  1. 1. Evaluation of Excess Heat Driven Carbon Capture Integrated at a Swedish Pulp Mill

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Frida Nilsson; [2023]
    Keywords : CCS; BECCS; pulp and paper industry; pulp mill; excess heat; MEA; HPC; AMP; DMSO; chemical engineering; environmental engineering; Technology and Engineering;

    Abstract : As the atmospheric carbon dioxide keeps increasing, bioenergy with carbon capture and storage (BECCS) is getting increased attention as a measure to reduce the emissions of carbon dioxide. It is especially interesting in Sweden where the extensive paper and pulp industry constitutes point sources of biogenic carbon dioxide. READ MORE

  3. 2. Techno-economic evaluation of hydrochar via hydrothermal carbonisation of organicresidues

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Abdirahman Abdullahi; [2022]
    Keywords : Technoeconomic analysis; energy system modelling; HTC; hyrochar; system integration; OSMET;

    Abstract : This thesis has investigated the techno-economic feasibility of upgrading the sludge from a chemical pulp mill to hydrochar via hydrothermal carbonization (HTC). The intended use of the hydrochar was to replace fossil coal within metallurgical applications in the iron and steel industry. READ MORE

  4. 3. Techno-Economic Assessment of a Post-Combustion CO2 Capture Unit in SCA Östrand Pulp Mill

    University essay from KTH/Energiprocesser

    Author : Abhishek Subramani; [2022]
    Keywords : Bioenergy with Carbon Capture and Storage; Post-Combustion Capture; Monoethanol Amine; Chilled Ammonia; Techno-Economic Assessment;

    Abstract : The Paris Agreement has ambitious targets to limit the global warming below 1.5 °Cin the 21st century. This goal is reflected in the national climate targets, for example, Sweden aims to achieve net zero greenhouse gas emissions by 2045, and thereafter achieve negative emissions. READ MORE

  5. 4. Integrating Chemical Looping Gasification for Hydrogen Generation and CO2 Capture in Pulp Mills

    University essay from KTH/Energiprocesser

    Author : Matilda Pamér; [2022]
    Keywords : Carbon Capture and Storage; Bio-CCS; Chemical Looping Gasification; Pulp Mill; H2 generation; Process Analysis; Bio-CCS; CLG; Massabruk; H2 generering; Process Analys;

    Abstract : Utsläpp av CO2 till atmosfären bidrar till ökningen av globala temperaturer. Industrisektorn står för 20 % av utsläppen och utav dessa kommer 6 % från pappers- och massaindustrin. För att lyckas minska den globala temperaturhöjningen till under 1,5 °C hjälper det inte bara att minska utsläppen. Även negativa utsläpp måste genereras. READ MORE

  6. 5. Reducing cadmium emissions to water during removal of electrostatic precipitator ash : Investigating the effect of process parameters on the formation and precipitation of insoluble cadmium salts in water solutions

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Lukas Esperi; [2022]
    Keywords : cadmium; electrostatic precipitator ash; heavy metals; hydroxide precipitation; recovery boiler; elfilteraska; hydroxidfällning; kadmium; sodapanna; tungmetaller;

    Abstract : The removal of electrostatic precipitator (ESP) ash by solving the ash in water constitutes an environmental problem if heavy metals, such as cadmium, present in the ash remain in the outgoing effluent streams. The ESP ash solution is alkaline, meaning cadmium is present as the insoluble salt Cd(OH)2, cadmium hydroxide. READ MORE
