467318 Enhancing the Value of Detailed Kinetic Models through the Development of Interrogative Software Applications
A user-friendly I/O (Input/Output) converter application permits execution of molecular-level composition and kinetic models in a manner which focuses on measurable inputs and outputs. This app was used to efficiently study the impact of different feed streams, operating conditions, hydrogen partial pressure and catalyst flow rate on performance of a catalytic reactor. Such I/O converter apps are process-specific as the app is dependent on the process I/O. A second application, the KME Reactor Flowsheet tool, was developed to build kinetic models based on data from a pilot or commercial reactor which can split feed streams and perform reactor bypasses. It also includes different features like splitters, heaters and reactor blocks and also can handle multiple kinetic models.
The functionality of these applications is tested to study the behavior of a catalytic reforming unit. The inputs to the model are distillation, overall and detailed PIONA, density, and reactor conditions. The outputs from the model are light-gas yields, detailed PIONA, coke, and temperature drops across each reactor bed. The I/O converter and flowsheeting applications were used to study the impact of feed variation, partial pressure of hydrogen and catalyst circulation rate on yield, composition and coke concentration in the product.
