A method and apparatus for treating an exhaust or waste gas stream to remove pollutants from the gas stream using gas stabilization to allow the cleaned gas stream to be discharged directly to atmosphere. The apparatus includes at least three treatment stations for treating the gas stream in sequence, in which one of the treatment stations is a wet reactor containing a nucleating or precipitating liquids for removing the unwanted material as a solid and for oxygenating the gas stream to remove any residual unwanted material, and another of the treatment stations is a gas compressing stage for compressing the gas stream. The advantage of the method and apparatus is that the treated gas steam can be discharged directly to atmosphere with reduced amounts of pollutants.
An apparatus for carrying out a method of treating an exhaust gas stream to remove unwanted materials in order to clean the exhaust gas to be less polluting for discharge to atmosphere, using stabilization of the exhaust gas stream when in the apparatus, the apparatus comprising a first treatment station having an inlet through which the exhaust gas stream is introduced into the first treatment station for treatment therein, in which at least a first unwanted material is substantially removed from the exhaust gas stream substantially in the form of a solid to form an oxygenated gas stream, the first treatment station having an outlet for discharging the oxygenated gas stream to a second treatment station in which at least a second unwanted material is substantially removed from the oxygenated gas stream substantially in the form of a solid, to form a second treated gas stream, and a third treatment station for substantially compressing the second treated gas stream in the absence of atmospheric air to form a cleaned gas stream wherein the gas stream is passed sequentially through the first, second and third treatment stations in sequence to remove substantially the first and the second unwanted materials from the exhaust gas stream.
A method of treating an exhaust gas stream to remove unwanted material from the exhaust gas stream in order to clean the exhaust gas so that the cleaned exhaust gas is less polluting than prior to treatment by stabilizing the exhaust gas stream during the treatment, the treatment comprising the steps of directing the exhaust gas stream having at least a first unwanted material and a second unwanted material from a source of the exhaust gas stream to a first treatment station for initially treating the exhaust gas stream to form a first treated stream, said first treatment station being of a first capacity and containing at least a first liquid precipitating or nucleating agent for interaction with at least the first unwanted material of the exhaust gas stream to remove at least some of the at least first unwanted material from the exhaust gas stream to form the first initial treated stream, said first unwanted material being removed from the exhaust gas stream substantially in the form of a solid material, wherein oxygen removed from the first treated stream due to interaction with the first liquid precipitating or nucleating agent to form the substantially solid material is released into the first treated exhaust gas stream to form an oxygenated exhaust gas stream, discharging the oxygenated exhaust gas stream containing the oxygenated material from the first treatment station and introducing the discharged oxygenating exhaust gas stream into a second treatment station of a second capacity, said second capacity being less than the first capacity, said second treatment station containing at least a second liquid precipitating or nucleating agent for interaction with the oxygenated exhaust gas stream to remove at least some of the second unwanted material from the oxygenated exhaust gas stream substantially in the form of solid material so as to form a second treated gas stream, discharging the second treated gas stream from the second treatment station to a third treatment station for compressing the second treated gas stream to form a substantially cleaned gas stream, wherein the third treatment station is substantially isolated from atmosphere so as to substantially prevent atmospheric air from contacting the second treated exhaust gas stream in the third treatment station to interact with the treated gas stream, wherein the clean gas stream discharged from the third treatment station is substantially free of the first and of the second unwanted materials, and discharging the cleaned gas stream to atmosphere so that the cleaned gas stream is less polluting than the untreated exhaust gas stream.
