On-demand ammonia production from atmospheric air
Nearly all ammonia is produced using methane via the Haber-Bosch process, which requires high-temperature and high-pressure operation. A new portable prototype device developed by researchers from Stanford University (Stanford, Calif.; www.stanford.edu) and King Fahd University of Petroleum and Minerals (Dhahran,…
Fire and Explosion Safety: Going Beyond Traditional Protection
A sophisticated approach to fire and explosion safety requires one that expands conventional protection strategies to comprehensively consider storage, containment and tool compatibility Industrial fires and explosions are a serious risk to chemical processing facilities worldwide, threatening significant harm to…
Gas-Flow Calculations for Sonic Choking: Revisited
Gas compressibility can lead to choked flow in piping systems. Presented here is an overview of choked-flow geometries in pipes, and examples of how choked flow arises in different pipe layouts The more things change, the more they stay the…
