  1. 1. A VVER1000 primary side model in Apros

    University essay from KTH/Fysik

    Author : Karl-Edvin Strand; [2023]
    Keywords : Apros; VVER1000; PWR; Modelling; HPIS; Boron acid; Apros; VVER1000; PWR; Modellering; HPIS; Borsyra;

    Abstract : Nuclear power plants generate electricity by means of splitting atoms. The basic safety requirements and objectives are to protect the people, society, and the environment from radiological accidents, limit harmful effects of ionizing radiation during operation and take all reasonable practical steps to prevent radiological accidents.

  3. 2. Lignin modification for higher reactivity towards epoxides

    University essay from KTH/Fiber- och polymerteknologi

    Author : Filip Rynkiewicz; [2023]
    Keywords : Lignin; modification; reactivity; epoxide; oxidation; Lignin; modifikation; reaktivitet; epoxid; oxidation;

    Abstract : Fem metoder har använts för att modifiera barrvedslignin med syftet att öka reaktiviteten av ligninet mot epoxidgrupper. Ligninprover analyserades med NMR och FTIR medan reaktivitet var mätt genom reometri. Metoder som ökade mängden karboxylsyragrupper på ligninet minskade ligninets reaktivitet. READ MORE

  4. 3. Particulate matter analysis from engine outlet in heavy-duty diesel vehicles : A study of soot reactivity, morphology and ash-to-soot ratio from the outlet of 6-cylinder and 8-cylinder diesel engines.

    University essay from KTH/Kemiteknik

    Author : Tayisiya Vlasenko; [2023]
    Keywords : Diesel engine; particulate matter; kinetics; soot; heavy-duty vehicles; Dieselmotor; partiklar; kinetik; sot; tunga fordon;

    Abstract : De ökande luftföroreningarna i Europa är ett allvarligt miljöproblem, och vägtransporterna är en av de största orsakerna till detta. För att ta itu med detta problem och uppfylla nya utsläppskrav måste efterbehandlingssystemen för avgaser förbättras. READ MORE

  5. 4. Desulphurisation of cement flue gases

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ellen Sjöstrand; [2023]
    Keywords : Flue Gas Desulphurisation; FGD; gypsum; cement;

    Abstract : Flue gas desulphurisation (FGD) is a crucial method to minimise the SO2 emissions from industrial processes. The FGD system utilise an alkaline sorbent to remove SO2 from the flue gases. Calcium in form of limestone is a commonly used sorbent where gypsum is produced asa by-product. READ MORE

  6. 5. Unspecific interactions in different batch variations of agarose based base matrices at different NaCl concentrations.

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Kejvan Ghofranpanah; [2022]
    Keywords : Lysozyme; hydrophobicity; size exclusion chromatography; NaCl concentrations; isocratic elution; Lysozym; hydrofobicitet; size exclusion chromatography; NaCl-koncentrationer; isokratisk eluering;

    Abstract : Size exclusion chromatography (SEC) separates molecules based on their actual size rather than their molecular weight. This indicates that the smaller a molecule is, the longer it will be held in the column since it can penetrate the pores more effectively than a bigger molecule, resulting in a longer retention time, whereas the larger molecule has a shorter retention time.
