Fluid mixing is a unit operation carried out to homogenize fluids in terms of concentration of components, physical properties, and temperature, and create dispersions of mutually insoluble phases. It is frequently encountered in the process industry using various physical operations and mass-transfer/reaction systems (Table 1). These industries include petroleum (qv), chemical, food, pharmaceutical, paper (qv), and mining. The fundamental mechanism of this most common industrial operation involves physical movement of material between various parts of the whole mass (see Supplement). This is achieved by transmitting mechanical energy to force the fluid motion. 

The concentrations of component 2 on the plateau downstream of the first shock are then calculated from... 

If the reaction is of the form A—the concentration of component B can be determined from the stoichiometry ... 

Figure 5-38 shows plots of the dynamic response to changes in the inlet concentration of component A. The figure represents possible responses to an abrupt change in inlet concentration of an isothermal CFSTR with first order irreversible reaction. The first plot illustrates the situation where the reactor initially contains reactant at and...

Generally, at any moment of time the concentration of components within a vapor cloud is highly nonhomogeneous and fluctuates considerably. The degree of homogeneity of a fuel-air mixture largely determines whether the fuel-air mixture is able to maintain a detonative combustion process. This factor is a primary determinant of possible blast effects produced by a vapor cloud explosion upon ignition. It is, therefore, important to understand the basic mechanism of turbulent dispersion. 

Here is the concentration of component a, is the single site t-matrix, Af E) is the scattering path operator and is the matrix element with respect to Xqx-... 

Pi = initial low pressure or vacuum, inmHG Yo = initial concentration of component (oxidant) under low pressure, mol fraction n]-i = number of mols at pressure condition n = number of mols at atmospheric pressure or low pressure conditions... 

Next, let s consider the spectrum of a sample that contains 2 concentration units of Component 1 and none of Component 2. In this perfectly linear, noise-free case, when we double the concentration of Component I, the absorbance at each of the wavelengths will also double. We have also plotted this second spectrum in Figure 29. It lies along the same direction from the origin as the first spectrum and at twice the distance.

A rough estimate of the concentrations of components in a mixture can be obtained using peak areas. This method assumes that the area percent is approximately the weight percent. The area of each peak is divided by the sum of the areas of all peaks,... 

The concept of average residence time, or turnover time, provides a simple macroscopic approach for relating the concentrations in ocean reservoirs and the fluxes between them. For the single box ocean in Fig. 10-17 the rate of change of the concentration of component n can be expressed as... 

Example 1.3 Find the outlet concentration of component A from a piston flow reactor assuming that A is consumed by a first-order reaction. 

There are two uses for Equation (2.36). The first is to calculate the concentration of components at the end of a batch reaction cycle or at the outlet of a flow reactor. These equations are used for components that do not affect the reaction rate. They are valid for batch and flow systems of arbitrary complexity if the circumflexes in Equation (2.36) are retained. Whether or not there are spatial variations within the reactor makes no difference when d and b are averages over the entire reactor or over the exiting flow stream. All reactors satisfy global stoichiometry. 

Find the batch reaction time that maximizes the concentration of component B in Problem 2.10. You may begin with the solution of Problem 2.10 or with Equation (2.23).
