Plant analysis procedures

Extended Plant-Performance Triangle The historical representation of plant-performance analysis in Fig. 30-1 misses one of the principal a ects identification. Identification establishes troubleshooting hypotheses and measurements that will support the level of confidence required in the resultant model (i.e., which measurements will be most beneficial). Unfortunately, the relative impact of the measurements on the desired end use of the analysis is frequently overlooked. The most important technical step in the analysis procedures is to identify which measurements should be made. This is one of the roles of the plant-performance engineer. Figure 30-3 includes identification in the plant-performance triangle. 

If the problem were accurately known, identification of which measurements should be taken would be exact. When the problem is initially not accurately known, the identification, measurement, and analysis procedure is iterative. Famiharity with the plant will help in identifying the measurements most likely to provide insight. 

Risk analysis A methodical examination of a process plant and procedure that identifies hazards, assesses risks, and proposes measures that will reduce risks to an acceptable level.

Washability analysis procedure used in a laboratory before preparation plant design to determine the cleaning processes to be employed and used during normal operation to evaluate the performance of the cleaning equipment and the amenability of the raw coal feed to the cleaning processes chosen (ASTM D-4371). 

The concept of essergetic functional analysis is introduced as a tool for approaching a condition known as "thermoeconomic isolation" of the interdependent equipment components of a system or process. If an interdependent component is thermo-economically isolated, then that component may be suboptimized with respect to many new, underlying variables. The required essergy analysis procedures are illustrated by considering the synthesis and design of components of a large steam power plant.

Several assay conditions were also tested to determine if the ELISA is applicable to analysis procedures for environmental samples. The assay was performed at pH s 5-9 and also in the presence of 0.02 - 2.0% bovine serum albumin. In addition, tap water, water collected from a rice field, and effluent water from a sewage treatment plant were spiked with alkaline-dissolved toxin and then assayed with the ELISA.
