Hydrogen Production via Methane Pyrolysis: An Overview of ‘Turquoise’ Hydrogen
‘Turquoise’ hydrogen processes generate H2 without releasing CO2. Presented here are the opportunities and challenges for producing hydrogen by methane pyrolysis Hydrogen-producing processes are classified using a color scheme according to their carbon footprint (Table 1; [1–3]). So-called “turquoise hydrogen”…
The shortness of time . . .
As I get older, time seems to get shorter. Although many experience this feeling, the duration of time is not changing, only our perception of it. However, in the five decades I have been involved in science, the timescale at…
Management and Maintenance Strategies for Valves
Asset criticality and risk are primary among the many factors that must be considered to appropriately manage valves throughout their lifecycle Asset strategies usually define how assets will be treated in the different phases of an asset lifecycle, from acquisition…
A new heat-resistant membrane
Most polymeric membranes degrade during use, making them impractical for industrial separation processes. To solve this problem, researchers from the State University of New York at Buffalo (SUNY Buffalo; www.buffalo.com), with cooperation for scientists at Rensselar Polytechnic Institute, have created…
Solids Flow Measurement in Specialty Chemicals: Seamless Integration
Continuous flow measurement is used at this Austrian specialty chemicals manufacturer for process optimization, as well as overload protection Sensing-plate weighing systems are often used for weighing free-flowing and very dusty bulk materials.
