16.2 Relationship of HETP and HTU

In simple cases the HTU-NTU approach and the HETP approach discussed in Chapter 10 can be related with a derivation similar to that used for the Kremser equation (section 12.4). If the operating and equilibrium curves are straight and parallel, mV/L = 1, we have the situation shown in Figure 16-4A. The equilibrium equation is

while a general equation for the straight operating line is
