World’s energy sources like petrochemical oils, natural gas and coal cause global warming environmental pollution. Therefore, the traditional must be replaced by renewable resources. Biodiesel has been recognized as one of effective, green, sustainable fuels. This paper investigates production biodiesel from sunflower oil using electric arc furnace dust (EAFD) a heterogeneous solid catalyst. Fo...

Abstract The technical and environmental aspects of treating electric arc furnace dust (EAFD) using a novel process including alkaline roasting organic acid leaching were evaluated compared to the globally applied conventional Waelz process. global warming potentials roasting–organic (with co-product credits) processes 7.48 4.71 kg CO 2 -eq with 33% Zn as feed material. However, decreasing cont...

Environmental degradation and Economic growth are two important proofs in sustainable development which are followed by steel industry. In this case, energy and environmental damages as sustainability patterns of environment have been investigated in three different dust collectors to select the most environmentally suitable dust collector for electric furnace. In this article, the consumption ...

The purpose of this study was to identify and assess dust exposure in Electrical Arc Furnaces for steel manufacturing. The major concern of steel making processes is dust generation and accumulation. The scope of this research paper focuses on different ways to improve current controls and make recommendations. In order to achieve the purpose, various goals were developed to identify the extent...

This paper present the results obtained by simulation for the functioning regime improvement of an UHP Electric Arc Furnace. Because the nonlinearity of the electric arc the EAF functioning regime are perturbed from three causes: the current harmonics, the reactive power and the unbalanced load. In this paper there are study the possibilities of harmonics filtering and compensate the reactive p...

The electric arc furnace (EAF) is used to produce high quality steel from steel scraps. The EAF uses plasma arc to generate heat for melting scarp or direct reduced iron (DRI). The liquid metal should be drained from the tap hole. Manual tapping operation of the EAF in the hot environment around the furnace is a potentially dangerous and time consuming task for the workers. Therefore, it is ess...
