Long-standing partners TotalEnergies (Paris, France; www.totalenergies.com) and Veolia (Aubervilliers, France; www.veolia.com) have signed a memorandum of understanding for further cooperation in several key areas of energy transition and the circular economy, in line with their respective approaches to reduce their…
Hydrogen requires careful handling. It is colorless, odorless and highly flammable across a broad range of concentrations. As the lightest gas, it rises quickly and can accumulate in hard-to-detect areas. Without proper precautions, even a small leak can lead to…
Pressure vessels are weakened when nozzles must be introduced, and reinforcement is required to compensate. Presented here are two methods for calculating the necessary reinforcement When pressure vessels are penetrated for introducing nozzles, the vessel is weakened and must be…

Storing energy to smooth the intermittency of wind and solar power can be accomplished in a number of ways, including mechanical (pumped hydro, flywheels, compressed air and others), thermochemical (phase-change materials and molten salts, for example), chemical (conversion of electricity…
Sanitary valves are essential for applications that demand product purity, process integrity and regulatory compliance. This article discusses valve types, working principles and components, and provides considerations for selection and specification Sanitary valves are essential components for applications in the…
Even seasoned engineers can fall into the trap of trusting valve datasheets too much. In real chemical‑processing environments, “on paper” performance can fall short — especially when factors like backpressure, fluid phase, fire exposure, or piping layout are misunderstood. This…
