  3. 2. Water blow out phenomena inside a heavy truck silencer

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Rohit Suram Venkata Subramaniyam; [2020]
    Keywords : Water blow out in after treatment devices; Dew point strategy; Exhaust after treatment system; NOx sensors; Water formation in the exhaust; Vatten blåser in efter behandlingsanordningar; Daggpunktsstrategi; Avgas efter behandlingssystem; NOx-sensorer; Vattenbildning i avgaserna;

    Abstract : NOx sensors have become salient components in the development of efficient exhaust after treatment system for heavy duty vehicles in the past few years. When the accumulated water inside the silencer splashes on to the NOx sensor, it can cause permanent cracks in the sensor. READ MORE

  4. 3. Development of a GC Method for the Quantification of Short Chain Carboxylic Acids in Aqueous Solution

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Anton Åkervall; [2020]
    Keywords : DAI-GC-FID; Direct Aqueous Injection; Gas Chromatography; Flame Ionization Detector; SCFA; Short Chain Fatty Acids; Formic Acid; Acetic Acid; Lactic Acid; EGR; Exhaust Gas Recirculation; CAC; Charged Air Cooler; FFD; Fractional Factorial Design;

    Abstract : Petroleum powered vehicles emit volatile organic compounds (VOCs) through combustion that contributes to the pollution of the environment. A technique in the 1970s was developed to decrease these emissions, especially for nitrogen oxides (NOx) and sulphuric oxides (SOx) which is called exhaust gas recirculation (EGR). READ MORE

  5. 4. Life cycle assessment of coal based direct-reduced iron production in India

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : SABARISH ELANGO; [2020]
    Keywords : ;

    Abstract : The production of iron through direct reduction (Direct-Reduced Iron; DRI) involves the use of natural gas or coal to reduce iron ore to iron through carbothermic reactions at a temperature below its melting point, negating the need for a blast furnace as otherwise required. In India, around 25% of iron is produced through direct reduction. READ MORE

  6. 5. CFD Simulation of Urea Evaporation in STAR-CCM+

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Oscar Ottosson; [2019]
