An ozonising module (1, 100) is disclosed having a housing (1a, 1b, 107) wherein an ozone generator assembly (3, 101) is accommodated, furthermore comprising at least an ozone sensor (4, 102) connected to a control unit (C) apt to control said ozone generator (3, 101) based on a time scheduling and a comparison between an ozone threshold concentration and a concentration signal from said ozone sensor (4, 102), ozone reduction means consisting of a filtering assembly with catalytic action (103) or a reducing assembly employing UV sources (113) through which an airflow is caused to flow by means of respective controlled ventilation means (103a).

An integrated waste gas treatment system includes an adsorption/desorption device that receives a waste gas that includes an organic compound and an organic nitrogen compound exhausted from a semiconductor manufacturing facility, where the adsorption/desorption device adsorbs the organic compound and the organic nitrogen compound and concentrates and desorbs the organic compound and the organic nitrogen compound, and a catalytic decomposition device disposed adjacent to the adsorption/desorption device, where the catalytic decomposition device includes a catalytic chamber that provides a gas passage through which a gas desorbed from the adsorption/desorption device flows and an oxidation-reduction catalyst disposed in the gas passage that removes the organic compound and the organic nitrogen compound from the desorbed gas. The organic compound and the organic nitrogen compound are subjected to an oxidation treatment by the oxidation-reduction catalyst, and nitrogen oxides generated by the oxidation treatment are removed by a selective reduction reaction.

An emissions clean-up process is provided to remove detrimental exhaust gases from a fossil fuel power plant and to produce and/or reclaim various useful commercial byproducts. The process includes mixing a blended liquid solution with a solubilizer in a mixing tank to create a chemical reaction therein to produce an ionic solid and an alkaline liquid solution. By mixing various blended solutions with desired solubilizers, alkaline liquids are produced which may be chemically combined to create other byproducts or sold commercially. Likewise, the alkaline liquids may be passed through a wet scrubber to create a byproduct that when chemically mixed with an acid creates desired byproducts. Other byproducts such as a sodium bicarbonate liquid solution exits the wet scrubber and is sold or used in the subject process to produce various other byproducts.

The present invention discloses an industrial solid waste incinerator and flue gas treatment apparatus, comprising a water-cooled feed hopper, a water-cooled grate and a chamber which are connected in sequence. A front arch, a rear arch and side walls which are formed of membrane water-cooled walls, are provided between the water-cooled grate and the chamber, and a dechlorination tower is arranged behind the chamber. Two sets of rear secondary air pipes, which comprise an upper set of rear secondary air pipes and a lower set of rear secondary air pipes, are arranged on the rear arch, and a dry desulfurization device is arranged between the two sets of rear secondary air pipes, so that the reaction medium and the flue gas are sufficiently disturbed and mixed, and stroke is extended.

A process for hydrotreating a feed stream comprising a biorenewable feedstock is disclosed. The process comprises hydrotreating the feed stream in the presence of a hydrotreating hydrogen stream and a hydrotreating catalyst to provide a hydrotreated stream. The hydrotreated stream is separated into a hydrotreated liquid stream and a hydrotreated gas stream. The hydrotreated liquid stream is subjected to stripping to provide a stripper off-gas stream. At least a portion of the stripper off-gas stream is contacted with a caustic stream to provide a sulfur-lean gas stream and a sulfur-rich caustic stream. The sulfur-rich caustic stream is further treated to provide a treated gas stream.
