Slope component balance line

Slopes of component balance (operating) lines. Equations (2.9) and (2.10) indicate that the slopes of the component balance lines are h V and LTV for the rectifying and stripping sections, respectively. As L < V [Eq. (2.11)] and L > V [Eq. (2.12)], the slope of the rectifying section component balance line is smaller than unify, while that of the stripping section component balance line Is greater than unify. 

In each case the point defined is the intersection of the line with the 45° diagonal line. The slopes and intersection points of each of these lines are summarized in Table 2.3, In addition, it has been shown that the rectifying section component balance line and the stripping section component balance line meet on the q-line,... 

If 17% benzene is unacceptable in the bottom product, reflux and reboil can be raised to achieve the required esparation in 10 stages. The slope of the rectifying section component balance line is increased, and that of the stripping section component balance line is lowered, ThiB is a trial-and-error calculation, which ende when 10 theoretical stages are accommodated betwean the componant balance line and the equilibrium curve, the top and bottom products are at their desired specifications, and the feed enters between stages 4 and 5. The slopes of the component balance lines will determine the new required reflux and boilup rate. The final result is shown in Fig. 2.10c. From this diagram,... 

Check that L fV is the same as that determined from the slope of the component balance line,... 

As the reflux ratio decreases, so does the slope of the upper component balance line, The effect of reflux ratio on the component balance lines is illustrated in Fig, 2,11, using the benzene-toluene system in Exampla 2.1. 

Slopes of component balance lines. These can be calculated from Eqs. 

Calculate the limiting vapor and liqnid flows for each section using Eqs. (2.64c), (2.64d), (2.65c), and (2,55d). Use these to determine the slopes of the component balance lines.

Product concentration in the permeate can then be determined either with numerical procedures or with graphic techniques. True reactor operating point at steady state is given by the intersection point of the straight line representing mass balance and the curve of the reaction term.8 10 99 As can be seen from Figure 7.2, for a-ketoisocaproate conversion to L-leucine, the slope of the convective term is reciprocally proportional to the mean residence time. If multien-zymatic systems are used as the biocatalyst, it must be outlined that the reaction term is the course of the reaction rate relative to the substrate conversion of the key component.10... 

Equation (3-47) is the equation of a straight line on the XY diagram which passes through the points (Xp K,) and (X2, Y2) with a slope of L VS. A mass balance on component A around plane z, and the arbitrary plane z = z in solute-free terms is... 

In a Y,X coordinate system, this equation gives a straight line of slope - Lj-/Gj- between the points Pj (A" , Y ) and PiiX, Y ) (see Fig. 1-48). Considering only one part of the separation unit (balance area BAII in Fig. 1-47), the mass balance of the exchanged component is...
