How to simulate perry ch.13 example 5: two-step absorber with intercooling
Two absorption stages in series with intercooling between them (removing the heat of absorption, which otherwise raises K-values and hurts recovery) to maximize LPG recovery, from Chapter 13 of Perry's Chemical Engineers' Handbook.
- 1Open the ready-made model
Open the "Perry Ch.13 Example 5: two-step absorber with intercooling" model in the MaximaLabs workspace — no install, no license. It loads live on the canvas, ready to edit and run.
- 2Confirm the thermodynamics
This process is modeled with the PENG-ROBINSON property package over methane, ethane, propane, n_butane, n_pentane, n_dodecane — already selected, so the phase equilibrium and enthalpy are physically consistent from the first run.
- 3Review the flowsheet
The flowsheet chains 2× ABS B, Intercooler. Every block is a real, solvable unit op you can reconfigure on the canvas.
- 4Run the simulation
Click Run. The deterministic solver converges the material and energy balances (recycles included) and fills the live stream table — the AI never invents a number.
- 5Read the results and iterate
Inspect the converged streams, tweak a spec, and re-run — or ask the AI copilot to explain a result or diagnose a failed solve in plain English.

- What does the Perry Ch.13 Example 5: two-step absorber with intercooling model simulate?
- Two absorption stages in series with intercooling between them (removing the heat of absorption, which otherwise raises K-values and hurts recovery) to maximize LPG recovery, from Chapter 13 of Perry's Chemical Engineers' Handbook.
- Which thermodynamic method does it use?
- The PENG-ROBINSON property package, over methane, ethane, propane, n_butane, n_pentane, n_dodecane — already selected. You can switch the method on the canvas before running.
