“…They also measured high-pressure VLE for the CO 2 -limonene -linalool ternary system. [10] Furthermore, Akgun et al, [11] Viera de Melo et al, [12] and Chang and Chen [13] reported the VLE calculation focused on modeling high-pressure phase behavior for CO 2 -limonene and CO 2 -linalool using several different mixing rules. Further, an isothermal flash calculation was applied to investigate selectivity and yield for the ternary system CO 2 -limonene -linalool in order to understand the process parameters for the citrus oil processing by SC-CO 2 .…”

Phase behavior of limonene and linalyl acetate, which are principal constituents of terpenes and oxygenated compounds, respectively, in bergamot oil, with supercritical carbon dioxide (SC-CO 2 ) was observed by use of process simulator (SIMSCI PRO/II). Solubility of each pure component in SC-CO 2 was calculated by the Peng -Robinson equation of state. For a given calculating condition, the solubility of limonene was 2 -5 times higher than that of linalyl acetate. Process flow diagram for the citrus oil processing by SC-CO 2 extraction column was successfully constructed to evaluate the separation performance.The effects of feed composition, feed inlet position, reflux ratio, and stage number on the extraction ratio of limonene, separation selectivity, and recovery of linalyl acetate were studied at 333K and 8.8 MPa.

“…A knowledge of the solubility of the target compounds in the SCF is necessary in order to establish whether the compound can be solubilized or not by the supercritical fluids under given conditions. Several studies have reported the solubility of essential oils in SC-CO 2 (Akgün et al 1999;Raeissi and Peters 2005a, b;Sovová et al 2001).…”

This review provides an updated overview of the most important applications of supercritical fluids in the extraction of bioactive compounds from plant matrices. The main factors influencing the extraction yields, solubility, and manufacturing costs are described. Aspects concerning the operational processing in the extraction and fractionation are also discussed. The data compiled herein are focused on the extraction of essential oils, phenolic compounds, carotenoids, tocopherols, and tocotrienols.

“…Several authors showed that Peng-Robinson (PR) EoS can be used to describe the phase behaviour of carbon dioxide and terpene oils [24][25][26][27]. Due to its versatility and simplicity, PR-EoS was chosen to represent the binary system CO 2 /Limonene.…”
