Selective Recovery of Fluorinated Gases from Refrigerants Using Ionic Liquids

Six fluorinated gases and three quaternary phosphonium-based ionic liquids are studied for gas absorption. The dataset, authored by B. González-Barramuño and last updated in May 2026, contains model outputs for solubilities, Henry's constants, and competitive absorption from five commercial refrigerant blends. It is a 45.7 KB ZIP file shared under a CC-BY-NC-4.0 license.

Use Cases

• Predicting gas solubility in ionic liquids based on the soft-SAFT equation of state model.
• Assessing competitive absorption selectivity for commercial refrigerant blends like R410A and R451A.
• Calculating thermodynamic properties such as enthalpy and entropy of dissolution for process design.
• Evaluating ionic liquid performance for separating lower-GWP components from near-azeotropic mixtures.

Strengths

• Modeling results for six specific fluorinated gases and three specific ionic liquids.
• Analysis includes five commercial refrigerant blends over a range of temperatures and pressures.
• Uses two established computational methods: COSMO-RS and the soft-SAFT equation of state.

Limitations

• Row count and specific column-level documentation are absent; field semantics must be inferred after download.
• The dataset is small at 45.7 KB, indicating limited scope.
