Behavior of Packed Bed Thermal Storage
A packed bed thermal storage has several desirable characteristics to be used for energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (K1), conduction effect (K2) and air capacita...
متن کاملOptimal synthesis of rotating packed bed reactor
Rotating packed bed (RPB), a novel apparatus involving process intensification (PI), has been successfully used in the chemical industry in recent decades. In this paper, we establish a connection between process integration and process intensification for which we propose a superstructure involving a RPB and a packed bed (PB) in order to determine the optimal integrated design. We describe mod...
متن کاملStability of cellulose-based carriers in batch and packed-bed reactors
Abstract: The selection of a suitable type of reactor for the reaction with enzymes immobilized on the carriers is extremely important to industry. In this study the possibility of using pre-selected cellulose-based carriers (Granocel) to conduct the reaction in a stirred batch reactor and a fixed-bed reactor was investigated. It was shown that non-activated Granocel did not undergo compression...
متن کاملAdiabatic Reverse Combustion in a Packed Bed
Downward propagation of a combustion front in a packed bed of wood particles, with air supply from below, is examined theoretically and experimentally. Using a single-step reaction, with a kinetic model of char oxidation as the dominant mechanism, and assuming local thermal equilibrium, but allowing a local chemical nonequilibrium between the solid and gas phases, the front speed u F, the adiab...
متن کاملModelling of Displacement Washing of Packed Bed of Fibers
The mechanism of displacement washing of packed bed of porous, compressible and cylindrical particles, e.g., fibers, is presented with the help of an axial dispersion model involving Peclet number (Pe) and Biot number (Bi). Bulk fluid concentration, intra-pore solute concentration and concentration of solute adsorbed on the fiber surface are taken to be the function of washing time and position...
