GoSpAXI: Open-Source PSA System Design Optimization

An open-source software platform for computational design and optimization of gaseous separation processes, including pressure swing adsorption (PSA) systems for applications like hydrogen purification, air separation, and carbon capture.

What is GoSpAXI?

GoSpAXI is an open-source software tool developed by the Gas Separations Group at the Georgia Institute of Technology for the design and optimization of adsorption-based separation processes. It focuses specifically on pressure swing adsorption (PSA) systems, which operate by cycling adsorbent beds through pressurization, adsorption, depressurization, and desorption steps to separate gas mixtures.

Some key features and capabilities of GoSpAXI include:

• Rigorous PSA process modeling based on detailed adsorption equilibrium and kinetics
• Optimization of PSA cycles and operating conditions for objectives like product purity, recovery, and power consumption
• Equipment sizing and cost estimation modules
• Integration of real adsorbent characterizations into process models
• Graphical workflow to link simulation, optimization, and analysis

GoSpAXI simplifies PSA modeling and allows quick evaluation of the trade-offs between multiple performance metrics. It can be applied to simulate and optimize systems for a wide range of gas separation applications such as hydrogen purification, air separation, natural gas upgrading, landfill gas cleanup, and carbon capture. The open-source nature also enables customization and integration with other tools.
