Jan 20, 2006· hey! i had a similar problem. I had to simulate a fixed bed reactor though adn i found out that its just not possible in hysys!!! so basically i used a PFR and gave in the appropiate equations and, trust me, it worked very very well. so basically approximate your fluidised bed to a packed bed and enjoy!

A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst possibly shaped as tiny spheres) at high enough velocities to suspend the solid and cause it to behave as though it were a fluid.
Consequently, fluidized-bed reactors, which have high heat and masstransfer efficiencies, are major current areas of investigation for DME productionfrom syngas. In the present paper, the comprehensive reactor model proposed byMahecha-Botero et al. has been modified and employed to simulate DMEsynthesis in a fluidized-bed reactor.

Coal gasification with O2 and H2O in a fluidizedbed reactor involves pyrolysis, combustion and steam gasification. Gasification in fluidized bed offers advantages, since fluidized beds are capable of being scaled up to medium and large scale, overcoming limitations found in smaller scale, fixedbed designs.

The fluidized bed reactor module shown in Fig. 3 has two entrance and two exit ports. Via material streams connected to these ports the fluidized bed reactor module is integrated into the process flowsheet. The material streams transfer information from one unit to the next. The entrance ports of the fluidized bed reactor module connect to the ...
In this study, the sequential modular model is introduced to simulate a circulating fluidized bed reactor by integrating the kinetic and hydrodynamic sub-models into logically-ordered ideal chemical reactors through subroutines.
