摘要： A thermal oxidizer employing an oxidation mixer, an oxidation chamber, a retention chamber and a heat dissipater forming a fluid flow path for thermal oxidation of a waste gas. In operation, the oxidation mixer facilitates a combustible mixture of the waste gas and an oxidant into an combustible waste gas stream, the oxidation chamber facilitates a primary combustion reaction of the combustible waste gas stream into an oxygenated waste gas stream, the retention chamber facilitates a secondary combustion reaction of the oxygenated waste gas stream into oxidized gases and the heat dissipator reduces the temperature of the flow of oxidized gases within the heat dissipator, which is communicated to a greenhouse gas processor that extracts greenhouse gas(es) from the vaporized oxidized gases. The greenhouse gas processor may condensate the greenhouse gas(es), acid neutralize the condensation of the greenhouse gas(es), and capture the acid neutralization of the condensation of the greenhouse gas(es).

摘要： The present invention relates to a process and an apparatus for utilizing fossil energy with low carbon emissions, which belongs to a technical field of clean energy and climate mitigation. The present invention is applicable for utilizing fossil, biomass and other carbon-containing fuels in coastal and marine areas to produce clean energy with low carbon emissions to atmosphere and low cost. The process comprises the main steps of carrying out the oxygen enriched combustion and using seawater to scrub the flue gas once to realize carbon capture, and the scrubbing water is recovered to a water quality in accordance with legal requirements and then is discharged into the ocean to realize carbon storage of ocean natural alkalinity, so that the resources of carbon sink and carbon pool in natural ocean are used to reduce greenhouse gases in the atmosphere in a safe and environment-friendly form.

摘要： The disclosure relates generally to reducing mercury emissions from a coal power plant. Specifically, a method for treating a gas stream containing mercury is provided that includes injecting a mercury oxidant or absorbent and a carrying agent into a gas stream that was produced by heating or burning a carbonaceous fuel comprising mercury. The carrying agent vaporizes after being injected into the gas stream. The mercury oxidant or absorbent and a carrying agent may be injected before passing the gas stream into a gas scrubber.

摘要： The present invention relates to an air purification apparatus for a coal-fired electric power plant, and more specifically to an air purification apparatus for a coal-fired electric power plant, which, first, can filter out wastes of contaminated smoke by using limewater, which, second, can filter out fine dust and carbon dioxide included in the smoke, which, third, can convert waste gas including carbon monoxide in a state in which only smoke remains into carbon dioxide by reacting oxygen with the waste gas and purify the smoke into clean air by allowing a sodium hydroxide solution to absorb the carbon dioxide, and which, fourth, can eliminate humidity from the clean air by passing the clean air through a moisture condenser a plurality of times and discharge clean air in a pure smoke state from the power plant.

摘要： A method for controlling mercury release, emission and/or re-emission levels in a treated flue gas and a seawater effluent waste stream through control of a sulphite concentration within a seawater scrubber system is disclosed. One method for controlling mercury release, emission and re-emission levels through control of sulphite concentration is to measure the sulphite concentration of seawater entering a seawater scrubber system and comparing the same to a predetermined sulphite concentration value. If the comparison reveals the measured sulphite concentration is above the predetermined sulphite concentration values, the amount of fresh seawater and/or oxidation air supplied to the seawater scrubber system is increased. If the comparison reveals the measured sulphite concentration is below the predetermined sulphite concentration values, the amount of fresh seawater and oxidation air supplied to the seawater scrubber system is decreased.
