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 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 proper selection of materials of construction is crucial. The example presented here shows how to use standards to help narrow down the options Since the late 1800s, a steady body of pressure technology codes and standards have been under…
The new TL 305 series light towers (photo) provide bright and homogeneous illumination, indicating states, faults and ongoing processes clearly and visibly from a distance. The compact towers are available preconfigured with three, four or five segments. The new range…
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…
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…
Chemical plants should not overlook the potential problems that can arise from damaged or malfunctioning lighting fixtures It is no secret that many chemical plants and industrial sites are prone to harsh environmental conditions that can wreak havoc on equipment…
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…
The ES Series of spring check valves (photo) feature a PTFE-covered, stainless-steel spring for positive closing, as well as a new disc design for smooth, trouble-free operation. Compared to ball check valves, the ES Series requires very low liquid-head pressure…
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…
