  2. 1. Ammonia-Based Post-Combustion Capture of Carbon Dioxide

    Author : Henrik Jilvero; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCS; Ammonia; Post-combustion;

    Abstract : Post-combustion capture of carbon dioxide is one of the measures to reduce emissions of carbon dioxide from large point source emitters. In post-combustion capture the carbon dioxide is absorbed from the flue gas by means of a liquid absorbent. READ MORE

  4. 2. Post-Combustion CO2 Capture in Kraft Pulp Mills - Technical, Economic and System Aspects

    Author : Erik Hektor; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical absorption; Excess heat; Post-combustion; Chilled ammonia; Process integration; Mono-ethanolamine; Pulp and paper; CO2 capture;

    Abstract : As a result of increasing concerns about climate change, there is considerable research and activities around CO2 capture and storage. In this thesis it is studied what role the pulp and paper industry can play in mitigating climate change through CO2 capture and storage. READ MORE

  5. 3. Numerical Study of the Gas Flow and Heat Transfer during Electromagnetic Stirring and Post Combustion in EAFs

    Author : Niloofar Arzpeyma; Pär Jönsson; Dongyuan Sheng; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMS; EAF; post combustion; heat transfer; duct system;

    Abstract : The effect of electromagnetic stirring on scrap melting and post combustion in two different electric arc furnaces (EAFs) have been studied using numerical modelling. The effect of electromagnetic stirring on melting of a piece of scrap located at the eccentric bottom tapping (EBT) region of an EAF has been studied. READ MORE

  6. 4. Modeling of post-combustion carbon capture in power plants and process industries - partial capture and load following conditions

    Author : Stefanìa Òsk Gardarsdòttir; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post-combustion; MEA; ammonia; dynamic modelling; chemical absorption; industrial sources;

    Abstract : Carbon capture and storage (CCS) is recognized as a potent technology for the mitigation of global warming, since it can significantly reduce CO2 emission from large point source emitters. Post-combustion CO2 capture using chemical absorption is a versatile end-of-pipe technology that can be implemented at all point sources of CO2, such as a power production facility or industrial plant.

  7. 5. Modeling of Gas Flows in Steelmaking Decarburization Processes

    Author : Zhili Jack Song; Pär Jönsson; Seppo Louhenkilpi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOD; nozzle; jet; vacuum; BOF; LD; AOD; post combustion; flue; CFD;

    Abstract : The purpose of the current study is to increase the understanding of different steelmaking processes at the decarburization stages by use of mathematical modeling. More specifically, two De-Laval nozzles from a VOD (Vaccum Oxygen Decarburization) process, which is used for producing stainless steels with ultra-low carbon grades, was investigated for different vessel pressures.
