Patrícia F. Leal, +6 more
- 01 Jul 2010 - 
TL;DR: In this article, supercritical fluid extraction (SFE) with CO2 and low-pressure solvent extraction (LPSE) with methanol, hexane and ethanol were conducted at pressures of 100, 200 and 300 bar, and temperatures of 30 and 50°C.

Study of the phase equilibrium formed inside the flash tank used at the separation step of a supercritical fluid extraction unit

Thais M. Takeuchi, +6 more
- 01 Jan 2008 - 
TL;DR: In this paper, the influence of a non-ideal flash separation step of a supercritical fluid extraction (SFE) unit was studied; the solvent used was carbon dioxide, and the behavior of clove bud ( Eugenia caryophyllus), vetiver grass ( Vetiveria zizanioides ), and fennel ( Foeniculum vulgare ) was analyzed.
