  1. 1. Improvements in Energy Efficiency of Vacuum Dewatering of Greaseproof Paper : Simulation of a Triple Vacuum Suction Box in Laboratory Scale

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

    Författare :Björn Öman; [2023]
    Nyckelord :Vacuum dewatering; greaseproof paper; triple vacuum suction box; grammage; energy efficiency; dryness; Vakuumavvattning; greaseproofpapper; trippelvakuumsuglåda; ytvikt; energieffektivitet; torrhalt;

    Sammanfattning : Vacuum dewatering of paper is a heavily energy expensive process, even more so for greaseproof paper, which is one of the main products at Nordic Paper Seffle AB. Due to this being such an energy demanding process, improvements in the vacuum dewatering could save massive amounts of energy. LÄS MER
