Function event trees include primarily the engineered safety features of the plant, but other systems provide necessary support functions. For example, electric power system failure amid reduce the effectiveness of the RCS heat-removal function after a transient or small UJ( A. Therefore, EP should be included among the systems that perform this safety function. Siipfiort systems such as component-cooling water and electric power do not perform safety functions directly. However, they significantly contribute to the unavailability of a system or group of systems that perform safety functions. It is necessary, therefore, to identify support systems for each frontline ssstcm and include them in the system analysis. 

Conservation is a general concept widely used in chemical engineering systems analysis. Normally it relates to accounting for flows of heat, mass or momentum (mainly fluid flow) through control volumes within vessels and pipes. This leads to the formation of conservation equations, which, when coupled with the appropriate rate process (for heat, mass or momentum flux respectively), enables equipment (such as heat exchangers, absorbers and pipes etc.) to be sized and its performance in operation predicted. In analysing crystallization and other particulate systems, however, a further conservation equation is...

In all the foregoing discussion on reverse osmosis transport, system analysis and process design, no new chemical engineering principle Is Involved. But the manner In which the known principles are combined and expressed Is new the kind of results arising from such expressions Is new and the direction such approach sets for future work on the subject Is also new, all of which open a new area of chemical engineering. 

Notice that the right-hand side of Eq. (34) is equal to the ratio of the transformed concentration at the second measurement point to the transformed concentration at the first measurement point. In the terminology of control engineering, this quantity is the transfer function of the system between Xo and Xm- The Laplace-transform method is possible because the diffusion equation is a linear differential equation. Thus, the right-hand side of Eq. (34) could in principle be used in a control-system analysis of an axial-dispersion process.

Despite sharing only 25% sequence identity, structural analysis indicates that both proteins of E. coli NADP-IDH and T. thermophilus NAD-IMDH are homodimers which share a common protein fold that lacks the p p p motif characteristic of the nucleotide binding Rossmann fold [23], The strict and distinct specificities of these enzymes provide an attractive model system for engineering specificity, while the extensive knowledge of substrate and coenzyme binding and catalysis provide the sound foundation critical for rational design. 

The method just outlined and illustrated is route specific. It is very flexible and simple to use. It can also be easily computerized if the GP data can be fed in as numerical values. Here we have illustrated its use in the context of a cross-country pipeline, such as a crude oil, products, or perhaps slurry pipeline, which might be commonly encountered by chemical engineers. The method is completely adaptable to any hydraulic flow problem and could be used equally well for a short in-plant pumping system analysis. It can help the designer of flow systems to avoid sometimes subtle traps for slack flow and siphons that might not be immediately obvious if the mechanical energy equation is applied only once between the initial and final points of the flow system. 

The author believes that a large number of practical applications of thermodynamic analysis are possible before a level of complexity which is intolerable to an industrial process engineer is reached. Process design and development, equipment design, energy system analysis, and research guidance are a few of the areas where potential uses exist.
