Development of a Tool for Estimating the Life Cycle Climate Performance of MAC Systems

Design of Ionic Liquids for Fluorinated Gas Absorption: COSMO-RS Selection and Solubility Experiments

“…F-gases account for 3.0% of greenhouse gas emissions in 2019. , However, these gases have a global warming power up to 23 000 times higher than CO 2 and an atmospheric lifetime up to 50 000 years . These gases are widely used in aerosols, refrigeration systems, defoamers, and in the air conditioning equipment of more than 80% of the world’s commercial vehicles. , In addition, in the European Union, about 19 million refrigeration equipment each year have completed their life cycle, generating uncontrollable F-gas emissions of approximately 26 million tons of CO 2 equivalent. , These emissions are mainly due to the state of the equipment, operating leaks, and the mismanagement that is being given to this equipment after completing its life cycle. , The effect on climate change of these gases is proportional to the amount emitted. As a consequence of emissions, the degradation of F-gases (e.g., the decomposition of the fluorocarbons HFC-134a, HCFC-123, and HCFC-124) in the atmosphere generates harmful byproducts, such as trifluoroacetic acid (TFA) or HF. , These compounds are persistent to natural degradation processes and are released into the environment by precipitation. − TFA acidifies water, is highly toxic upon accumulation in the ecosystems, can irritate tissues, skin, and could have an impact on human health. − Therefore, efforts to mitigate the impacts of F-gases must be prioritized, seeking alternatives based on sustainable processes for the capture, recovery, and recycling of F-gases.…”
