Nanofiltration (NF) rejected effluent from TATA Steel, India having high concentration of chloride, sodium, potassium, manganese, magnesium, sulphate, calcium and iron was treated by electrocoagulation (EC) followed microfiltration (MF) process. Ceramic membranes were prepared Linz-Donawitz (LD) slag obtained Tata Steel Ltd, utilised for the separation electro-coagulated by-product. LD is a byproduct process which constantly produced as pig processed into crude steel. EC studied at various...
Abstract Medium coking coals from West Bokaro coalfield, India, were extracted with N-methyl-2-pyrrolidone (NMP) and ethylenediamine (EDA) under reflux condition at atmospheric pressure. The objective of the study was to maximize clean coal yield maintaining specified ash content. Experimentations using three level full factorial designs carried out elucidate importance variables such as extraction time, solvent ratio, filtration mesh size upon coal. To determine significance effects, Pareto...
Abstract This article describes characterization of a solvent-extracted Indian coal obtained from four different seams the West Bokaro mines. The samples were extracted with solvent N-methyl-2-pyrrolidone. Ethylenediamine was used as co-solvent. Extracts analyzed for elemental, microscopical and swelling properties. Functional group analysis conducted using Fourier transform infrared spectroscopy (FTIR). A comparative study made parent showed that extraction organic brings about considerable...
This work focuses on the preparation and characterisation of novel LD-slag (by product Linz-Donawitz process in Steel Industry)-based ceramic membrane. powder along with other pore forming binding agents such as boric acid, sodium metasilicate, carbonate alumina, were blended casted into membrane by simple paste casting method. The prepared sintered at 700 ºC was found to have enhanced temperature resistivity, mechanical strength excellent separation efficiency. had an average diameter...
This paper presents adaptive backstepping methodology for controlling polymerization process under parametric uncertainty and input saturation. In general complex chemical processes is a challenging problem due to the structural mismatch of parameters. Adaptive algorithm, whether linear or non-linear, an essential tool control such processes. Normally, nonlinear controllers are designed based on stability Lyapunov functions. A recursive design approach applied here constructing functions...
Evolution of hydrogen during the plastic state is a key parameter in coke making for production quality coke. Based on this phenomenon, new devolatilization method has been developed accessing coking property coals using evolution H2 thermogravimetric–mass spectrometer (TG-MS) analysis. Four having different potentials, commonly used steel industries, were considered. The investigation was performed at temperatures up to 1100 °C an argon atmosphere under constant heating rate 3 °C/min...
High-ash Indian coals and washery discards were extracted using an organic solvent. Complete characterization study was carried out in order to measure its coking potential. The revealed that swelling thermoplastic properties of the extracts are better as compared parent coals. A new concept for studying behavior coal is introduced access potential coal. series carbonization tests performed considering one blend components. reflects addition optimum amount base-coal blends helped improving...
The scarcity of water has driven every steel plant in India to pursue major conservation initiatives. R&D Tata Steel Jamshedpur invented an integrated and cost effective process for treatment reuse making gas cleaning (GCP) wastewater Linz-Donawitz (LD) slag quenching (SQ) wastewater. new consists mixing GCP with SQ a specific ratio followed by coagulant addition controlled carbon dioxide (CO2) sparging. average total suspended solid (TSS) dissolve solids (TDS) concentration treated were...
