Electrochemical amalgamation effectively removes mercury from concentrated H2SO4
It is well known that mercury is not only toxic, but is also highly mobile. As a result, Hg emissions from both industrial processes (gold mining, combustion of fossil fuels, cement production, waste incineration and more), as well as natural…
Carbon nanotube coating could expand the applications for superlubricity
When a sliding interface experiences a coefficient of friction (CoF) below 0.01, the situation is said to have superlubricity. In the past, superlubricity has been limited to the microscale in controlled environments, and to ceramic surfaces with polar-fluid lubrication. Now,…
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 —…
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…
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…
