Multi-agitator mixing systems for specialty applications
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…
A new electrolyzer module for this simulation software
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…
A digital pressure gage for use in mobile service applications
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…
Observing particle concentrations and velocities inside a fluidized bed
Fluidized beds are used in a variety of industries for combustion, drying, catalytic cracking and other processes. However, the process that occurs inside a fluidized bed is extremely complex and — due to a lack of effective measurement techniques —…
Minimizing the Effects of VOCs and Reactive Gases on Industrial-Grade LED Lighting
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…
Impact of Particle-Size Control on Bulk-Solids Flow Behavior
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…
Tower Doctor: Can the Cure be as Bad as the Illness?
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…
Easy-to-operate level-measuring devices
The new generation of Micropilot 80 GHz radar sensors (photo) — FMR60B, FMR62B, FMR63B, FMR66B and FMR67B — are suited for challenges when measuring points that are not easily accessible, located in dusty areas and harsh environments with extreme process…
Standard Operating Procedures are Critical for Boiler and Steam Operations
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…
Materials of Construction for the CPI
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…
