Enhanced Recovery by Hydrotropes in Oxidized Coal Flotation
Abstract: AbstractSo far flotation proved its best in improving the concentration of low grade fines by recovering the maximum with the use of advanced flotation reagents. In this context we propose the process optimization with the use of hydrotropes as activators in the coal flotation process. It is observed that sodium benzoate a known hydrotrope helped in increasing the recovery of the concentrate percent from 12.8% at plant condition to 31% …

Techno-Economic Analysis of Packed Bed Type Thermal Batteries for Surplus Renewable Energy Storage
Abstract: Low carbon electricity from renewables will form the bed rock of the energy transition necessary for climate change mitigation. However, variable renewable generators suffer from intermittency and variability – there can be large surplus power available at times which cannot be dispatched to the grid. At many times, the practice is to curtail surplus renewable output, which is wasteful and not economic. There are also phases when generation is not …
