  1. 1. Gas Chromatographic Method Development for Analysis of Samples from a Carbon Capture Pilot Plant

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : David Wedin; [2024]
    Keywords : Carbon Capture and Storage; CCS; AMP DMSO; Gas Chromatography; amine absorption; analysis method development; Chemical Engineering; Chemistry;

    Abstract : In response to the escalating threat of climate change, carbon capture and storage have gained increasing attention as an important component in mitigating the global carbon dioxide emissions. Substantial research efforts have focused on enhancing the energy efficiency and availability of these technologies. READ MORE

  2. 2. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Tanmmay Rout; [2023]
    Keywords : Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

    Abstract : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

  3. 3. Soil Organic Carbon in Boreal Agricultural Soil : Tillage interruption and its effect on Soil Organic Carbon

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Hilda Alfredsson; [2023]
    Keywords : soil organic carbon; agriculture; tillage interruption; carbon sequestration;

    Abstract : Farmers have been disrupting the carbon cycle ever since humans started converting forests to agricultural lands. But are there farming practices that can be applied to increase the carbon storage in the soil and subsequently counteract increasing carbon dioxide levels in the atmosphere? In this study I investigate if soil organic matter (SOM) and soil organic carbon (SOC) change with longer interruption between tillage events. READ MORE

  4. 4. 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

  5. 5. Predicting room occupancy based on carbon dioxide concentration levels : And potential energy-saving use cases in HVAC (heating, ventilation and air conditioning) control systems.

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Elias Eliasson Schuhmacher; Markus Ledung; [2023]
    Keywords : ;

    Abstract : This thesis aims to explore the possibilities of recording room occupancy based on measured CO2 (carbon dioxide) concentration levels, and potential energy-saving uses in HVAC (heating, ventilation and air conditioning) - control systems. Furthermore, this thesis specifically aims to use unsupervised machine learning methods, which removes the need for generating correct occupancy labels and training the models before deploying them.
