Method for controlling an ozone generating machine

A method for producing ozone in an ozone generating machine (OGM) comprising at least two electrodes (E1, E2) separated by an ozonizing gap (OG) and a dielectric layer, and located in an ozone generator (OzG) comprising at least a gas inlet (O2IN) for receiving a feed gas containing dioxygen, and a gas outlet (O3OUT) for exhausting gas comprising ozone, the method comprising the steps of:

• supplying the feed gas containing dioxygen at the gas inlet (O2IN) of the ozone generator (OzG), at a first feed gas flow rate and first feed gas pressure,
• supplying an alternating electric current to said at least two electrodes (E1, E2) of the ozone generator (OzG) so as to create electric discharges in the ozonizing gap (OG), to generate a given amount of ozone at the gas outlet (O3OUT) of the ozone generator (OzG),
• adjusting an electric current power density and at least one process parameter selected from a plurality of process parameters comprising:
• (i) feed gas flow, (ii) frequency of the alternating electric current, (iii) voltage of the alternating electric current, or (iv) cooling temperature of the ozone generator (OzG), to adjust the amount of generated ozone at the gas outlet (O3OUT) of the ozone generator (OzG),
• characterized in that the method comprises, during ozone production, the steps of:
• monitoring electric power and the at least one process parameter,
• adjusting the first feed gas pressure to a second feed gas pressure in response to the adjustment of at least one process parameter.
