Supercritical Fluid Technology: Patel Parth: Amazon.se: Books

The supercritical fluid commonly utilized is carbon dioxide (CO2). The state diagram of CO2 visualizes the various phases (solid, liquid, gas) depending on pressure and temperature. CO2, at 31,1°C and 73,8 bar, is in its supercritical state, in which there is no distinction between liquid and gaseous phases (as shown in the following picture). Supercritical Fluid Extraction employs a supercritical fluid, most commonly CO2, as the A mobile phase solvent for the extraction. The intrinsic low viscosity and high diffusivity of supercritical CO2 has rendered SFE a faster extraction and higher efficiency technique when compared to traditional liquid extraction.

Supercritical fluid co2

2020-1-29 · 1. Technical Overview 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 … The productivity and profitability of a supercritical fluid extraction (SFE) process largely depends on the selection of process parameters, which are elaborated upon in this paper. Carbon dioxide (CO2) is the most desirable solvent for the supercritical extraction of natural products.

Extraction - Kovalent AB

Carbon dioxide and water are the most commonly used supercritical fluids, as they are used for decaffeination and power generation, respectively. In general terms, supercritical fluids have properties between those of a gas and a liquid. The critical properties of some substances used as solvents and as supercritical fluids are shown in Table 1 In the supercritical extraction process, the carbon dioxide is first subcooled in order to guarantee the liquid phase before entering into the pump to avoid cavitation. Then the pressurized CO 2 is heated above its critical temperature, while the extractor is maintained at the operating temperature through electricity or hot water.
