1. 1. Safety Reviews of Technical System Modifications in the Nuclear Industry

   Författare :Thomas Falk; Sven-Ove Hansson; Teemu Reiman; KTH; []
   Nyckelord :safety; safety review; nuclear; nuclear power plant; process; process improvement; action research; experience feedback;

   Sammanfattning : The function of safety reviews (here understood as expert judgements on proposals for design modifications and redesign of technical systems in commercial Nuclear Power Plants, supported by formalised safety review processes) plays a fundamental role for safety in nuclear installations. The primary aims of the presented case studies includes: critically examining and identifying the main areas for improvement of the existing technical safety review process as it is conducted at a Swedish nuclear power plant, developing a new process, and evaluating whether any improvements were accomplished.

3. 2. VALUE CO-CREATION FOR SUSTAINABLE PRODUCT SERVICE SYSTEM DESIGN : OPPORTUNITY FOR GLOBAL MANUFACTURING COMPANIES

   Författare :Yan Zhang; Tobias Larsson; Andreas Larsson; Kent R Johansson; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Product-Service System; Manufacturing company; Innovation Framework; PSS design; Value Co-creation; Case study; Maskinteknik; Mechanical Engineering; Maskinteknik; Mechanical Engineering;

   Sammanfattning : There is a gradually spreading servitization trend that is forcing industrial manufacturing companies acting in the global market to rethink their business. Manufacturing companies that were traditionally perceived as product-centered, are today increasingly influenced by a service-oriented theory, which claims that manufacturing companies are driven to shift their business focus towards a strategy where customer-perceived value is in the spotlight, and where products are bundled with services to offer Product-Service Systems (PSS).

4. 3. Methods for improving performance of process planning for CNC machining : an approach based on surveys and analytical models

   Författare :Staffan Anderberg; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; CNC machining; metal cutting; performance; process capability; environment; energy; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Process planning as an enabler of competiveness is often overlooked, but being one of the principal function in the product realisation flow it holds a key role by combining both product and production requirements into a production concept with respect to the current manufacturing system. As such the capability of process planning to a large extent dictates production cost, lead times, product quality etc. LÄS MER

5. 4. Partial CO2 capture to facilitate cost-efficient deployment of carbon capture and storage in process industries - Deliberations on process design, heat integration, and carbon allocation

   Författare :Max Biermann; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon allocation; Partial CO2 capture; process industry; techno-economic assessment; CCS; heat recovery; amine absorption;

   Sammanfattning : Climate change requires that all energy-related sectors reduce drastically their greenhouse gas (GHG) emissions, at a global rate of 1–2 GtCO2 per year, starting now. Process industries, such as the iron and steel, cement, petrochemical, and oil-refining industries, are inherently carbon-intensive, and carbon capture and storage (CCS) is one of the few options available to achieve the required deep reductions in carbon dioxide (CO2) emissions.

7. 5. Chemical and Biochemical Biorefineries in Kraft Pulp Mills – Process Integration and Economics for Three Concepts

   Författare :Valeria Lundberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bottleneck; ethanol; biorefinery; energy efficiency; process integration; pulp mill; high gravity;

   Sammanfattning : Some of the advantages of integrating biorefinery concepts with kraft pulp mills are that the utility system can be shared and that mass and energy streams can be exported from the pulp mill to the biorefinery or vice versa. These measures may result in lower investments and operating costs for the biorefinery compared with stand-alone operations. LÄS MER
