  1. 1. Fritidsrepertoarer bland äldre personer i Västerbotten : En tvärsittsstudie baserat på material från 2021 ur Gerontoligisk regional Databas

    Kandidat-uppsats, Umeå universitet/Avdelningen för arbetsterapi

    Författare :Mea Kulla; Ornella Nitunga; [2024]
    Nyckelord :fritidsaktivitet; särskilt boende; äldre kvinnor och män; ar-betsterapi; GERDA;

    Sammanfattning : Individens vanor och roller förändras över tid och pensionering kan innebära alltmer fritid. Fritidsaktiviteter har goda effekter på hälsan, helst när individen engagerar sig i aktiviteter som hen vill utföra. LÄS MER

  3. 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

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

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

    Sammanfattning : 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.

  4. 3. The Commissioning of a Pixelated Charge-particle Detector : for High-sensitivity Measurements of Hydrogen

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Joacim Stenlund; Aram Himelius; [2023]
    Nyckelord :;

    Sammanfattning : The Tandem Laboratory at Uppsala University, a national research infrastructure forworld-leading materials analysis, has a long history of performing hydrogen measurementusing NRA (Nuclear Reaction Analysis). This project intents to diversify the infras-tructure for hydrogen measurement by investigating the feasibility of an advanced ERCS(Elastic Recoil Coincidence Scattering) system, enabling finer detection limits.

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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

    Sammanfattning : 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. LÄS MER

  7. 5. Techno-economic Assessment of Carbon Capture from Low Concentration Streams

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Prithvi Kiran Joshi; [2023]
    Nyckelord :Carbon capture; industrial emissions; low concentration; MEA; Benfield; absorption; Immobilised Amine; adsorption; Kolavskiljning; industriella utsläpp; låg koncentration; MEA; Benfield; Absorption; Immobiliserad amin; Adsorption vi;

    Sammanfattning : Investments in carbon capture from industrial emissions have been on the rise in recent years, having reached over $200 million in 2021 as compared to 2015’s $13 million. The Paris Agreement, signed by 196 parties globally in 2015, is purported to be the primary driver for this, with its ambitious goal of limiting global surface temperature rise to 1. LÄS MER
