CHAPTER 17

Gas Expanded-liquids

In this chapter, the potential use of gas-expanded liquids (GXLs) is presented, highlighting the applications of those that employ carbon dioxide to modify the chemical and/or physical properties of the solvents. Some fundamentals and properties of carbon dioxide-expanded liquids (CXLs) are described, as well as how these properties can be modified as a function of the pressure, temperature and percentage of CO2 in the mixture. Moreover, some new applications related to separation science (including extraction, precipitation and oil recovery) are also presented and discussed. The possibility of using these new types of solvents opens the door to the development of more sustainable chemical and technological processes that can contribute to the planet's sustainability.
