How To Simulate A Fluidised Bed Reactor On Hysys - Student

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!

Fluidized bed reactor - Wikipedia

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.

AspenHysys Simulation of Methanol to Dimethylether (DME)

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.
