Mixture characterisation

Table 5.6 presents the results of a set of 5 maximum profit problems considered by Kerkhof and Vissers (1978). Each problem has different column configuration (i.e. different number of plates, N), handles different feed mixture (characterised by different relative volatility, a)y has different distillate product quality (xq), has different cost values (i.e. Pr, C0) and different set up times (ts). The initial charge, B0 = 100 kmol, V= 60 kmol/hr, t,= 1 hr, and Cf= 150 /hr. All cases deal with binary mixtures of different initial composition, xB0. 

The presence of an isosbestic point in Fig. 11 confirms the mass conservation between two mixtures characterised by the presence of anthropogenic organic matter (for treated effluent) and by nitrates (for river), the proportion of which varies according to the sampling place (river, effluent or mixture between discharge and river). 

The mixture characterisation of hot mix asphalt (HMA) also differs in MEPDG. The typical differences between the Guide for Design of Pavement Structures (AASHTO 1993) and the Mechanistic-Empirical Pavement Design Guide (AASHTO 2008) in terms of HMA mixture characterisation are shown in Figure 13.26.

However, the mixture characterisation of the PCC is different in MEPDG (AASHTO 2008) when compared to the empirical thickness design procedure given in the guide for design of pavement structures (AASHTO 1993). The typical differences between them are shown in Figure 14.14.
