“…Many studies evaluate the economic feasibility of biodiesel production plants from process simulations. ,− In these studies, the biodiesel process commonly includes a step consisting of a three-phase separator to isolate the light liquid phase (rich in biodiesel) from the heavy liquid phase (rich in glycerol). ,,− In this context, a good description of the LLE is essential for the reliability of the results obtained for the equipment in the process simulator. ,, However, the binary molecular interaction parameters A ij 0 and A ji 0 required by the selected activity coefficient model in the simulation are commonly estimated using the group contribution method UNIFAC, which is available within the process simulator. This is done instead of using the parameters obtained through a thermodynamic modeling of the LLE experimental data.…”

Liquid–liquid equilibrium (LLE) for the biodiesel + glycerol + alcohol system is essential for the design, operation, process optimization, and economic evaluation of a biodiesel production plant. In this work, methyl and ethyl safflower biodiesels were produced from safflower (Carthamus tinctorius L.) seed oil. New LLE experimental datasets were obtained for the glycerol (1) + methanol/ethanol (2) + methyl/ethyl safflower biodiesel (3) systems at 298.15 and 318.15 K under atmospheric pressure. Binodal curves, tie-lines, distribution coefficients, and selectivity were determined. Data reliability was confirmed using the Othmer–Tobias correlation. LLE data were correlated with the UNIQUAC model satisfactorily, with deviations between 0.70 and 2.79% for all studied systems. The consistency of the estimated binary interaction parameters of the UNIQUAC model was ascertained. Finally, through process simulations in Aspen Hysys software, it was verified that the UNIFAC LLE model, along with the UNIQUAC model, can also be used adequately to describe the liquid–liquid behavior of biodiesel separators, provided that the biodiesel composition is accurately known.

“…While fossil fuel resources are limited, the increasing demand for energy in the industrial and transportation sectors has led to the use of renewable fuels. [ 1–3 ] Biodiesel is the most widely used form of renewable fuel and is commonly recognized as FAME, which stands for fatty acid methyl ester. [ 4 ] Biodiesel is a monoalkyl ester of long‐chain fatty acid produced from the reaction of triglycerides with alcohol such as methanol or ethanol in the presence of a catalyst.…”

While fossil fuel resources are limited, the increasing demand for energy in the industrial and transportation sectors has led to using renewable fuels. This study aims to improve biodiesel production from sunflower oil by combining cold plasma and oscillatory systems through a transesterification process. The four main operational variables are examined, such as molar ratio (MR) (1:6–1:12), catalyst concentration (CC) (0.5–1.25 wt%), plasma exposure time (PET) (25–75 s), and residence time (RT) (30–90 s). The smooth periodic constriction reactor's physical attributes, including the diameter of the tube (D), the diameter of the constricted region (d0), and the distance between baffles (l), as well as the properties of the cold plasma system, are determined. The data analysis presents that PET, RT, CC, and MR have the greatest effect on efficiency. This optimization indicates that by exposing the reaction mixture to plasma for 59.99 s, adding 1.09% by weight of the catalyst, and with a MR of 7.17 in 86.43 s, biodiesel with a conversion percentage of 94.75% is produced. The results show that the optimum point matches with EN 14214 standard.

“…Polyvinyl alcohol nanoparticle suspension was successfully produced with uniform size distribution of nanoparticles and a high extraction efficiency close to 100%. Additionally, increasing the number of microchannels was proposed to be easy in the microfluidic system, where the same quality of products between the industrial scale and experimental scale could be achieved. , Although the micro-flow system was applied to SFEE for nanoparticle production in these literature studies, the emulsion for SFEE was prepared by the batched stirring of oil and water phases. The integration of emulsification and SFEE in the micro-flow system is preferable to reduce the procedure of the production, from several batches to one-step flow, and achieve the complete flow production.…”

Combination of micro-flow processes between emulsification and supercritical fluid emulsion extraction was applied for the fabrication of stearic acid lipid nanoparticles dispersed in aqueous solution. Controllability of the lipid nanoparticle production by the flow rate of oil and water phases, surfactant species, surfactant concentrations, and pressure was investigated. The utilization of two different surfactant species was considered for the stabilization of oil droplets and solid lipid nanoparticles in water. As a result, Tween 80, a hydrophilic surfactant, was revealed to have an important role in obtaining a homogeneous emulsion phase, which is necessary to control particle sizes after the extraction process. Additionally, lecithin, a hydrophobic surfactant, successfully narrowed the size distribution of solid lipid nanoparticles, which can be explained by the suppression of their aggregation. Furthermore, the extraction efficiency values were over 97% and the model active ingredient was successfully encapsulated in the particle structure. These results suggest that combination of surfactant systems in the integrated micro-flow process is an appealing approach to continuously fabricate stable and uniform solid lipid nanoparticles for practical applications.
