Following Flow by Mapping Heat
Infrared imaging provides insight into distillation process.
by Hank Hogan, Contributing Editor
Researchers at Zhejiang University of Technology in Hangzhou, China, have found that a little bit of warmth can go a long way when it comes to understanding the distillation process. The group used a thermal infrared camera to track the flow of warm and ambient-temperature water across a distillation tray.
The scientists also determined how long the water spent at given locations and, thus, its residence time distribution. Their technique could provide a simple, direct and accurate indication of residence time distribution in complicated setups, which could benefit distillation processes in a variety of industries...
