Abstract

Gas-solid mass transfer in the CO₂-naphthalene system was studied under subcritical to supercritical conditions. Theoretical and experimental mass transfer correlations for laminar flow in a packed bed are presented for the given experimental conditions (10–203 bar and 35–45°C) and are compared with those obtained at ambient conditions (1.01 bar and 25°C). Both natural and forced convection are found to be important but laminar natural convection is dominant at 100 bar and 45°C. Mass transfer is enhanced at supercritical conditions, largely due to strong natural convection effects caused by very low kinematic viscosities and large density differences across the boundary layer.

Mathematical modeling of mass transfer in supercritical fluid extraction of oleoresin from red pepper
2014, Journal of Food Engineering
Citation Excerpt :
Some mass transfer correlations for SFE can be found in literature (Ferreira, 1996; Lim et al., 1990; Puiggené et al., 1996; Mongkholkhajornsilp et al., 2005; Shi et al., 2007; Tan et al., 1988). The correlation of Lim et al. (1990) takes into account mixed convection, i.e., both natural and free convections are important. Although Ferreira (1996) used a similar consideration, her correlation considers a weak contribution of free convection in SFE represented by the small power of Grashof.
Supercritical fluid extraction (SFE) from red pepper (Capsicum frutescens) using CO₂ was performed in order to evaluate mass transfer. Kinetic extractions were done at 15 MPa and 40 °C, varying solvent flow rate, particle diameter and extraction bed volume. The highest extraction rates were obtained for high solvent flow rates, low particle diameters and low extraction bed volume. These results can be explained by the high importance of the convective phenomenon under these conditions. A classical model based on the concept of intact and broken cells was applied to experimental SFE curves, and model parameters were obtained. Two modeling strategies were used: (1) simultaneous fitting creating a set of parameters for pairs of duplicates, (2) multiple fitting that adjusts a single value for the solute concentration in unbroken cell for curves with equal particle diameter. These fits allowed estimating the convective mass transfer coefficient for each condition, and the respective values of the experimental Sherwood number. Experimental data was used to calculate dimensionless numbers of Reynolds and Schmidt for each condition. A second series of mathematical modeling was performed using these dimensionless numbers, which allowed proposing new mass transfer correlations. These new equations were based on the existence of forced and free convection, although the importance of the latter was small. The convective coefficients calculated with the correlations were compared to those obtained from the model, and a good coherence was found between both.
Biodiesel production using supercritical methanol/carbon dioxide mixtures in a continuous reactor
2011, Fuel
Fatty acid methyl esters (biodiesel) were produced by the transesterification of triglycerides with compressed methanol (critical point at 240 °C and 81 bar) in the presence of solid acids as heterogeneous catalyst (SAC-13). Addition of a co-solvent, supercritical carbon dioxide (critical point at 31 °C and 73 bar), increased the rate of the supercritical alcohols transesterification, making it possible to obtain high biodiesel yields at mild temperature conditions. Experiments were carried out in a fixed bed reactor, and reactions were studied at 150–205 °C, mass flow rate 6–24 ml/min at a pressure of 250 bar. The molar ratio of methanol to oil, and catalyst amount were kept constant (9 g). The reaction temperature and space time were investigated to determine the best way for producing biodiesel. The results obtained show that the observed reaction rate is 20 time faster than conventional biodiesel production processes. The temperature of 200 °C with a reaction time of 2 min were found to be optimal for the maximum (88%) conversion to methyl ester and the free glycerol content was found below the specification limits.
A theoretical study of dense gas extraction using a hollow fiber membrane contactor
2006, Journal of Supercritical Fluids
Hollow fiber membrane contactors offer several advantages over dispersed phase contactors for extraction of aqueous feeds, including higher interfacial area, absence of emulsions, no flooding at high flow rates, and no unloading at low ones. The use of these contactors with extraction solvents near or above their critical points is of particular interest, because such fluids provide a favorable distribution of many solutes, high mass transfer rates, and easy recovery of extracted solutes.
In this paper, we describe a theoretical study of acetone extraction from aqueous solution into supercritical carbon dioxide, with tube side CO₂ flow either with or opposed to the force of gravity. Buoyancy-induced flow in the CO₂ phase was important for large (1.8 mm inside diameter) but not small (0.6 mm i.d.) fibers, consistent with our expectation that such flow is more difficult to achieve when the characteristic length is small. The importance of buoyancy-induced flow decreased with increasing imposed fluid velocity, as forced convection masked the effects of free convection. For the range of conditions studied, the mass transfer coefficient obtained with flow in the direction of gravity was as much as 33% higher than with flow opposing gravity.
A study comparing the performance of traditional mass transfer equipment and hollow fiber membrane contactors is also described. Ethanol and isopropanol extractions performed by others using spray, sieve tray or packed columns were run on a simulated membrane contactor, and the resulting values for the height equivalent to a theoretical stage (HETS) were compared to the reported values for the conventional contactors. In most instances the simulated membrane contactor offered a significantly (in some cases, substantially) lower HETS than the corresponding traditional column, indicating that the membrane contactor was more efficient.
Dense gas extraction using a hollow fiber membrane contactor: Experimental results versus model predictions
2005, Journal of Membrane Science
Hollow fiber membrane contactors offer a number of advantages over dispersed phase contactors for mass transfer operations such as extraction of aqueous feeds. In addition, dense gases provide benefits that traditional extraction solvents do not. A mathematical model of a membrane contactor was developed that predicts the steady state fluid velocities and solute concentrations by solving the applicable conservation equations. The gravitational force term was included because the low kinematic viscosity of dense gases can render buoyancy-induced flow significant. A method of calculating the individual and overall mass transfer coefficients from the model results is also presented.
The model was validated by comparing predicted Sherwood versus Graetz numbers for tube flow to those obtained from the classical equations that have been repeatedly confirmed by experiment. The three boundary conditions examined were constant wall concentration, constant flux, and linear variation of wall concentration with length. For all three cases the model predictions were in close agreement with those of the classical equations over a wide range of Graetz numbers, except for the constant flux condition at Graetz numbers greater than about 1000. This exception reflects a limit on the mass transfer rate imposed by the constant flux boundary condition. Graetz numbers greater than 1000 (found with short tubes or very high velocities) are not usually encountered in practical applications. Model results are compared to experimental data for the extraction of isopropanol or acetone from water into dense CO₂, obtained over a range of flow rates using modules of different packing densities. Overall the model predicted the data reasonably well, proving the model to be a useful tool for evaluating potential new applications of the technology. For the isopropanol extractions the average absolute errors in the predicted mass transfer coefficients and yields were 29% and 31%, respectively, while for the acetone work the average absolute errors were 39% and 11%. In both cases the predicted mass transfer coefficients were lower than the observed values at the highest aqueous flow rates studied; usually the error became less negative (then increasingly positive in some instances) with decreasing flow rate. This trend is partly attributable to flow maldistribution (leading to reduced efficiency) caused by unavoidable non-uniform fiber spacing and variation in fiber diameter. Other possible sources of modeling error are discussed as well.
With acetone, most of the resistance to mass transfer was in the aqueous phase boundary layer, as expected for a solute with a relatively high partition coefficient (m_A). On the other hand, for isopropanol (a lower m_A compound) a greater portion of the resistance was attributable to the solvent-filled pore and the solvent phase boundary layer, although the aqueous resistance was still significant. Mass transfer coefficients and yields were higher for acetone than for isopropanol, and aqueous boundary layer penetration was more rapid; both results were a consequence of the higher m_A of acetone. For both solutes, usually the mass transfer coefficient increased with increasing aqueous phase Graetz number, as expected when the aqueous phase mass transfer resistance is important. Moreover, yield generally increased with increasing solvent/feed ratio as anticipated.
Solubilities of benzoin, propyl 4-hydroxybenzoate and mandelic acid in supercritical carbon dioxide
2002, Fluid Phase Equilibria
A semi-flow type apparatus was used to measure the equilibrium solubilities of benzoin , propyl 4-hydroxybenzoate, and mandelic acid in supercritical carbon dioxide at 308.15, 318.15, and 328.15 K over the pressure range from 9 to 24 MPa. New equilibrium data of solid solubility in supercritical carbon dioxide are presented. The approach to solid–fluid phase equilibrium is examined based on a plug flow fluid–solid mass transfer model. The Soave–Redlich–Kwong and the Peng–Robinson equations of state (EOS), with the van der Waals and the Huron–Vidal type mixing rules were used to correlate the experimental data. The solid solubility data were also correlated with density based semi-empirical equations of Chrastil, and Santiago–Teja. It is shown that these solid solubility data are correlated with reasonably good accuracy using optimally fitted parameters.
