Abstract

This project discussed about the project titled "Particle Flow in Moving Beds". This report consists of the project's background, objectives, problem statements. scope of work, literature review, methodology, results, discussions and conclusion. In this work, the author reports a study of solid particle flow in moving bed reactor. In moving bed reactor, the catalyst which is solid particle will flow downward from top to the bottom and it will be recycling back to the top after regeneration. Meanwhile. the gases will cross-flow through the catalyst from the side through the moving beds. In this project, the author will use L-Valve as the representation of the moving bed reactor. There are a few parameters the effect the particle flow in the moving beds. Parameters that will be discussed in this study are aeration rate and particle flow in L-Valve. The relationship of these two parameters will be investigated in the series of experiment to determine how particle flow in the L-Valve affected by aeration rate. From the result of this experiment, an equation will be tested to know how the particles flow in the L-Valve given certain aeration rate. Moreover, this relationship can be used as a solid flow control in the crossflow rice dryer. The uses of relationship of aeration rate and the solid withdrawal can be used to replace screw mechanism that energy consuming in the removal dried rice in cross-flow dryer. In addition of this experiment. the rice dryer with the counter flow gas drying will be modeled. The rice dryer will be based on the California rice dryer type but with multiple stacks.
