How To Simulate A Fluidised Bed Reactor On Hysys -

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!
