Henry Kister shares lessons learned from troubleshooting distillation towers In 1988, the author led a team to troubleshoot a chemical tower that was revamped to achieve a small increase in capacity (up to 4%) by increasing the tray hole areas…
A portable pipe beveling tool prepares pipe for welding The Wart Millhog Portable Pipe Beveler (photo) is a right-angle I.D. clamping tool for performing any angle of end prep on 0.75 in. I.D. to 4-in. O.D. pipe of different schedules.…
Compliance with industry- and machinery-specific safety standards and classifications is essential to make the safest possible environment for plant personnel, especially those working in potentially hazardous conditions Navigating the world of industrial safety standards can feel like being in uncharted…
Heat transfer fluids (HTFs) provide heating and cooling of process equipment, including reactors, autoclaves, distillation columns, reboilers, mixers and dryers. HTF system designs should provide for effective system venting, both of residual water at startup and of degradation products during…
Cyclopropane-functionalized hydrocarbons can be excellent fuels because of their high energy densities, but organic synthesis of such fuels is difficult. In work recently published in the journal Joule, a research team led by Jay Keasling at the Joint Bioenergy Institute…
Advances in sliding-vane and internal-gear seal-less pump technologies can provide many benefits when compared to centrifugal pumps or more well-known positive-displacement pump options Facilities in the chemical process industries (CPI) use a wide array of flowing substances that must be…
Understanding the working principles of scrolling and pushing centrifuges can help when deciding which type to use. Feed properties and other factors also play a role When looking for a proven solution for mechanical dewatering, you will most likely come…
Ethernet Advanced Physical Layer (APL) provides connectivity between field-generated data and enterprise systems. Presented here is information on the design and operation of this rapidly expanding technology Process plants today have vast amounts of data available at the field level…
