This paper examines the GHG emission of industrial process in Shenyang city, in the Liaoning province of China, using the 2006 IPCC greenhouse gas inventory guideline. Results show that the total GHG emissions of industrial process has increased, from 1.48 Mt in 2004 to 4.06 Mt in 2009, except for a little decrease in 2008. The cement industry, and iron and steel industries, are the main emissi...

The molten iron allocation problem (MIAP) is to allocate molten iron from blast furnaces to steel-making furnaces. The allocation needs to observe the release times of the molten iron defined by the draining plan of the blast furnaces and the transport time between the iron-making and steel-making stages. Time window constraints for processing the molten iron must be satisfied to avoid freezing...

Iron ore and coal together account for about 72% of cost of input materials in Indian steel plants. Moreover, sourcing iron ore and coal for steel plants is posing multitude of challenges including availability, quality and logistics. At present it is found that high quality input materials are hard to reach and easy to reach ones are of lower quality. Hence efficient utilisation of lower quali...

OBJECTIVE To evaluate the effect of two types of iron pots on haemoglobin (Hb) and serum ferritin (SF) concentrations in young children (6-24 months), adolescent girls (11-15 years) and women of reproductive age (15-44 years), whose households were provided with iron pots for cooking food over a period of 6 months, compared with controls. DESIGN AND METHODS We randomly assigned 161 households...

There is a rapidly increasing demand for iron resources with the fast-paced development of the iron and steel industry. For this reason, the iron and steel industry is facing the risk of a raw material shortage. Deposits of high-phosphorus iron ores are widely spread worldwide, but the use of these deposits in industry is limited owing to the high phosphorus content, which affects the cost of t...

Samples of concrete contain various waste materials, such as iron particulates, steel balls of used ball bearings and slags from steel industry were assessed for their anti-radiation attenuation coefficient properties. The attenuation measurements were performed using gamma spectrometer of NaI (Tl) detector. The utilized radiation sources comprised 137Cs and ⁶⁰Co radioactive elements with photo...

Self-provided power plants are set up in order to maintain normal operation some high energyconsuming industries the era of shortage China. In a specific historical period, it effectively alleviated problems insufficient supply and low reliability grid, promoted rapid development national economy. The construction self-provided steel industry is save electricity costs improve operational import...

Abstract The iron and steel industry generates around 10 % of global greenhouse gas emissions. bulk the emissions originates from ore reduction. In this reduction, coal is used as a reagent. Steelmakers could switch to hydrogen-based direct reduction using hydrogen instead reagent reduce pig iron. This would eliminate CO 2 equivalent process in traditional blast furnace. However, requires massi...
