A medium-order dynamic model was developed in gPROMS® for an intercooled CO2 absorber column with piperazine solvent. This model represents an improvement from previously published rate-based dynamic models because it uses a regressed eNRTL thermodynamic package and a liquid film mass transfer coefficient with an experimentally measured CO2 loading dependence. Off-design simulation results were validated...
High operating cost and significant decrease in net power generation are major barriers to the implementation of post- combustion amine scrubbing for CO2 capture from coal-fired power plants. To improve efficiency and make the process more attractive economically, alternative process configurations and second generation solvents are being investigated. Dynamic modeling can be a useful tool in understanding...
This paper presents steady state and dynamic modelling of post combustion CO 2 capture using 30 wt% MEA integrated with models of CO 2 compression and the steam power cycle. It uses multivariable optimization tools to maximize hourly profit of a 100 MWe coal-fired power plant. Steady state optimization for design provided optimum lean loading and CO 2 removal as a function...
