  1. 1. Washing efficiency in the pulp mill : An evaluation of the washing efficiency in SCA Munksund's pulp mill

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Malin Malmberg; [2023]
    Nyckelord :Chemical Pulp; Lignin; COD; Pulp Washer; Kraft Pulping; Pappersmassa; Lignin; COD; Massatvätt; Sulfatmassaprocessen;

    Sammanfattning : Munksunds pappersbruk är ett integrerat massa- och pappersbruk som består av två fiberlinjer, en barr- och en lövlinje där båda kokarna är kontinuerliga med efterföljande tvättsteg. En kartering av COD (eng. Chemical Oxygen Demand) och natrium utfördes för båda linjerna för att utvärdera tvätteffektiviteten. LÄS MER

    Nyckelord :Catalytic Filters; Variable filter deployment; Wood stove Emissions; Eco Design 2022; Reduced Emissions; Katalytiska filter; Varierande filter; Utsläpp från vedkaminer; Eco Design 2022; Reducerade utsläpp;

    Sammanfattning : As of 2022 the European Union introduced a new Eco Design legislation which states emission limits for stoves sold in the EU. There are already requirements on emissions, but as both legislation are to be harder and there is a higher interest in Eco friendly products, there is an interest to study different ways to reduce the emissions from wood stoves.
