          and communication. The technology provides access to comprehensive, real-
          time data, alarms, and reports that help to speed resolution of issues and pro-
          mote collaboration on continuous improvement and value creation. This
          component is instrumental in creating, capturing, and delivering value to
          the users of the technology.


          11.2.5 Case Study

          3D TRASAR Technology for Sugar equipment was installed at a large raw
          sugar mill. The mill faces water scarcity and consequently reuses process
          condensate in its low-pressure boilers. For monitoring the process conden-
          sate quality, an a-naphthol test was done every 15 minutes. In Figure 11.7,
          the performance of the conductivity sensor is shown. The crosses represent
          the a-naphthol data points from the operator logs. The results from the test
          are qualitative and are logged as nil, trace, very faint, and so forth, depend-
          ing upon the color intensity of the ring that develops for the sample under
          test. The a-naphthol test data indicates that there is an entrainment event
