Design algorithms isothermal

To illustrate the usefulness of such an algorithm, and the seriousness of the issue of thermal conductivity degradation to the design and operation of PFCs, the algorithm discussed above has been used to construct Fig. 9 [34], which shows the isotherms for a monoblock divertor element in the unirradiated and irradiated state and the "flat plate" divertor element in the irradiated state. In constmcting Fig. 9, the thermal conductivity saturation level of 1 dpa given in Fig. 8 is assumed, and the flat plate and monoblock divertor shown are receiving a steady state flux of... 

All the reactions used thus far in this chapter have been ineversible reactions. The procedure one uses for the isothermal reactor design of reversible reactions is virtually the same as that for irreversible reactions, with one notable exception. First calculate the maximum conversion that can be achieved at the isothermal reaction temperature. This value is the equUibrium conversion. In the following example it will te shown how our algorithm for reactor design is etaily extended to reversible reactions. 

This is the conversion that will be achieved in a batch reactor for a first-order reaction when the catalyst decay law is second-order. The purpose of this example was to demonstrate the algorithm for isothermal catalytic reactor design for a decaying catalyst.

The Rachford-Rice procedure, described in 11.1.5 for LLE and in Problem 11.7 for VLE, is an example of a process analysis calculation. Using the equations from the Rachford-Rice procedure, develop an algorithm that could be used for the design of an isothermal VL flash process. That is, for given values of the product compositions x] and y and vapor fraction V, your algorithm should determine the required feed composition z, together with the T and P to be maintained in the flash chamber. 

In Chapter S, we will focus on the combine and evaluation building blocks, which will then complete our algorithm for isothermal chemical reactor design.
