    Sammanfattning : Since district heating is the most common way of space heatingin Sweden, continual improvements of theefficiency of production and distribution of district heating is crucial. The purposeof this report is therefore to, using Kalmar Energi as an example, study how the production and distribution of district heating is affected by introducing a bypass pipeat a critical point in the network, and to investigate howcost efficiency might be achieved.

  3. 2. Provtagning av trädkärnor för att bedöma föroreningsgraden av klorerade lösningsmedel i grundvatten

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

    Författare :Daniel Nordborg; [2006]
    Nyckelord :Chlorinated solvents; CAH; chlorinated aliphatic hydrocarbons; tetrachlorethylene; trichloroethylene; chloroform; trees; tree cores; phytoremediation; contamination; Helgö.;

    Sammanfattning : Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. LÄS MER
