An overview on the importance of standard operation procedures (SOPs) and how to write them Today, it is necessary to have standard operating procedures (SOPs) for steam and condensate systems, boilers, deaerators and even steam process units (Figure 1). An…
Henry Kister shares lessons learned from troubleshooting distillation towers During a course that I was presenting in Houston one year, a participant asked me the following at the end of one of the sessions: “Do you have experience with BX-type…
This company recently released an electrolyzer module in the new version of its ProSimPlus software (photo). By combining this module with other equipment from the ProSimPlus library, users can simulate the entire process of H2 production via electrolysis of water…
This company has engineered a purpose-built VM-450-gallon VersaMix (photo) that features three independently driven agitators, including a two-wing center-mounted agitator with contoured bottom and Teflon scrapers to efficiently motivate viscous product throughout the mixing zone, a long helical flight agitator…
Crushing and screening of solids are essential to many solids-handling processes, but engineers must be mindful about how those actions will affect flow behavior of the bulk material When it comes to processing bulk solids, (particle) size matters. Almost all…
The new CO2 Feed System (photo) is a safe and effective way to adjust pH and minimize risk associated with dangerous mineral acids. The 0–100% scaled flowmeter has an integral adjustment needle valve for increased accuracy. Additional benefits of the…
The model CPG1200 digital pressure gage (photo) enables flexible setting of operating pressures, readjusting pressure switches and carrying out pressure monitoring, for example, leak testing during transport. The battery-operated CPG1200 has been designed for use in mobile applications. Thanks to…
The ECO 500 (photo) is a high-performance melt filter for the filtration of heavily contaminated polymer feedstock. For chemical recycling, this technology is suitable for filtering low-viscosity polymers. The filter is self-cleaning, with a rotating, perforated drum, through which there…
Typically, when workers wear a face shield, they still have safety glasses on underneath. That is because most face shields have gaps on the bottom and sides that can let dangerous materials in. Conversely, Vader Combo (photo) is a face…
Regular heat-transfer-fluid monitoring can prevent fluid problems that lead to equipment failure, costly downtime and repairs. Parameters to watch include viscosity, acid neutralization number, moisture, solid or residue content, thermal degradation and flash point. This one-page reference provides information on…
