Analysis of Mass Transfer Performance of Monoethanolamine-Based CO2 Absorption in a Packed Column Using Artificial Neural Networks

Abstract: Exact and reliable estimation of mass transfer performance is very important for the design, simulation, and optimization of CO2 absorption in a packed column. In this study, two types of artificial neural networks (ANNs), namely back-propagation neural network and radial basis function network, were applied to predict the mass-transfer performance of CO2 absorption into aqueous monoethanolamine (MEA) in packed columns (containing Berl saddles, Pall rings, IMTP random packing, and 4A Gempack, Sulzer DX structured packing, respectively) from input variables. These variables were inert gas flow rate, liquid flow rate, solution concentration, liquid CO2 loading, CO2 mole fraction, temperature, and total packing area, which were considered to predict the targeted output mass transfer variables. The predicted results from ANN were validated against experimental data as well as compared with results from well-known correlations in terms of the volumetric mass flux, CO2 mole fraction, and temperature profiles al...

Performance optimization of tethered balloon technology for public safety and emergency communications

Abstract: This paper investigates the potential of a tethered balloon network architecture deployed as part of public safety networks and emergency communications. Tethered balloon technology has been evolving as a powerful and promising technology for improving public safety and for saving people’s lives. As such, it enables accomplishment of unique and specific missions for temporary events such as natural hazardous or terrorist acts. Such acts raise significantly the potential to disrupt the entire terrestrial wireless communication infrastructure. To mitigate the effects of such catastrophic events, we propose tethered balloon technology for delivering broadband services in an area over which the communication infrastructure has been entirely or partially destroyed. The results reveal a significantly high performance in providing broadband communication services with provision of Quality of Service. This suggests that the work of rescue and relief teams can be significantly enhanced.
