Request for Aspen Plus Triamine (MEA + MDEA + PZ) CO2 Absorption Model (.bkp) or Guidance

Dear Aspen Plus community,

I am currently working on simulating a CO2 capture process using Aspen Plus involving a triamine solvent system composed of MEA, MDEA, and Piperazine (PZ). I have successfully developed models for single amine and binary amine systems, but I am now looking for a complete and validated triamine absorption–regeneration process model, preferably a `.bkp` file that includes:

- Accurate thermodynamic property models (ENRTL-RK or ELECNRTL) for the MEA + MDEA + PZ + CO2 + H2O system,
- Rate-based RadFrac absorption and regeneration columns with appropriate kinetics,
- Typical operating conditions for industrial CO2 capture (e.g., 30 wt% total amines, flue gas composition, temperatures, pressures),
- Any existing validation data or references.

If anyone has developed such a model, or can share existing `.bkp` files, case studies, or detailed parameter settings, I would greatly appreciate it. Additionally, any advice on how to effectively extend binary amine models to triamine systems is also welcome.

Thank you very much for your help!
