Temperature measurement in distillation processes
What are the differences of thermocouples and RTDs and where should they be used?
Temperature measurement is a common control parameter in distillation cooling and heating processes. Temperature control relates to product quality, process optimization and stability, resulting in improved plant safety and reduced process energy costs. While a seemingly simple parameter, understanding the importance of temperature measurement is critical to running a distillation column at peak efficiency.
TCs, RTDs and sensor advancements
In this article, we’ll consider various cooling and heating distillation processes, how thermocouples (TCs) and resistance temperature detectors (RTDs) compare in these and other applications, and some recent advances in sensor technology.
