Supercritical Fluid Technologies, Inc. develops innovative solutions for demanding separation and material processing needs. With more than two decades of experience, SFT provides cutting-edge equipment and custom solutions to meet your specific needs in supercritical fluid extraction, reaction chemistry and high pressure applications. Supercritical fluid – the state of matter resulting when a gas is compressed above its critical temperature and pressure – has the solvating power of a liquid and the diffusivity of a gas. Fluids Supercritical Fluid Extraction employs a supercritical fluid, most commonly CO 2, as the A mobile phase solvent for the extraction. The intrinsic low viscosity and high diffusivity of supercritical CO 2 has rendered SFE a faster extraction and higher efficiency technique when compared to traditional liquid extraction.

Se hela listan på supercriticalfluid.org 2020-01-29 · Carbon dioxide supercritical fluid extraction (CO 2 SCFE) is free of the defects inherent in the methods otherwise employed to extract nutrients from algae – solvent extraction and pyrolysis. These leave behind solvent residues in the extract while also causing its thermal degradation [1]. Supercritical Fluid Extraction SFE systems are an alternative to the classic separation systems like fractionated distillation, steam current distillation, solvent extraction or thermal desorption. SFE can be applied to systems of all scopes and sizes , from test-lab to industrial scale: Feb 22, 2009 A powerful characteristic of supercritical fluid extraction (SFE) is the ability to precisely control which component(s) of a complex matrix are Supercritical Fluid Extraction (SFE) Systems.
