Chlorine dioxide production relationship

From the chlorine/chlorine dioxide production relationship, 0.53 wt of chlorine produces 1 wt of chlorine dioxide, calculator c4-13. 

Expressing the weight relationship in this way allows the sodium chlorite consumption to he calculated for any concentration or for any chlorine dioxide production amount. Also, any weight units can he used as long as all the units used are identical. 

For the steady-state situation, chlorine dioxide emissions are measured when altering process variables such as concentration, temperature and production capacity. These measurements result in a number of relationships, plotted in Figs 25.2 and 25.3, with respect to the hypochlorite installation. 

It is important to follow equipment manufacturer s instructions to generate chlorine dioxide efficiently. Adjustments to chlorine and sodium chlorite feed may be necessary to optimize production and minimize forming unwanted by-products (chlorate, chlorite, or excess chlorine). The high-yield production of chlorine dioxide depends on the relationship of chlorine to sodium chlorite, pH, and other factors. Precise and accurate control of all variables is necessary to produce the highest-purity product and to minimize undesirable byproducts. 

These systems generate chlorine dioxide gas so the dosage calculations are the same as pure gas systems (c4-l and c4-2). Chlorine dosage produces chlorine dioxide according to the theoretical relationship above (0.53 wt units of chlorine produce 1 wt unit of chlorine dioxide), but a maximum production concentration of about 8 percent.
