Question about using ELECNRTL or ELECNRTL-RK for co2 capture simulation?

02 December 2024 0 8K Report

Hi,

I confused about what the best to use in aspen for simulation for co2 capture is ELECNRTL or ELECNRTL-RK?

I validated my model when I used ELECNRTL with two experimental and average percentage of error was less than 7 % .

The second question I want introduce some modifications to stripper to reduce energy consumption but may be I will use the equilibrium reaction for stripper only in order to reduce complexity while the absorber will involve both kinetic and equilibrium . is that acceptable?
