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

Techno-economic evaluation of the extraction of turmeric (Curcuma longa L.) oil and ar-turmerone using supercritical carbon dioxide

“…The cost of raw material included the acquisition costs of turmeric rhizomes and CO 2 . The spending of CO 2 was calculated by the sum of the CO 2 lost during the extraction vessel decompression step (estimated by the simulator) and of the CO 2 that remains dissolved in the extract after the separation step (it was assumed as 2% of the CO 2 present in the mixture of CO 2 and extract; based on the work of Takeuchi et al [37]). Furthermore, the pre-processing cost of the rhizomes must also be considered by being added to the unit cost of the vegetable matrix.…”

Phase Equilibrium Measurements of Sacha Inchi Oil (Plukenetia volubilis) and CO2 at High Pressures

“…CO 2 were carried out using the static synthetic method in a high pressure variable-volume view cell. The experimental apparatus and procedure have been well described in previous studies [12][13][14]. The experimental unit consists of a 25 mL variable-volume view cell with two sapphire windows for visual observation, an absolute pressure transducer (Smar, model LD 301, Sertãozinho, SP, Brazil) with an uncertainty of ±0.03 MPa, a portable pressure data acquisition system (Smar, model HT 201, Sertãozinho, SP, Brazil), and a syringe pump (ISCO, model 260D, Lincoln, USA).…”

The Fatty Acid Profile and Phenolic Composition of Descurainia sophia Seeds Extracted by Supercritical CO2

“…Ethanol-assisted SC-CO 2 method has been reported for extraction of polyphenols from grape waste at much higher pressure (500 bar) compared to our extraction conditions [27]. Total phenols from passion fruit were also extracted at much higher ethanol addition of 23 % (wt%) and higher temperature (60 °C) [28]. Another important factor is the time, the co-solvent can be added at the beginning without having a pre-step of neat CO 2 extraction.…”
