A system of energy recovery depends on the process operation conditions from which it receives the energy when a Carrol-Water pair is used. To improve the performance of the energy recovery system, the variables of temperature, pressure and concentration must be in balance. External sensors for temperature and pressure may be installed for all components. However, concentration is not determined online, and therefore an indirect method must be considered, such as optical transmittance correlation. Humidity contamination accounts for the hygroscopicity of Carrol water samples.
The analysis of Carrol-Water optical characteristics is presented at multiple concentrations and temperatures, in which a transfer function involving absorbance and temperature is determined in order to define liquid pair concentration, as a function of actual temperature and signal intensity. This calculation provided the guideline to generate a control system that helps regulate thermal regimens. The characterization of this pair was made from temperature values ranging from 25 degrees C to 80 degrees C and mass concentration ranging from 51.79% to 66.2%.
