Feature Report PSA Technology: Beyond Hydrogen
Purification Pressure swing adsorption (PSA) technology is well known
for H2 purification applications, but the technique can also be used for other
gas-separation processes in petroleum refining facilities
Engineering Practice Illuminating Process Vessels:
Diffused Light is Better What appear to be scratches on a vessel
sight glass may be an illusion caused by improperly applied LED lighting
Solids Processing Hopper Design Principles
When hoppers are designed without consideration of the actual materials being
handled, problems inevitably arise. Follow this guidance to avoid common
solids-handling issues, such as erratic flow and no flow
