    Abstract : Corrosion has posed a significant challenge within the maritime sector for numerousyears. In the 21st century, bolstering the corrosion resistance of alloys, particularlyaluminum alloys, has become paramount. Aluminum alloys find widespread use inpropulsion systems, boat hulls, and cargo vessels. READ MORE

  3. 2. Reactor Chemistry in LWR SMRs : Determination of the rate constant for the reaction between boric acid and hydroxyl radicals

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Fredrik Petersson; [2023]
    Keywords : LWR; SMR; Water chemistry; Radiolysis; Boric acid; LWR; SMR; vattenkemi; Radiolys; Borsyra; Hydroxylradikal;

    Abstract : Ett problem vid byggandet av nya kärnkraftverk för elproduktion är de stora investeringskostnaderna samt den långa tiden det att få tillstånd för en reaktor och bygga den. Nyligen färdigställdes den tredje reaktorn vid Olkiluoto I Finland, den tog 18 år att färdigställa exklusive tiden att få tillstånd för reaktorn. READ MORE

  4. 3. Electrochemical behavior of conducting polymers

    University essay from KTH/Kemi

    Author : Raghda Kalifa; [2022]
    Keywords : Cathodic protection; conducting polymers; conductivity; structure; compression; Katodiskt skydd; ledande polymerer; konduktivitet; struktur; kompression;

    Abstract : Ett stort industriellt problem när det gäller metalliska material är korrosion. En metod för att förhindra korrosion är genom en elektrokemisk process som kallas katodiskt skydd vilket kan utföras på två olika sätt: Katodiskt korrosionsskydd med påtryckt ström (ICCP) eller offeranod (SACP).

  5. 4. Effekter av livsmedelsförädling för lokalkorrosion på rostfritt stål 316L

    University essay from Lunds universitet/Industriell Produktion

    Author : Fredrik Waldur; [2022]
    Keywords : Technology and Engineering;

    Abstract : Pitting corrosion on 316L stainless steel has been widely studied, but knowledge is lacking within food processing environments. A new test setup was developed to enable electrochemical measurements inside a heat exchanger (pasteurizer) where solutions can be heated and cooled rapidly, allowing for corrosion tests of solutions that do not withstand high temperatures for a long period of time.

  6. 5. Carbon capture in biomass combustion plants using promoted potassium carbonate solutions : A cost and safety evaluation

    University essay from Mittuniversitetet/Institutionen för kemiteknik

    Author : Håkan Bergman; [2022]
    Keywords : BECCS; carbon dioxide; potassium carbonate; bioenergy carbon capture and storage; promoter; BECSS; Koldioxidinfångning;

    Abstract : Biomass combustion can be seen as CO2 neutral, thereby biomass combustion plants can have negative CO2 emissions if retrofitted with post combustion capture (PCC) technology using liquid absorbents. Monoethanolamine (MEA) has been used for carbon capture in coal combustion plants but are not suitable for use in biomass combustion plants due to corrosion and high solvent regeneration cost.
