Abstract
The invention disclosed herein provides methods for monitoring performance and efficiency for multi-effect evaporator systems. The invention also provides methods for monitoring the nonvolatile content of liquid products by determination of a boiling point rise. The invention involves monitoring methods that are improved over previous methods in view of their simplicity, and/or effectiveness, and/or, low cost. The methods of the invention enable system monitoring and problem diagnosis using measurements of a relatively small number of relatively easily accessible process operating parameters.
