  • Condebelt drying for pulp and paper industry

    Type: 
    Technology
    Sectors:
    Objective:

    The Condebelt drying process was patented in 1975. The Condebelt drying process was originally created to increase drying rates of paper. Condebelt drying produces approximately 10-15 times higher drying rates than conventional cylinder drying. These higher drying rates are achieved by higher contact temperatures, higher pressing between the hot surface and paper and relatively low thermal resistance between steam and paper in the Condebelt drying process.

    According to Retulainen (2001), three features of the technology warranted further investigation after the first pilot tests:

  • Oxyfuel Combustion in the Steel Industry: Energy Efficiency and Decrease of CO2 Emissions

    Type: 
    Publication
    Publication date:
    Objective:

    Compared with conventional oxyfuel, flameless oxyfuel provides even higher production rates, excellent temperature uniformity and very low NOx emissions. Since its commercial introduction in 2003, the leading supplier has made more than 30 installations of the flameless oxyfuel technology. This chapter describes the state-of-the-art oxygen technologies, including results from installations in the steel industry, and discusses their future possibilities to make steel production more effective.

  • CO2 Capture and Storage (CCS) in Energy-Intensive Industries

    Type: 
    Publication
    Publication date:
    Objective:
    Sectors:

    This website discusses the European Commission"s 2011 Roadmap for moving to a competitive low-carbon economy in 2050, emission reductions will be required to take place in all sectors, with carbon dioxide (CO2) emissions from the industrial sectors reduced by 34% to 40% by 2030, and by 83% to 87% by 2050. The only available technology that can provide the required large-scale emission reductions in European Union energy-intensive industries--such as steel, cement, refineries and chemicals--is CO2 capture and storage).

  • Direct casting for iron and steel sector

    Type: 
    Technology
    Sectors:
    Objective:

    The iron and steel sector is the second-largest industrial user of energy, consuming 616 Mtoe in 2007 and is also the largest industrial source of CO2 emissions. The five most important producers – China, Japan, the United States, the European Union and Russia – account for over 70% of total world steel production. A main technology in the iron and steel industry is the direct casting, which is the process of creating finished iron and steel products using moulds to shape the molten metal.

  • Corrosion Inhibitor Additives for Cathodic e-coating Al Alloys

    Type: 
    Product
    Objective:

    Additive-assisted cerium-based corrosion-resistant e-coating: Corrosion resistance of metallic components such as stainless steel components of vehicles and especially aluminum-based components of aircraft is enhanced by application of an e-coat paint or primer which is enhanced by incorporation of cerium ions into the e-coat electrolytic bath. The resulting overall coating includes a cerium-based layer under a cerium-enhanced e-coat paint or primer layer.

  • Advanced wet quenching for iron and steel sector

    Type: 
    Technology
    Sectors:
    Objective:

    The iron and steel sector is the second-largest industrial user of energy, consuming 616 Mtoe in 2007 and is also the largest industrial source of CO2 emissions. The five most important producers – China, Japan, the United States, the European Union and Russia – account for over 70% of total world steel production. A standard technique that is applied worldwide is the coke wet quenching of coke, where quenching vapors are bunkered before delivery to the atmosphere and subsequently or immediately a condensate is drawn off and cooled further.

  • Blast furnace slag granulation

    Type: 
    Technology
    Sectors:
    Objective:

    Cement is a global commodity, manufactured at thousands of plants. The industry is consolidating globally, but large international firms account for only 30% of the worldwide market. The principal and most visible market for cement is the construction industry in a multitude of applications where it is combined with water to make concrete. Most modern civil engineering projects, office buildings, apartments and domestic housing projects use concrete, often in association with steel reinforcement systems.
