Feed of Gases-Calculations and Examples

Liquefied gases under pressure are commonly fed as gases when used in water treatment processes. Calculations are necessary to determine the correct settings to dehver the desired amount of chemical to the water flow. Also, it is important to monitor the chemical use to anticipate when to order the delivery of more supplies. [Pg.39]

Consistent units of measure used in the calculation formulas (calculators) are a must. For example, each calculator is either in US or SI (metric) units (Appendix B). To use these calculators, it may be necessary to convert the units of measure to match those in the formula (Tables 4-1 and 4-2). The calculators here are simplified, often with the constants already incorporating the conversion factors. The derivation of the simplified calculators is given in Appendix D. Chemical feed calculators are provided for the most common treatment situations. Combinations of these calculators may he needed for other treatment systems. [Pg.39]

Example 12.5 For ideal gases at 25°C = 298 K, the calculated equilibrium constant (based on Table A.8) for Reaction 12.Z is K=29.6. If water, ethylene, and ethanol are in equilibrium at 1 bar and 298 K with the same feed ratios as in Example 12.4, what are the concentrations of reactants and products ... [Pg.226]
