Simulated Moving Bed Simulation with CADET

This repository contains example simulations of Simulated Moving Bed (SMB) processes using CADET-Process and CADET-RDM. A four-zone SMB system with eight columns and a five-zone SMB system with five columns are examined. A linear binding model and an Equilibrium-Dispersive Model (EDM) are used to simulate binary and ternary separations. The EDM is solved by adapting the General Rate Model (GRM).

This example reproduces part of the case study from:

Running the Example Simulation

1. Clone this repository.

2. Set up the environment using the environment.yml file.

3. Run the simulation:

   python main.py

The results will be stored in the src folder inside the output directory.

Note: Running cadet-rdm requires Git LFS, which needs to be installed separately.

• Ubuntu/Debian:

  sudo apt-get install git-lfs
  git lfs install

• macOS (with Homebrew):

  brew install git-lfs
  git lfs install

• Windows: Download and install from https://git-lfs.com
