Hydrogen plays a key role in the European Green Deal
European Commission President Ursula von der Leyen launched the European Green Deal last Wednesday, on 11 December. The goal is ambitious. If the European Green Deal becomes reality, the European Union will become climate neutral by 2050. To reach the goal, the EU will have to overturn almost every policy area. Europe inevitably needs hydrogen to reach this arduous goal. Looking at the ...

Clay Insulation Brick
Diatomite brick is a kind of Clay Insulation brick. Thermal Insulation Bricks are high porosity refractories with low thermal conductivity and high porosity (no less than 45%) used to reduce heat losses and thus to maximize heat conservation within the furnace. Clay Insulation brick Characteristics ●High porosity ●Low volume density ●Low Thermal conductivity Clay Insulation Bricks ...

High Alumina Bricks
Main introduction of the High alumina bricks High alumina brick, also known as high alumina fire bricks or high alumina refractory bricks, refers to fire brick containing Al2O3 more than 48%, which is made of high grade bauxite through high temperature calcinations. High alumina brick is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. It ...

NaA zeolite derived from blast furnace slag: its application for ammonium removal
In this paper, high value added NaA zeolite material was prepared from blast furnace (BF) slag by hydrothermal method and its adsorption behavior on the removal of ammonium ion was investigated. It was found out that the synthetic NaA cubic zeolite with smaller crystal size obtained at nSiO2/nAl2O3 = 2 and nH2O/nNaOH = 20 showed better adsorption performance. The kinetics of the adsorption of ...

Case study - LKAB, Sweden
Customer: LKAB, Sweden Project: WetESP pressurized - Processgases Blast Furnace Year 1997 LKAB installed a pilot Blast Furnace at Swerea- MEFOS, Luleå. The product gas contains both CO and H2. The Blast Furnace operates at 0,8 bar over pressure. The design pressure for the WESP is 1,5 bar. The emission standards for dust are < 10 mg/Nm3. This gave WESP as the optimal choice. Result; ...

Syngas monitoring - Purpose of gas monitoring in DRI plant
The use of process gas online monitoring systems at locations such blast furnace gas outlet, converter off gas exhaust and coking gas outlet is very reasonable in order to analyse the fuel gases composition by measuring the concentration of CO, CO2, O2, N2, CH4, and H2. There from the calorific value BTU and the Wobbe Index WI can be accurately calculated. Modern steel plants uses dedicated ...

Case study - Fly ash concrete design for Chicago’s 100-year road structure
After years of heavy use, Wacker Drive, a major two-level viaduct in downtown Chicago, Illinois needed to be rebuilt. The Chicago Department of Transportation (CDOT) set ambitious goals for the $200 million concrete structure because of its central location and importance to downtown traffic flow. The end result is a more durable roadway with a service life of 75 to 100 years. Originally built ...

Full probabilistic service life prediction and life cycle assessment of concrete with fly ash and blast–furnace slag in a submerged marine environment: a parameter study
Nowadays, more attention is being paid to sustainability in construction. Over the years, the concrete research community has developed a wide range of potential 'green' concretes. To reduce cement related CO2 emissions, a considerable part of the traditional binder can be replaced with industrial by–products. However, as a result of the current focus on comparative durability assessment based on ...

Plan B efficiency and conservation measures drop energy demand by 2020
Projections from the International Energy Agency show global energy demand growing by close to 30 percent by 2020, setting the stage for massive growth in the carbon dioxide emissions that are warming our planet. But dramatically ramping up energy efficiency would allow the world to not only avoid growth in energy demand but actually reduce global demand to below 2006 levels by 2020. We can ...

Thermochemical reactor design and thermal breakdown in middle-rank coals
Experiments conducted at bench scale can throw new light on the operation of pilot and plant scale processes. In the coal gasification/combustion area, such experiments have ranged from determinations of coal reactivities for novel entrained-flow gasifiers, to investigating the fate of injectant coal during blast furnace operation. Meanwhile, the accurate mimicking of conditions within pilot and ...

Raising energy efficiency in a new materials economy - Part I
The production, processing, and disposal of material in our modern throwaway economy wastes not only material but energy as well, thus producing unnecessary, climate-disrupting carbon dioxide emissions. In nature, one-way linear flows do not survive long. Nor, by extension, can they survive long in the expanding global economy. The throwaway economy that has been evolving over the last ...

Waste co-incineration in the European Community, is the sky the limit?
The co-combustion of waste in industrial furnaces -co-incineration- attracts considerable interest in the European Community, because of the combination of perceived business incentives, regulatory developments, and the slate of available technological options. It was found, however, that EU-regulation developed to ensure safe and environmentally acceptable processing of waste represents a clear ...
