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.

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.

Abstract: A method for the continuous production of ozone and recovery of oxygen in a purge cycle adsorption process having four adsorbent beds. The method has the steps of feeding a mixture of ozone and oxygen to a first and second adsorbent bed wherein the first and the second adsorbent bed adsorb ozone and allow oxygen to pass through; recovering the oxygen from the first bed; feeding the oxygen from the second bed to a fourth adsorbent bed, wherein ozone is desorbed from the fourth bed; feeding clean dry air through a valve to the third adsorbent bed, and measuring the flow rate of the clean dry air through the valve, comparing this flow rate to a pre-calculated value and adjusting the flow rate of the clean dry air to equal the pre-calculated value; desorbing ozone from the third bed; and recovering ozone from the third bed and the fourth bed.

Abstract: A method for the partial removal of contaminants such as nitrogen oxides from a process gas stream is described. The process gas stream is separated into at least two process gas streams by means of a partition, baffle, damper or other device. Ozone is fed into contact with at least one of the separated process gas streams to oxidize the contaminants therein and the at least one of the process gas streams contacted by ozone is fed to a scrubber for removal of the oxidized contaminants from the gas streams. The separation is proportional to the percentage removal of contaminants desired.

Abstract: A method for separating ozone from a mixture of oxygen and ozone by feeding the mixture to at least one adsorbent bed containing an adsorbent material for adsorbing ozone. The adsorbent bed can be one of four adsorbent beds in a continuous adsorption cycle for producing ozone recycling the non-adsorbed oxygen together with make-up oxygen to the ozone generator or using it as a purge gas. An external purge gas is used to desorb the ozone to the customer process. With four beds present, for most of the time, two beds are in adsorption mode while the other two beds are in regeneration/production mode.

Abstract: A method and apparatus for increasing the concentration of oxygen in the reaction medium present in the oxidation reactor. A volume of aqueous medium from the oxidation reactor is removed and pressurized and oxygen is added to it. The oxygen-rich volume of aqueous medium is then reintroduced into the oxidation reactor at an increased pressure to ensure adequate mixing with the aqueous medium having a lower content of oxygen.
