  1. 1. Acoustic Characterization of Catalyst

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Surachit Dokson; [2023]
    Nyckelord :;

    Sammanfattning : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. LÄS MER

  3. 2. Water emissions from fuel cell-powered construction equipment : Quantifying liquid water and water vapor emissions for sustainable construction equipment

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Roni Bulut; Patric Söderberg; [2023]
    Nyckelord :PEM fuel cell; Simulink; Simscape; construction equipment; exhaust water; liquid water; vapor water; performance;

    Sammanfattning : The construction sector is responsible for 20% of Greenhouse Gas (GHG) emissions, of whichdiesel-powered construction equipment are large contributors. Currently there are many ongoing Fuel Cell (FC) powered construction equipment projects as it is seen as an attractiveoption to power the futures zero-emission heavy-duty machines. LÄS MER

  4. 3. INVESTIGATING THE TOXIC AND ACIDIFYING EFFECT OF SCRUBBER EFFLUENT ON STRONGYLOCENTROTUS DROEBACHIENSIS LARVAE

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Ida Vartia; [2022-09-28]
    Nyckelord :;

    Sammanfattning : To meet the new environmental requirements of reduced sulfur emissions from ships, many shipowners have installed an open-loop scrubber to clean the exhaust. In this scrubbing process, seawater is pumped from the ocean and combined with the emission gas, creating an acidic and toxic effluent that is directly discharged into the ocean, potentially damaging the marine environment.

  5. 4. Investigation into Urea Deposit Risk by varying parameters in the control system related to urea evaporation

    Master-uppsats, KTH/Kemiteknik

    Författare :Anna Sandström; [2022]
    Nyckelord :Urea Deposits; Urea Decomposition; Selective Catalytic Reduction; Urea Dosing; Ureautfällning; Ureanedbrytning; Selektiv katalytisk reduktion; Ureadosering;

    Sammanfattning : I och med nuvarande och kommande lagkrav för utsläpp från tunga lastbilar finns en efterfrågan på utvecklade strategier för utsläppsminskning. För att kontrollera utsläppen av kväveoxider (NOx) används katalytisk omvandling med AdBlue (vätskeblandning av urea och vatten). LÄS MER

  7. 5. The Potential of Electrification in reducing Emissions from Passenger Cars in Stockholm County by 2030 : A Modeling Study of the Potential of Plug-In Hybrids and All-Electric Cars in reducing Greenhouse Gas Emissions and Air Pollution

    Master-uppsats, KTH/Transport och systemanalys

    Författare :Arvid Hedbäck; [2021]
    Nyckelord :electric cars; electrification; Stockholm; 2030; modeling; Scaper; HBEFA; CO2; air pollution; nitrogen oxides; NOx; hydrocarbons; HC; particulate matter; PM10; PM2.5;

    Sammanfattning : This study examines the potential of electrification in reducing greenhouse gas emissions and air pollution from passenger cars in a short- to mid-term time perspective. Using Stockholm County as a case study, this has been done in a three-step process by modeling the relative change in emissions between 2019 and 2030. LÄS MER
