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

    University essay from KTH/Kemiteknik

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

    Abstract : 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). READ MORE

  3. 2. Identifying risks of AdBlue spray on stainless steel surfaces

    University essay from KTH/Kemiteknik

    Author : Evelina Tvinne Flyg; [2021]
    Keywords : Urea; Stainless steel; SCR; Deposit; Corrosion; Urea; rostfritt stål; SCR; Avlagring; Korrosion;

    Abstract : Utsläppskontroll, reglerad av allt strängare lagstiftning, ställer höga krav på utvecklingen av noggranna efterbehandlingssystem för avgaser. När det gäller utsläpp från dieselmotorer utgör NOx-minskning en av de största utmaningarna. För tunga fordon tacklas denna utmaning ofta genom ett SCR-system. READ MORE

  4. 3. CFD Simulation of Urea Evaporation in STAR-CCM+

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Oscar Ottosson; [2019]
    Keywords : Urea; AdBlue; SCR; Solid Deposit; NOx; nitrogen oxides; CFD; speedup; spray simulation; UWS; diesel after-treatment; STAR-CCM ; AVL Fire; Scania; Sweden; NXPS; LiU; DOE; Urea; AdBlue; SCR; Klump; NOx; kvävedioxider CFD; uppsnabbning; spray simulering; UWS; efterbehandling av diesel-motor; STAR-CCM ; AVL Fire; Scania; Sverige; NXPS; LiU; DOE;

    Abstract : Diesel engines produce large amounts of nitrogen oxides (NOX) while running. Nitrogen oxides are highly toxic and also contribute towards the formation of tropospheric ozone. READ MORE

  5. 4. Methods of calibration for different functions of a SCR-system

    University essay from KTH/Reglerteknik

    Author : Ahmed Elfeky; [2018]
    Keywords : ;

    Abstract : The goal of this research is to try and compare different methods ofcalibration in order to tune the parameters of the pumping and tankheater monitoring functions of the AdBlue Delivery Module of a SelectiveCatalytic Reduction (SCR) system. The goal of the SCR systemis to reduce the emission of NOx gases, which are considered as greenhousegases. READ MORE

  6. 5. CFD-simulations of urea-waterspray in an after-treatment systemusing Star-CCM+

    University essay from KTH/Mekanik

    Author : Emelie Trigell; [2018]
    Keywords : after-treatment systems; selective catalytic reaction SCR ; AdBlue; multiphase flow; multi-component liquid; Unsteady Reynolds Average Navier Stokes RANS ; wall film formation; solid deposits; efterbehandlingssystem; selektiva katalytiska reaktioner; AdBlue; flerfasstr ¨ommning; flerkomponentvätska; Unsteady Reynolds Average Navier Stokes; väggfilm; avlagringar;

    Abstract : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. READ MORE
