However, it cannot be decided at present which processes (degree of seawater-rock interaction or mixing ratio of seawater, igneous water and meteoric water) are important for the generation of Kuroko ore fluids solely from the isotopic studies. But experimental and theoretical considerations on seawater-volcanic rocks interaction and origin of hydrothermal solution at midoceanic ridges suggest that Kuroko ore fluids can be produced dominantly by seawater-volcanic rock interaction.

The results demonstrated a wide range of toxic effects and loadings for textile effluents (Tab. 13). Inter-effluent toxicity differences could be attributed to factors such as type of industrial process, degree of waste treatment, variability of effluent composition and dilution by process waters. Toxic loads from industries 9 and 10 indicate they contribute the greatest toxic load to the receiving waters therefore based on PEEP results the first priority would be to reduce the toxic loading from industries 9 and 10. 

The first step in the analysis is to determine if zero degrees of freedom exist in any process unit. In this case, the analysis will be simplified because of the reduction in the number of equations requiring simultaneous solution. After analyzing each process unit, we then combine the equations to determine if the process contains zero degrees of freedom. When analyzing each unit separately, we will repeat some variables and equations. For example, in line 3, the composition and flow rate variables, and the mole fraction summation, are the same for the mixer exit stream and the reactor feed stream. Later, when we combine the various processing units to determine the process degrees of freedom, we will take the duplication of variables and equations into account. 

Once you are certain that all equations are independent and no equations are missing, then unspecify one of the variables. For example, unspecify the nitrogen concentration at the eonverter inlet, y3,e. Because is now unspecified, correct the degree of freedom analysis for both the mixer and converter. At the mixer and converter the number of variables increases by one as shown in Table 3.5.6. Thus, for the mixer F = 12 - 7 = 5 and for the converter F = 14 - 9 = 5. Because Equations 3.5.27 and 3.5.29 are not independent, the niunber of equations at the condenser-separator combination and the splitter are reduced by one, as shown in Table 3.5.6. Finally, because Z yi, is no longer vahd, it is not a repeated equation. Thus, the repeated equations in line 7 are now zero. The revised calculation for the degrees of freedom in Table 3.5.6 shows that the process degrees of freedom is now zero. 

The anomalous changes in the adsorption and thermodynamic characteristics of hydrocarbons on montmorillonite indicates explicitly that, at low surface coverage, the adsorption and separation of hydrocarbons take place in the surface micropores on the lateral faces of the mineral. With the increase in the amount of adsorbed modifier, the processing degree of the mineral packets by the organic substance also increases, resulting in the increase of the retention volume of hydrocarbons, and corresponding increase of Henry s... 

The number you are left with is the process degrees of freedom, and this is what will tell you if the process as a whole is overspecified, underspecified, or well-defined.
