Introduction
Process simulation is extremely beneficial to engineers, allowing them to further understand the process, 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 section below.
Limitations
Because simulation requires reaction characteristics, parameters, and other information, it is important to conduct background research appropriate to the reaction of interest before beginning the actual simulation. If theoretical or empirical data do not exist for the reaction, it may be difficult or impossible to conduct a computer simulation (see Additional Options). Of course, the phase of the reaction must be known; unfortunately, however, HYSYS does not support solid phase modeling[1] and thus a different approach must be chosen.
