Description
Summary:[Display omitted] •Equation-oriented rate-based steady state model developed for RPB stripper using MEA concentrated solution in gPROMS.•Proper thermodynamic, kinetic, transport, and hydraulic models are used.•Process analysis is done by assessing the influence of different parameters on desorption efficiency and desorption energy. Rotating packed bed (RPB) system has applications in CO2 removal using chemical solvents which can reduce the size about ten times compared to common packed bed (PB) system. In this study, RPB stripper using monoethanolamine (MEA) solution is modelled in gPROMS® software. The model has been validated using experimental data from literature and show good agreement. In addition to stripper modelling and validation, the process analysis is accomplished in this study by assessing the influence of four parameters namely rotor speed, reboiler temperature, flow rate of rich liquid, and pressure on desorption efficiency and desorption energy.
