Process simulation and economic analysis of biodiesel
Lim et al. (2009) conducted economic analysis of the processes for supercritical biodiesel production from rapeseed oil and compared its profitability to an alkali-catalyzed process. They found that the total manufacturing cost of the supercritical process was lower than the alkali-catalyzed process due to the absence of catalyst and higher by
Heavy oil and supercritical water were supplied by counterflow in a 1/2-inch diameter tubular reactor filled with 3 mm diameter Al 2 O 3 particles; pressure and temperature were set at 25 MPa and 400 °C. The authors found that the behavior of heavy oil in supercritical water depended on the flow rate of oil and water.
Supercritical fluids in separation and purification: A review
Commercialization of biodiesel oil production using newer extraction techniques is gaining importance. Scientists have used supercritical fluids for the production of biodiesel. Macaria et al. [123], studied biodiesel production in a continuous reactor with the extraction solvent being a mixture of supercritical methanol and carbon dioxide.
To this end, a pilot scale plant for the continuous production of biodiesel in supercritical conditions was designed, manufactured and operated. In this research paper, rapeseed oil and bioethanol were used as raw materials, and the investigated temperatures were between 200 and 340°C, the pressure between 150 and 240 bar, and the alcohol-to
Supercritical Fluid Extraction: A Global Perspective of the
where m EXT is the mass of the extract (kg), t is the time of extraction (s), N is the number of straight lines, b 0 is the linear coefficient of line 1 (kg), ∑a i (for i = 1 to i = N) are the slopes of lines 1 to N (kg/s), and t i (for i = 1 to i = N1) is the time in which the intercept between line “i” and line “i + 1” occurs (s).
Biodiesel, which is derived from renewable feedstock, has potential to replace fossil diesel. In this study, biodiesel production was carried out through the transesterification of soybean oil with ethanol (anhydrous and hydrated) under supercritical conditions in a batch reactor, with a temperature range of 280–340 °C and an oil/alcohol molar ratio of 1:40. The effects of both anhydrous

Non-catalytic biodiesel fuel production with supercritical
Experiments with transesterification of rapeseed oil in supercritical alcohols (methanol, ethanol and 1-propanol) were carried out in a batch reactor at various reaction temperatures (250-350 °C
The supercritical-microreactor technology was applied to accelerate both mass transfer and kinetic rates of biodiesel production. The ester content of 75% in biodiesel was obtained at the reaction temperature of 300 °C and the residence time of 24 min.
- Why are supercritical fluids used in oil & gas production?
- Supercritical fluids find use in various areas in oil and gas production operations due to their unique properties. Supercritical CO 2 (sc-CO 2) with its reduced viscosity, increased diffusivity, and liquid like density, is attractive for enhanced hydrocarbon recovery, shale gas fracturing and drilling (especially in underbalanced condition).
- Could supercritical fluids be a breakthrough technology in oil production & refining?
- Technologies based on the use of supercritical fluids could become one of the breakthrough technologies in oil production and refining. Supercritical fluid (SCF) is a state of matter in which the difference between the liquid and gas phases disappears [ 1, 2, 3, 4, 5, 6, 7 ].
- Which stage has the fastest oil production?
- Experimental results show that the gas breakthrough stage has the fastest oil production and the supercritical CO2injection capacity variation tendency is closely related to the gas¨Coil ratio.
- Can supercritical CO2 be used in oil and gas industry?
- Therefore, based on the conducted review, one can conclude that using supercritical CO 2 in the oil and gas industry looks very promising. This is evidenced by a large number of publications on this topic carried out in the recent decade.
