could be added directly to the brine stream however if the pure article of commerce is added the addition rate must be slow to obtain the correct concentrations of crystal structure modifier in the brine stream the slow addition rate results in the crystal structure modifier having a long residence times in areas of high temperature leading in turn to thermal decomposition of the crystal structure modifier before it is even added to the brine stream therefore it is important to dilute the crystal structure to increase the rate of liquid addition at the crystal structure modifier addition points to prevent thermal decomposition of the crystal structure modifier before addition and prevent no more than 33 percent of the norms contained in the geothermal brine stream from precipitating during handling the water used to dilute the crystal structure modifier must have a low concentration of sulfate so 4 2 ion or the sulfate ion will combine with the crystal structure modifier before it contacts the brine stream in the figure the steam condensate is shown leading to each dilution point individually however if the first scale inhibitor step 92 the second scale inhibitor step 74 and third scale inhibitor step 80 all result in the same dilution of the same inhibitor then clearly the steam condensate could lead to one central dilution point and the diluted inhibitor would be distributed as shown in the flow scheme the flocculent must be.
