  1. 1. Process modelling based on data from an evaporation and a CTMP process : Analysis of energy efficiency and process variability

    Författare :Daniel Ekbåge; Lars Nilsson; Helena Håkansson; Per Engstrand; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CTMP; process modelling; evaporation; energy efficiency; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, paperboard, steam and other important components. Improved energy efficiency supports sustainability of the process and the products. LÄS MER

  3. 2. A generic construction process modelling method

    Författare :Vesa Karhu; KTH; []
    Nyckelord :process; modelling; generic; method; database; view;

    Sammanfattning : A variety of modelling methods has been used to modelconstruction processes and projects, either during normalproject planning or for process re-engineering efforts orresearch. One common method, which is widely used byconstruction industry practitioners, is scheduling. LÄS MER

  5. 4. Model-Driven Process Design : Aligning Value Networks, Enterprise Goals, Services and IT Systems

    Författare :Erik Perjons; Paul Johannesson; Anders G. Nilsson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; business process design; e-process design; model-driven methods; enterprise modelling; business modelling; enterprise goals; services; value networks; business-IT alignment; design science; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : The purpose of business-IT alignment is to optimise the relation between business and IT in order to maximise the business value of IT. Successful business-IT alignment can be enabled by business processes and e-processes functioning as adaptive mediators between business and IT systems. LÄS MER

  7. 5. Process Optimization of UV-Based Advanced Oxidation Processes in VOC Removal Applications

    Författare :Francesco Montecchio; Klas Engvall; Roberto Lanza; Ernest Blatchley III; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOP; UV; photocatalysis; ozone; air pollution; VOC abatement; reactor design; reactor modelling; photocatalyst support; electrochemical treatment; electrochemical etching; irradiation modelling; kinetics modelling; fluid dynamics simulation; prototype; full-scale; CFD simulation; Chemical Engineering; Kemiteknik;

    Sammanfattning : Air pollution is a major concern in developed countries due to its hazardous health effects. Recent studies by the WHO (World Health Organization) estimate that urban air pollution causes a number of diseases of the respiratory tract and is associated with 150,000 deaths each year. LÄS MER
