How to use the Aspen Plus software to employ regression parameters based on CO2 partial pressure and CO2 absorption load in the process of capturing CO2 using the alcohol amine method

Do experts use the Aspen Plus software to input experimental data on CO2 load and CO2 partial pressure in order to determine regression parameters? After all, in the absorbent, CO2 exists not only in molecular form but also as HCO3- ions. I have converted the amount of these ions to an equivalent amount of CO2 – is this approach correct? The parameters obtained through regression are quite inaccurate; does anyone know what the problem might be? Thank you so much! !
