Plant costs metallurgy

Moreover, information about the cost of materials presented in this text is limited to a few different MOCs. The approximate relative cost of some common metals is given in Table 7.10. As a very approximate rule, if the metal of interest does not appear in Appendix A, then Table 7.10 can be used to find a metal that has approximately the same cost. As the metallurgy becomes more exotic, the margin for error becomes larger, and the data provided in this text will lead to larger errors in estimating the plant cost than for a plant constructed of carbon steel or stainless steel. 

The Detal process is much simpler in design and construction because by-product neutralization and waste-stream treatment are not required. The elimination of equipment otherwise needed as part of the other two processes and use of much simpler metallurgy due to the lack of a corrosive environment results in a plant that is safe and easy to operate, as well as having much lower maintenance costs.
