Some Other Design Factors to be Considered in Analysis... 

For economy in construction and operation of plants for handling saline water, particular attention must be paid to corrosion factors. Steel can be used in many applications, if it is protected by the use of coatings or is given cathodic protection. Allowance also can be made in the design for the corrosion of steel. If it does not conflict with other design factors, incoming sea water should be deaerated to control steel corrosion. Corrosion inhibitors and chemical treatment may be employed to reduce the attack, but frequently this method is too costly.

Figure 7. That is, to enhanee the initial power performance of our hypothetieal electrode, the surfaee design of active materials to elevate the electrochemical activity must come before all other design of the cell constituents. On the other hand, when the power performance must not drop off significantly in the later stage of discharging time and level off throughout the whole discharging time, the bulk design of active materials to promote solid-state diffusion takes precedence over all other design factors.

Overhead level control may be calculated simply by the method of Chapter 16, Section 3, but base level control by boilup is very difficult. It is normally used only when the average bottom-produa flow is very small. The characteristic time constant th should be at least 15 minutes and other design factors should be as indicated in Chapter 16, Section 7. In most cases base level control by boilup requires a dynamic analysis, and perhaps supplementary plant tests. If steam flow is measured with an orifice, a square root extractor should be used.
