2. 1. Study of Sulfide Capacity of Slag and Sulfur Removal from Hot Metal

   Author : Adolfo Firmino Timoteo Condo; Du Sichen; Robert Eriksson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process science; Metallurgisk processvetenskap;

   Abstract : The present study aims at investigating the desulfurization process in hot metal and sulfide capacity of slags. The missing experimental data of sulfide capacities in Al2O3-CaOMgO-SiO2 system at 1713 K, 1743 K, 1773 K, 1823 K, 1873 K and in the Al2O3-CaO-SiO2 system at 1873 K were investigated under wellcontrolled oxygen potentials.

4. 2. A Study on Selected Hot-Metal and Slag Components for Improved Blast Furnace Control

   Author : Annika Andersson; KTH; []
   Keywords : ;

   Abstract : The main objective of this work was to gain an increasedunderstanding of selected blast furnace phenomena which couldbe utilized for an improved blast furnace process control. Thisthesis contributes with both a model study and an experimentalstudy on blast furnace tapping, and results from these findingscan be used to enhance the control of the blast furnace. READ MORE

   Author : Joel Gustavsson; Pär Jönsson; Leiv Kolbeinssen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blast furnace chemistry; ironmak ing; thermodynamics; silicon compounds; combustion; fuel injection; mass balance; slags; pig iron; gases; droplets;

   Abstract : The thermodynamic conditions for the behaviour of silicon in the lower part of the blast furnace have been the focus of the thesis. More specifically, the influences of temperature, carbon activity, total gas pressure and Fe reoxidation on silicon have been studied. READ MORE

6. 4. Subcooled boiling flow in liquid-cooled internal combustion engines

   Author : Sudharsan Vasudevan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Road transport sector contributes significantly to emission of carbon dioxide and other greenhouse gases, which negatively impact the global climate. Efficient management of energy, irrespective of the type of propulsion, has the potential to minimize fuel consumption and to reduce emission of greenhouse gases. READ MORE

7. 5. Sustainable Arsenic Mitigation A Strategy for Scaling-up Safe Water Access : A Strategy for Scaling-up Safe Water Access

   Author : Mohammed Hossain; Prosun Bhattacharya; Marinus Eric Donselaar; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bangladesh; drinking water; arsenic mitigation; local tubewell driller; sediment color tool; low-manganese; Intermediate Deep aquifer; Land and Water Resources Engineering; Mark- och vattenteknik;

   Abstract : In rural Bangladesh, the drinking water supply is mostly dependent upon manually operated hand pumped tubewells, installed by the local community. The presence of natural arsenic (As) in groundwater and its wide scale occurrence has drastically reduced the safe water access across the country and put tens of millions of people under health risk.
