Abstract
A method for producing ozone is disclosed. The ozone is separated by an adsorbent separation system from a mixture of oxygen and ozone. The adsorbent separation system operates by adsorbing ozone at higher pressures, then desorbing the ozone at normal pressures. Increased ozone concentrations result from these steps while the oxygen component can be recovered and used in producing the mixture of oxygen and ozone.
Claims11
A method for producing ozone from an oxygen and ozone mixture, comprising:
- separating ozone present in an oxygen and ozone mixture in concentrations ranging from 6% to 12% by adsorbing the ozone in an adsorbent separation system at a higher pressure, wherein the ozone adsorbed in an adsorbent is in equilibrium with ozone at the partial pressure of ozone in the oxygen and ozone mixture;
- introducing a weakly adsorbed gas into the adsorption separation system;
- contacting the weakly adsorbed gas with the adsorbent at a lower pressure than the higher pressure, thereby desorbing ozone at a partial pressure that is the same as that during adsorption, to thereby produce an ozone stream at a higher concentration than that present in the adsorption;
- and
- transporting the desorbed ozone with the weakly adsorbed gas from the adsorption separation system.
