Aspen Plus Fluidized Bed Reactor Simulation: Fluidized Bed Reactor (FBR) The fluidized bed reactor is a reactor in which the fluid from the bottom of the reactor keeps the solid catalysts suspended inside the reactor. This reactor has an advantage over traditional packed bed reactor because it has a better heat and mass transfer . In industry, the fluidized bed reactor is most prominently used to produce products which cannot be efficiently manufactured using more commonly using more commonly used reactors (Towler, 2012). A fluidized bed reactor is used to produce a variety of products. In the fuel industry, a fluidized bed reactor is used to produce gasoline, propane, butane, and propylene (Washington University, 2016). While these are some of the common uses of fluidized bed reactor, good mixing, and energy efficient nature of the reactor allows a fluidized bed to be used in producing a less conventional fluidized bed reactor product such as photovoltaic cells .

Introduction:   Process simulation is extremely beneficial to engineers, allowing them to further understand processes, identify process advantages and limitations, and provide quantitative process outputs and properties. Modeling reactors and their corresponding reactions is difficult by nature but can be rewarding if done correctly. This page provides essential information on the topic of reactor simulation using the computer program Aspen HYSYS .   Aspen HYSYS Reactor Simulation Basics: The HYSYS program allows the user to define reactions primarily based on desired model outputs and available information. After defining process components, the user can choose a reaction type as listed in the HYSYS reaction section below. HYSYS includes a number of different reactor models for the various reaction types, desired outputs, and specification limitations as well as standard PFR and CSTR models as described in the HYSYS reactors section below.  Unlike other si...
