When transferring stored bulk-solids materials from hoppers, bins and silos, flow stoppage can occur because of bridging or arching at the vessel outlet. Hopper outlets must be large enough to prevent cohesive arches or stable ratholes from developing. Determining the…
Even with advanced predictive technologies, unplanned equipment failures can still occur. In these instances, as shown in this boiler example, rapid maintenance action is crucial to minimize downtime Maintenance activities generally fall into two categories — reactive and preventative. The…

Polypropylene carbonate (PPC) is a thermoplastic polymer produced from the catalyzed copolymerization of carbon dioxide (CO2) and propylene…
When making a change in your process, do not overlook new potential hazards that may arise, as discussed here Large-scale chemical processing can be inherently risky. This is especially important to keep in mind when making changes to a process.…
Accurate interface level measurement is crucial to optimizing separation processes. Today’s guided wave radar technologies make it possible to measure thin liquid layers with greater accuracy than ever A bottle of salad dressing can illustrate a challenging level measurement application.…
A holistic approach to bulk-solids-feeding installations can improve the effectiveness and efficiency of operations involving solids handling Many chemical processes involve the extraction of bulk solid materials at a controlled rate from a storage vessel for delivery into the process.…
A step-by-step approach is presented to address the modern requirements of a pump-system digital solution In recent years, significant developments have been achieved in the fields of cloud computing and machine learning techniques. In conjunction with increased awareness regarding the…
Understanding project risks is critical to arriving at useful cost estimates. Since each capital project in the chemical process industries (CPI) is somewhat unique, it can be difficult for engineers and project leaders to price risks in their estimates and…
Meeting the wastewater-treatment demands of an integrated manufacturing complex demands a design that can address a diverse array of contaminants and discharge requirements Any large, integrated chemical-manufacturing complex will require the implementation of a comprehensive wastewater-treatment solution to address unique…
