“…Before the extraction, the plant material was ground using a laboratory mill and sieved for 20 min using a vertical vibratory sieve shaker (LabortechnikGmbh, Ilmenau, Germany). The average particle size was determined to be 0.274 mm +/-0.068 according to the procedure given in our previous paper [13]. All measurements were performed in triplicate.…”

Extraction of rutin from Ruta graveolens L. leaves was performed in choline chloride based deep eutectic solvents (DESs). Firstly, rutin extraction was performed in five different DESs; pure DESs and with different amounts of water added (25% and 50% v/v), for different times (1 h, 3 h and 6 h) in order to find the best DES for further optimization. Choline chloride plus citric acid (1 : 1) was shown to be best DES and optimization of rutin extraction was performed using response surface methodology (RSM) based on the selected solvent and applying different extraction parameters: extraction time, temperature and water content.The rutin content was determined by HPLC and varied from 0.55 g/100 g of plant to 1.81 g/100 g of plant depending on the applied conditions. The best conditions for rutin extraction were found to be: a temperature of 70°C, an extraction time of 52 min and a water content of 27 % for the extraction of 1.88 g /100 g plant.

“…Parameters such as temperatures, pressures and flow rates of fluid need to be monitored and controlled in order to enable the efficient and economical extraction process. Due to the fact that the aforementioned parameters affect the extraction yield and the quality of the extract [9], these parameters need to be controlled and monitored with high precision. Since the process of SFE has been used on industrial scales for decades, the constraints on regulation and control are now well known.…”

Supercritical CO2 extraction pilot plant design - towards IoT integration

Preliminary communicationThe interest in high pressure technology during last decades increased intensively. Supercritical Fluid Extraction (SFE) is a process that is growing in importance as an alternative to conventional separation processes. SFE uses environmentally friendly CO2 as the extracting agent in the process because of its relatively low critical pressure (7,38 MPa), its low critical temperature (304 K), its non-dangerous character and low cost. During this process it is necessary to use high pressures in the procedure. The extractor vessel (pressure vessel) is the most important equipment of the system, where the supercritical conditions need to be established and the extraction occurs. Also other devices (separator vessel, heat exchangers, valves etc.) are necessary to be involved in the process due to used high pressures. Safety is the most important factor while dealing with SFE systems and the design of such equipment with full safety of process is very hard task. Therefore, to achieve the high desired safety level, a reliable control system must be designed as the control system and data communication segment. Various different process parameters such as CO2 mass flow rate, extraction pressures and temperatures affect the extraction process and the quality of the extract; hence these parameters need to be precisely controlled and monitored during the extraction. A design of one supercritical CO2 extraction laboratory-pilot plant and development of a remote control and its supervision system is presented in this paper. The developed SFE system (mechanical and electrical components) was compared with the existing commercial systems and its main advantages over the existing systems are presented. By enabling remote control and supervision the classical process control is joined with the concept of Internet of Things (IoT), where the information becomes omnipresent in the vast realm of Internet.Keywords: embedded system; process control; supercritical fluid extraction; system construction. Projektiranje pilot postrojenja za ekstrakciju superkritičnim CO2 -prema integraciji s Internetom objekata (IoT)Prethodno priopćenje Interes za tehnologije visokog tlaka tijekom posljednjih desetljeća se intenzivno povećava. Ekstrakcija super kritičnim fluidima (SFE) je process koji predstavlja alternative konvencionalnim postupcima separacije. U procesu ekstrakcije superkritičnim fluidima koristi se ekološki CO2 kao ekstrakcijsko otapalo zbog relativno niskog kritičnog tlaka (7,38 MPa), niske kritične temperature (304 K), poželjnih svojstava i niske cijene. Tijekom ovog postupka, potrebno je rabiti visoke tlakove. Ekstrakcijska posuda (posuda pod tlakom) je najvažnija oprema sustava, gdje se trebaju ostvariti kritični uvjeti i gdje se odvija ekstrakcija. Također, u procesu se treba obratiti pažnja i na druge dijelove uređaja (separator, izmjenjivače topline, ventile i sl.) zbog uporabe visokih tlakova. Sigurnost je najvažniji factor kada se radi o SFE sustavima i projektiranje takve opreme s potpunom sigurnosti ...

“…[1][2][3] Supercritical CO 2 extraction as a replacement of organic solvents in soybean oil extraction was considered in the last years by few researchers. [3][4][5][6][7][8][9][10][11][12][13] It has been proven that the oil extracted from soybeans with supercritical CO 2 is much higher quality than the same oil extracted by hexane. Furthermore, the refinement stages are simplified significantly and the solvent distillation stage is completely removed.…”

Abstract. Soybean oil fractions were obtained by collecting extract at different time intervals during supercritical CO 2 extraction. Relationships between retention behavior of seventeen TAGs and their molecular characteristics were studied using chemometric approach. Quantitative structure-retention relationship (QSRR) analysis was carried out on retention time values (t r ) obtained by high pressure liquid chromatography to identify structural requirements of different TAGs for their retention. Principal component analysis (PCA) was performed in order to select molecular descriptors that best describe retention behavior of the compounds investigated, and to determine the similarities among molecules. The accurate mathematical models were developed for predicting the retention behaviour of some TAGs. The validity of the models was evaluated by suitable statistical and cross-validation parameters.
