Centralizing the handling and manipulating of vaporization medium to a single subsystem that supplies multiple ammonia vaporizers allows for efficient and effective production of a corresponding vaporized ammonia stream containing a controlled quantity of ammonia. These vaporized ammonia streams can then be used in conjunction with ammonia-consuming devices to reduce NOx in NOx-containing exhaust streams from multiple furnaces.

Provided is a carbon dioxide capturing apparatus comprising: a reaction tower including a carbon dioxide adsorption unit or a carbon dioxide absorption unit which adsorbs or absorbs carbon dioxide from exhaust gas; desorption tower connected to the reaction tower and including an adsorbent heating unit for heating an adsorbent circulating inside or an absorbent heating unit for heating an absorbent circulating inside; an adsorbent or absorbent which circulates in the reaction tower and the desorption tower and alternately adsorbs and desorbs carbon dioxide or alternately absorbs and desorbs carbon dioxide; and a heat exchange unit which desorbs carbon dioxide from the adsorbent on which carbon dioxide is adsorbed or the absorbent in which carbon dioxide is absorbed, through heat exchange between the adsorbent on which carbon dioxide is adsorbed and the heated adsorbent, or between the absorbent in which carbon dioxide is absorbed and the heated absorbent, wherein the adsorbent on which carbon dioxide is adsorbed and the heated adsorbent, or the absorbent in which carbon dioxide is absorbed and the heated absorbent are transferred in a co-current flow manner.

The invention relates to a method for purifying exhaust gas and for regenerating an oxidation catalytic converter, comprising treating the exhaust gas in an oxidation catalytic converter, which comprises a catalytically active material, which contains at least one noble metal and/or at least one base transition metal, wherein the oxidation catalytic converter is operated continuously or at times at a temperature that causes the oxidation of soot particles and/or carbon particles, and/or wherein the oxidation catalytic converter is periodically heated to a temperature that causes the oxidation of soot particles and/or carbon particles.

The present disclosure relates to methods for processing plastic waste pyrolysis gas, such as methods wherein clogging of the systems used in the method is avoided or at least alleviated.

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.

A catalyst comprises a mixture of 95% vol. to 30% vol. of an activated carbon catalyst and from 5% vol. to 70% vol. of a filler material as well as a configuration of such a catalyst for the removal of SO.sub.2, heavy metals and/or dioxins form waste gas and liquids.
