    Abstract: The present invention discloses an ozone generator with reduced NOx comprising an air stream generating means; a drying means; an electrical field generating unit; a high-voltage generating means; and a cooling means. The flow velocity of the air stream in the ozone generating area can be increased by means of the air stream generating means up to 700 s.c.c.m, The temperature in the ozone generating area can be lowered by means of the cooling system to lower than 10null C. By means of the above, the amount of NOx produced by the disclosed ozone generator can be reduced substantially.

    Abstract: Ozonizer (10) which supplies a feed gas to ozone generating cell (11) under application of a high voltage and which delivers an ozone gas through an ozone gas transport path (consisting of pipes (14) and (15)) as it has been generated in said ozone generating cell (11) is characterized in that the ozone gas transport path is furnished with means for removing at least one of NOx, HF and SOx (in the drawings, the means is for removing NOx) and that the ozone gas from the ozone generating cell (11) is passed through said removing means, whereby at least one of NOx, HF and SOx in said ozone gas is removed before it is delivered to a subsequent stage. The product ozone is not contaminated with Cr compounds at all or insufficiently contaminated to cause any practical problems in the fabrication of highly integrated semiconductor devices.Alternatively, ozonizer (10) which comprises an ozone generating cell (11) having an inlet (8) for supplying a feed gas, high voltage applying means (35) and an outlet (29) for discharging the ozone generated, and ozone delivery paths (30) and (31) for delivering the generated ozone is characterized in that oxygen (1) supplemented with 10-20 vol % of carbon dioxide and/or carbon monoxide (2) is used as the feed gas. The thus produced ozone is significantly low in the level of Cr compounds and, hence, can suitably be used in the formation of metal oxides, in particular, silicon oxide.

    Abstract: A process for conditioning an ozone gas recycle stream in an ozone pulp bleaching process, wherein the level of carbon dioxide in the recycle stream is controlled to allow full capacity operation of the ozone generator. Carbon dioxide concentration is identified over the relevant operational ranges and maximum concentration is identified for full capacity/optimum efficiency operation. Specific methods are described for controlling carbon dioxide concentration including purging a portion of the recycle stream, counter-current scrubbing of the recycle stream with an alkaline solution and passing the recycle stream through an adsorbent material. Contaminants entering the system also may be reduced by directing the purged recycle stream, which is relatively oxygen rich, into the dewatering press where pulp consistency is increased. In this manner nitrogen surrounding the pulp is displaced by oxygen and thus, does not enter the bleaching/ozone system with the pulp.

    Abstract: The ozonization installation comprises a group of n ozonizers supplied with energy by a common source in a successive alternating voltage wave train mode, the application of the wave trains being controlled by a control device. The latter produces initiating signals which selectively enable the passage of the electric energy in the form of wave trains coming from the common source to the ozonizer. The installation comprises a servo system chain comprising devices for controlling the duration of the initiating signals by means of a set signal, having regard to the total ozonization produced by the n ozonizers. This duration corresponds to that of each successive wave train. Synchronization devices are provided for connecting the common energy source to solely one ozonizer at a time.

    Abstract: Disclosed are an ozone generator and an ozone generating method for highly efficiently generating ozone at a high concentration wherein there is used a raw material gas mainly containing an oxygen gas to which no nitrogen is added, thereby producing no NOx by- product. Ozone is generated by supplying a raw material gas (25) mainly containing an oxygen gas which is free from nitrogen into an ozone generator (300), producing at least a discharge light having a wavelength of 428-620 nm by applying an alternating current voltage thereto, arranging a photocatalyst substance containing a photocatalyst substance (303) having a band gap of 2.0-2.9 eV on an electrode or dielectric body in a discharge area, and maintaining the gas pressure at 0.1-0.4 MPa.
