| description | The main aim of the work was to investigate if simple reactor blocks could be combined to adequately represent complex reactor configurations; with the objectives of selecting an appropriate reaction scheme, creating a working simulation and validating the results obtained from the simulation. An ethane cracker reactor is simulated using Aspen Plus, for a molecular reaction scheme, made up of seven reactions and eight hydrocarbon components; using the kinetics and reactor geometrics. Several assumptions were made such that the fired furnace reactor could be modeled as a series of two plug flow reactors using Aspen Plus. Modeling of a fired furnace reactor for the cracking of ethane is made difficult by the inherent separation between the convection and radiation sections; a difficulty which was overcome by separating the convection region and the radiation region of the fired furnace reactor into two simulations such that temperatures were solved for iteratively. A firebox simulation was created with the intent of finding the optimal fuel and air flow rates that would supply the fired furnace rector with the required 2490 kW; these flow rates were found to be 190 kmol hr−1 and 60 kmol hr−1. |
