Modelling the Effect of Porous Iron Sulfide Layers on Sour Corrosion Behaviour
Get PDFSurface layers and deposits of iron sulfides formed from sour corrosion may exhibit both protective and corrosive properties, depending on the types of iron sulfide formed and the physical structure of the layers. The protective barrier and blocking effects of the layers may be counteracted by significant cathodic activity on the surfaces of electrically conductive iron sulfides and galvanic corrosion of the underlying steel surface. Experimental and modelling work were performed to quantify the effects that parameters such as layer thickness and porosity, H2S partial pressure, temperature and pH can have on the electrochemical reactions, aqueous equilibria and mass-transport processes governing the corrosion rate. The results were discussed in the light of available literature and compared to relevant sour corrosion data, including both native corrosion product layers and applied iron sulfide deposits (UDC).

Carbon capture – from waste to energy: a stylized case from a pioneering initiative at Klemetsrud, Oslo. Report to the CLIMIT – demo project 618215: Potential for financing and pricing Carbon Capture in Waste-to Energy Installations in cities
Get PDFOslo has recently been given the European Environmental Capital award for 2019, following its adoption of an ambitious green strategy of reducing CO2 emissions by 50% by 2022, and by 95% by 2030. A core premise for Oslo reaching its goals is, however, that the city’s waste to energy plant installs carbon capture for sequestration (CCS). With 400,000 tons of CO2 emissions per year (Fortum 2019), Oslo’s Klemetsrud waste to energy plant is the largest single point carbon emitter in the city, and with these emissions it will be impossible for Oslo to reach its CO2 targets. However, carbon capture at Klemetsrud also carries significance in a wider global climate perspective. Global climate models are increasingly reverting to CCS in order to arrive at scenarios that are compatible with the Paris Agreement . This has created new pressure for CCS implementation, and Klemetsrud – if successful – could be an important trigger for CCS in Europe. This report is a styilized business case study of the Klemetsrud CCS project in light of four different regulatory scenarios.Carbon capture – from waste to energy: a stylized case from a pioneering initiative at Klemetsrud, Oslo.
