  2. 1. Management of technology in the process industries:  Matching market and machine

    Author : Peter Samuelsson; Pär Jönsson; Rob Boom; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process industries; manufacturing; innovation; configuration; strategizing; capability; configuration modelling; process industries; production system; physical modelling; AOD; converter geometry; injection; mixing times; electric arc furnace; EAF; post-combustion; high-impedance; network disturbances; operational results; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The process industries span multiple industrial sectors and constitute a substantial part of the entire manufacturing industry. Since companies belonging to this family of industries are often very asset intensive, their ability to respond to changes is often limited in the short term. READ MORE

  4. 2. A study of mold flux entrapment and gas entrainment in an ingot casting process

    Author : Jun Yin; Mikael Ersson; Pär Jönsson; Yogeshwar Sahai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mold flux entrapments; CFD; Gas entrainment; Ingot casting process; Uphill teeming process; Side teeming process; Numerical simulation; Non-metallic inclusions; Metallurgical process science; Metallurgisk processvetenskap; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The focus of this work is to study the gas entrainment and mold flux entrapments during the ingot filling process based on physical and numerical modelling.The formation of the free surface was investigated in the uphill teeming method, which illustrates a dynamic change at a quasi-steady state.

  5. 3. Utility Disturbance Management in the Process Industry

    Author : Anna Lindholm; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; utilities; process control; plant-wide disturbances; availability; buffer tanks;

    Abstract : Use of utilities, such as steam and cooling water, is very common at industrial sites. Utilities are often shared between several production areas, and a disturbance in the supply of a utility is therefore likely to affect a large part of the production site, and cause great loss of revenue.

  6. 4. Developments in Feedstock Analysis and Process Control for Biogas Production

    Author : Sten Strömberg; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Process control; Biochemical Methane Potential; Process analysis; Feedstock; Biogas;

    Abstract : A sustainable treatment of organic wastes, generation of renewable energy, reduction of green house gas emissions, limiting the eutrophication and closing the nutrient cycles are several environmental challenges for which anaerobic digestion may be a suitable solution. There is today a large amount of available organic waste materials that could serve as potential feedstock for biogas production. READ MORE
