  • Biorefinery

    Type: 
    Technology
    Sectors:
    Objective:

    With the surge in bio-based activities around the globe, a new concept called bio-refining starts to emerge. IEA Bioenergy Task 42 on Biorefineries defines biorefining as “the sustainable processing of biomass into a spectrum of marketable products and energy”. A bio-refinery combines/integrates a series of biomass conversion technologies to produce a range of products and (base-)materials, such as food, feed, chemicals, materials, oil, gas, heat and/or electricity. The concept is similar to a conventional oil-refinery where multiple petroleum products and fuels are produced.

  • 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:

  • 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.

  • Ammonia

    Type: 
    Technology
    Sectors:
    Objective:

    Ammonia is the main product of the fertilizer industry. Developing countries account for the majority of worldwide production. About 77% of ammonia production is based on steam reforming of natural gas, with most of the remaining production based on heavy-oil or coal-based processes. A further shift from heavy-oil or coal-based to gas-based processes can strongly reduce energy use and emissions.

  • Biopolymer production for (petro-)chemical sector

    Type: 
    Technology
    Sectors:
    Objective:

    A polymer is a large molecule (macromolecule) composed of repeating structural units typically connected by covalent chemical bonds. Examples of synthetic polymers are plastics, Bakelite and nylon, while rubber, proteins, DNA but also spider-silk are naturally occurring polymers or so-called natural bio-based polymers. Reproducing naturally occurring and/or synthetic polymers based on non renewable fossil feedstocks is common practice in the (petro-) chemical industry.

  • 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.

  • CCS from cement production

    Type: 
    Technology
    Sectors:
    Objective:

    CCS is a new technology, not yet proven at the industrial scale in cement production, but potentially promising. CO2 is captured as it is emitted, compressed to a liquid, then transported in pipelines to be permanently stored deep underground. 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.

  • Coke dry quenching for iron and steel sector

    Type:

The five most important producers – China, Japan, the United States, the European Union and Russia – account for over 70% of total world steel production. Coke dry quenching appears as the most valid system to reduce air pollution allowing at the same time a remarkable energy recovery or saving, especially when it is associated with coal preheating.
