How to Scale-Up Mixing Processes in Non-Newtonian Fluids
Christopher Henry , Robert J. Wilkens, Lew E. Gates
This article will describe the relationships that must be understood to scale-up fluid mixing processes in non-Newtonian, power-law fluids. The principles described apply to both close-clearance impellers, such as anchors and helixes, and to open...
Simulating Aqueous Processes
Joel B. Christian
Simulation that includes aqueous modeling can also account for full vapor/liquid/solid equilibria modeling, including redox chemistry.
Mining Intellectual Property for Profits
Daniel Pauly
A proverbial gold min may be buried within your patent portfolio. Here's how to capitalize on those assets.
Exposing Coriolis Mass Flowmeters' Dirty Little Secrets
James R. Reizner
Coriolis technology appears to be the perfect technology. But, upon closer inspection, a key flaw is revealed - the inability to accurately and consistently measure two-phase flow and aerated liquids.

Qualify your design methods for high-viscosity two-phase relief systems against these simple benchmarks. GeorgesMelhem-
People - The Key to Successful Project Management
Eldon R. Larsen
While Gantt charts, timelines, budgets, resource constraints, quality challenges, performance measures, and other tools are important, they are neither meaningful nor effective without people.
Pilot Plants - Part 1: Fast-Track Your Pilot Plant Project
Michael Dietrich, Paul Martin
These tried-and-true tips can streamline the design and construction of your pilot facility, while cutting costs.
Beware of Pitfalls of Carbon Dioxide Freezing Prediction
Steve Chafin , Tim Eggeman
Carbon dioxide freezing in a cryogenic system can result in plugging and other operational problems. This article offers insights into the carbon dioxide freezing phenomenon.
Use Logic Diagrams to Analyze Failure Mechanisms
Thiago Tinoco Pires
Here’s how to construct and apply continuous-value and single-value network diagrams, which can better represent system failure mechanisms than other logic diagrams.

Prevent Pulsation Problems in Piping Systems
Mark Corbo
Eliminate unnecessary damage in piping systems by following these guidelines to avoid pulsations from pumps and compressors.
Cost Management in Heat-Transfer-Fluid Systems
Conrad E. Gamble, P.E.
By taking ownership of fluid-related decisions for the entire life of the project, from design through dismantling, users can secure the best and lowest-cost approach in process heating and cooling.
The G-Value for Agitator Design: Time to Retire It?
Gregory T. Benz
This commonly used number does not correctly address the influence of viscosity, and has no relationship to performance parameters such as fluid velocity and blend time. This article recommends actual measures of agitator performance that should be...
