  • Recovery of oxygen used in ozone production
    Patent number: 10730004
    Abstract: A method of continuous ozone production using a system of four absorbent beds to separate an ozone and oxygen gas mixture generated in an ozone generator. The beds are operated according to an offset sequence of cycles. Oxygen passing through the beds is at least partially recycled for use in further ozone generation. The concentration of oxygen in the ozone product can be reduced using the system to make it suitable for use in fine chemical applications.
    Type: Grant
