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…
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…
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…

The recycling plant…
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…
New membranes enable traditional water treatment and emerging energy transition applications While membranes and filters have provided a reliable and cost-effective solution for water desalination, purification and treatment as well as specialty process separations, innovative membrane and filtration technologies are…
Current hydrogen demand is dominated by petroleum refining and fertilizer production, and is supplied largely by fossil-fuel-based steam-methane reforming (SMR). Increasingly, however, demand for hydrogen will come from the energy transition, and will be supplied by a more diverse range…
Selecting the proper air-pollution control equipment for your process means focusing on the removal of specific pollutants while also ensuring that production goals are met Air-pollution control (APC) equipment is used to prevent pollutants from being released into the atmosphere…
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.…
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…
