A chloride dioxide generation system made efficient by the use of a
minimum number of seals and the use of a sophisticated computerized
control system with the chlorine dioxide generation system comprising a)
multiple PID loop control, b) a touch screen interface (HMI), c)
automatic flow control of chemical precursors, d) a process controller,
e) a minimum number of seals, f) a seal-less vacuum eductor, g) a unit
design of the ejector; seal-less tubing connector and seal-less manual
flowmeters, h) a vacuum eductor to be used with gas supply and other
chemical feeds, i) a mass dispersion chlorine flowmeter to accurately
supply amount of chlorine gas, j) an optical chlorine dioxide analyzer
looped to the process controller and k) an automatic efficiency control
screen.
