As the initial step, the units and the components which exist in the system should be set and the property method which is similar to the fluid packages of Aspen HYSYS must be selected to closely model the solids in the actual system. Once all the specification is made, then the input and output streams of the reactants and products must be connected to the bottom and top of the reactor respectively. In addition, the inlet and outlet stream of solid particles must be connected to the left and right sides of the reactor respectively, even though the actual physical system may not have a solid particle stream entering or leaving the reactor. However, if a fluidized bed reactor requires a means of recovering the catalyst solid, a cyclone and a dryer may be used together to achieve to recover the solid particles. Generally, cyclone is a more effective way of separating gas from solid than gravity settling chamber (Peters, 2003). However, fabric filters, venturi scrubbers, and dry electrostatic precipitators are other options for separating solid from gas (Seider, 2004). Also, if there is a need to dry the solid particles, a dryer can be used. Specifically, if the solid particles are sensitive to thermal decomposition, spray drier may be used, as long as the catalyst can withstand the high pressure required for droplet formation (Ulrich 1984). Finally, after all the necessary equipment is set up in the simulator, the mesh and distribution function is checked to see if the reasonable output is obtained from the simulation.
