463156 Predicting Nitrosamine Formation in Amine-Based Carbon Dioxide Capture Systems with Aspen Plus Simulation
In this study, a simulation module was developed to predict nitrosamine formation in industrial-scale carbon dioxide capture systems. Aspen Plus is currently the most widely used simulation software for predicting the carbon dioxide capture performance of industrial-scale systems. However, there is no available simulation module in Aspen Plus to assess the formation of nitrosamines. To develop a rigorous simulation module, potential chemical reactions associated with nitrosamine formation were integrated. A rate-based multi-stage simulation was performed with RadFrac block, incorporating heat and mass transfer correlations accounting for column characteristics and hydraulics. The simulation indicated that our module is able to estimate nitrosamine concentration as low as ppm level in the bulk solution. This simulation module offers a robust and efficient strategy to evaluate the risk of nitrosamine formation from carbon dioxide capture systems.
