Performance improvement cycle system effectiveness

The work performed by the system lowers the temperature of the exhaust gases to -2200 K, where the gases can be effectively utilized by conventional steam-driven power generating plants. Thus, by use of an MHD topping cycle, both the first and second law efficiencies of conventional power plants can be improved. 

Improvement cycles, at all levels, are conceptually a process of Planning, Doing, Studying (progress and performance), and then Adjusting plans based on results. We ve addressed the Plan and Do steps. In the third role, operations effectiveness and efficiency, we U discuss the role of measurement in the Study process and outline how to build more effective measurement systems—yet another key role for ISEs in the work to achieve full potential performance. 

Figures 9.10 and 9.11 show the effect of total feed amount admitted per cycle on product purity and recovery for both the standalone PSA unit and the integrated system. The results obtained for two different values of A, 25.5 bar and 35.5 bar, show that for the same separation performance, the hybrid system withstands a higher feed throughput than the PSA operating alone. Increasing the feed flow rate results in longer bed coverage at the end of the HPA step, thus improving both purity and recovery. If the total feed amount admitted per cycle exceeds 65 L (STP), the H2 product is diluted with CH4...

A list of the 64 analytes and their method performance is shown in Table 6.6. The increased number of analytes is possible because of improvements to the collision region of the MS/MS system that provide increased sensitivity and reduced memory effects. In addition, robotic systems for sample handling and on-line solid-phase extraction (SPE) of plasma samples were integrated with the LC/MS/MS system (Figure 6.22). An isocratic reversed-phase HPLC method provided a cycle time of 4.5 min per sample. The on-line sample preparation and short analysis resulted in an increased sample throughput that required less time from the scientist. The... 

Note that a re-configuration of the logistical system may lead to an improved logistical performance (e.g. faster cycle time) and may influence the determination of target stock levels. However, this effect is not investigated here.
