Aspen HYSYS Petroleum Refining Catalytic Reformer Model 

This section discusses the key features of the Aspen HYSYS Petroleum Refining model we use throughout this work. While the features we discuss are specific to Aspen HYSYS Petroleum Refining, there are other simulation programs that have similar functionality. The goal of this section is to discuss the key features of the simulator that are relevant to developing an integrated reaction and fractionation model. 

The feed lumping technique in the Aspen HYSYS Petroleum Refining model relies on a base of compositions and a method to correct those measured compositions based on changes in measured bulk properties. The feed is broken into many (4-14) lumps for each chemical group. Typically, these measured properties are the distillation curve and total PNA content In our work, we have access to detailed feed composition information, so we do not use this technique. However, we have developed an alternate technique of feed lumping based on minimal base composition data and bulk property requirements. We discuss this technique in a subsequent section. 

The reaction network in the reactor model is similar to the network presented by Froment etal. [12] and Taskar [4], However, the reaction network supports higher aromatics up to C14. While these typically are not expected in reformer feeds, the kinetic model can handle them as well. In addition, the reactor model includes paths for the undesired hydrogenolysis reactions. These highly exothermic reactions do not occur in any significant degree in stable reforming units. However, older reactors may display this behavior so it is important to model them as well.

In the following workshops, we demonstrate how to organize data, build and calibrate a model for a catalytic reformer using Aspen HYSYS Petroleum Refining. We discuss some key issues in model development and how to estimate missing data required by Aspen HYSYS Petroleum Refining. We divide this task into four workshops ...
