  • Metal Industry Emissions

    Type: 
    Publication
    Publication date: 
    Sunday, January 1, 2006
    Objective: 
    Sectors: 

    This chapter of the 2006 IPCC Guidelines for National Greenhouse Gas Inventories gives guidance for estimating greenhouse gas (GHG) emissions from the production of metals. Specifically, it covers emissions from the production of iron and steel and metallurgical coke, ferroalloy, aluminium, magnesium, lead and zinc. It asks for special care in the estimation to avoid double counting or omitting carbon dioxide (CO2) emissions from fuel combustion. It also highlights that CO2 capture and storage is not covered in this chapter.

  • Estimation of HFC-23 Emissions from HFC-22 Manufacture

    Type: 
    Publication
    Publication date: 
    Saturday, January 1, 2000
    Objective: 
    Sectors: 

    This report provides IPCC guidelines to countries on how to estimate and report to the UNFCCC their HFC-23 emissions from HCFC-22 manufacturing in their greenhouse gas inventories. It outlines options and issues for good practice guidance in the national inventory management for HFC-23 emissions, including methodological issues, reporting and documentation and inventory quality. Measurement of HFC-23 emissions using a Tier 2 approach is highly accurate because data reflect conditions specific to each plant.

  • Achieving Water Security in Japan and Worldwide

    Type: 
    Publication
    Publication date: 
    Thursday, January 1, 2009
    Objective: 
    Sectors: 

    According to this brochure, the world is now facing water challenges on a global scale. Climate change will continue to affect our water resources, at a time when the world is still struggling to achieve water-related millennium development goals (MDGs). Japanese culture and society were shaped in a diverse natural environment with climates ranging from subtropical to subarctic. Subject to recurring droughts and floods, Japan has learned to efficiently use and share water, and has developed various water technologies with a strong sense of thrift.

  • COP21 / Business Dialogue – 3rd session

    Type: 
    Event
    Date: 
    06 October 2015
    Country: 

    In the lead-up to the Paris Climate Change Conference (COP21) in December this year, Business Dialogue – 3rd session will be held in Tokyo, Japan. CTCN director Jukka Uosukainen will present the place and role of technologies in the climate negotiations.

    The event will also highlight COP21 updates, the role of innovation in delivering the Paris Agreement, the role of technology roadmaps in the energy transition, etc.

  • Sinter Plant Heat Recovery (Steam Recovery from Sinter Cooler Waste Heat)

    Type: 
    Product
    Objective: 

    This device recovers the sensible heat in the hot air with temperature of 250 C to 450 C from a sinter cooler. It comprises mainly; a)boiler/economizer, b)pure water feed device, c)deaerator, d)steam drum, etc.
    After heat exchange with sintered ore of 500 C to 700 C in the cooler, the exhaust gas is introduced to the boiler/economizer to generate steam and is recycled to the cooler.

  • Coke Dry Quenching (CDQ)

    Type: 
    Product
    Objective: 

    The heat recovered by inert gas is used to produce steam, which may be used on-site or to generate electricity. Hot coke from the coke oven is cooled in specially designed refractory lined steel cooling chambers by counter-currently circulating an inert gas media in a closed circuit consisting of 1) cooling chamber, 2) dust collecting bunker, 3) waste heat boiler, 4) dust cyclones, 5) mill fan, 6) blowing device (to introduce the cold air from the bottom), 7) circulating ducts.

  • Sinter Plant Heat Recovery (Power Generation from Sinter Cooler Waste Heat)

    Type: 
    Product
    Objective: 

    This is a waste gas sensible heat recovery system from sinter cooler to generate electric energy. The system is composed of dust collector, waste heat recovery boiler as steam, circulation fan and power generator by steam turbine.
    The values of cost and effect are obtained from a system configuration of two identical sintering machines, coolers each equipped with waste heat recovery boiler and one unit of electric power generator, to which the steam from two boilers is led.

  • Top Pressure Recovery Turbine (TRT)

    Type: 
    Product
    Objective: 

    This system generates electric power by employing the heat and pressure of blast furnace top gas to drive a turbine generator. After the blast furnace gas is used in power generation, it is used as a fuel in iron and steel manufacturing processes. Blast fumace gas (BFG) has a pressure of 0.2-0.236 MPa (2-2.41 kg/cm2) and temperature of approx. 200 C at the fumace top.

  • Reverse osmosis membrane technology

    Type: 
    Product
    Objective: 

    Membrane which permeates solvent (water) but does not permeate solute (salt). In desalination, pressure up to 10MPa is applied to seawater which enables water to pass through the revere osmosis membrane, while the salt is excluded.

    Currently, two types of material are used: bridged aromatic polyamides, and cellulose acetate. Membranes must withstand high pressure and also be resistant to fouling.

  • Converter Gas Recovery Device

    Type: 
    Product
    Objective: 

    Molten steel is produced by the converter process. This device recovers and uses the high temperature waste gas generated in large quantity during blowing in the converter (basic oxygen furnace: equipment used to produce crude steel from pig iron, steel scrap, etc.). Accompanying this process, about 100Nm3 of high temperature gas (CO) with a heating value of approximately 2,000 kcal/Nm3 is generated.
