Mohanty, V (2014) Simulation of methyldiethanolamine-carbon dioxide-water system
using equilibrium approach. BTech thesis.
As the climate is changing very frequently and global warming is increasing at an alarming rate, there is a need to mitigate greenhouse gases which have gained a top most priority. As the main source of CO2 emission is fossil fuels (mainly in power plants), there is a need to keep check on utilization of fossil fuels. Carbon capture and sequestration (CCS) is one of the methods which enable the utilization of fossil fuels with lower CO2 emissions. Commercially CO2 capture by chemical absorption is very active. While number of solvents for CO2 absorption by chemical method has been proposed, comparison on performance of different solvents has not been done properly and claims on different solvent vary widely. The work done here emphasize on absorption of CO2 by the solvent and then stripping the solvent to obtain pure CO2.This thesis has been prepared to evaluate the performance of solvent – methyldiethanolamine(MDEA) on CO2 absorption. In this thesis, comprehensive flow sheet model has been built for the solvent system, using ASPEN Plus as the modeling tool. The Thermodynamic model using ENRTL model for CO2 capture has been done and effect of reboiler duty, solvent flow rate and so on has been observed.
