Temperature measurement is a common control parameter in distillation cooling and heating processes. Depending upon the application and process fluid, temperature control may be used for cooling distillate to condense high volatility products into liquid phase, or heating of process fluid to vaporize the high volatility components for easier separation.

For safe operations and maintenance, it is important employees know what is inside the pipes they are working around to prevent accidental exposure to hazards. If the contents in a pipe may be hazardous, that information should be clearly communicated as a matter of human safety.
