Flotation technique: Its mechanisms and design parameters

Abstract: A knowledge of hydrodynamic characteristics is important because it helps in design, control, analysis, optimization, operation, and modelling of the system, which enhances the performance of process unit. This paper aims to provide the evaluation of the techniques of flotation and design parameters, which is required to improve the separation efficiency of the flotation processes. Different components of flotation columns, flotation mechanism and design parameters like flow regime, gas holdup, bubble size and its distribution, mixing characteristics and carrying capacity are critically discussed. The measuring techniques of design parameters for flotation process are also described. The present article on flotation technique and its research components may provide in hand information on the flotation process to the researcher and designer of flotation unit.

A Multi Charging Station for Electric Vehicles and Its Utilization for Load Management and the Grid Support

Abstract: This paper discusses the modeling of a multi charging station for Electric Vehicles (EVs) and its utilisation for grid support. Allowing the EVs to charge and discharge without any control may lead to voltage variations in the grid. However, if the charging/discharging of the EVs is done in an intelligent fashion, they can act as distributed energy sources and can smoothen the load profile of the distribution network by providing peak shaving and valley filling. The presented work mainly focuses on the control architecture for using the EVs' batteries as distributed energy storage systems. This enables in maintaining the node voltage within the prescribed limit by valley filling and peak shaving. The control architecture is based on fuzzy control techniques. The proposed architecture is implemented on the distribution network of Guwahati city. Dynamic load profile is used to check the effectiveness of the proposed architecture for flattening the load profile.
