There are several cost indices used by the chemical industry to adjust for the effects of inflation. Several
of these cost indices are plotted in Figure 7.3.

Figure 7.3 The Variations in Several Commonly Used Cost Indexes Over 15 Years (1992–2006)

All indices in Figure 7.3 show similar inflationary trends with time. The indices most generally accepted

in the chemical industry and reported in the back page of every issue of Chemical Engineering are the
Marshall and Swift Equipment Cost Index and the Chemical Engineering Plant Cost Index.

Table 7.4 provides values for both the Marshall and Swift Equipment Cost Index and the Chemical

Engineering Plant Cost Index from 1991 to 2006.
