens Cuntze is…
In a first-of-its-kind trial project, a CO2-removal method known as enhanced rock weathering (ERW) is being combined with biotechnology to accelerate atmospheric CO2 sequestration. FabricNano (London, U.K.; www.fabricnano.com) and Veolia (Paris, France; www.veolia.com) have embarked on a partnership wherein enzymes…
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…
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…
This company has introduced new 6- and 8-in. valve sizes for its Model CV valve product line (photo). The new valves are available in actuated and manual versions with both featuring a Class 150 pressure rating. Additionally, the company is…
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)…
