Abstract

The conventional spouted bed has presented several limitations that restrict the use on an industrial scale. Thus, studies of different methodologies and configurations have been performed to overcome such limitations. Limited processing capacity (scaling-up) and the energy issues are some of the main problems considered from an industrial point of view. Alternatives as a heat recovery system lost in the exhaust air, intermittent drying, and draft tube can be promising and have not been explored in the spouted bed. Therefore, the main objective of the current Ph.D. project is to design a spouted bed with a heat recovery system lost in the exhaust air, coupling methodology of the intermittency and the use of the draft tube. Two types of intermittency (reduction and total interruption of the air flow) and five different intermittency profiles will be evaluated, including the use of time-variant intermittency ratios. Alumina, soybean, and barley will be used as particulate materials. Three types of draft tube will be employed: porous, nonporous, and open-sided. Modeling and Pinch analysis will be performed to optimize the equipment developed. Energy and Pinch analysis will be carried out to investigate the performance of the designed equipment. Thus, the current Ph.D. project aims to obtain an energy efficient equipment with suitable and feasible characteristics for industrial applications. (AU)
