Suitable crude oils which can be treated with the additive according to the invention include heavy and extra heavy crude oils having a viscosity of at least about 103 cP at 25° C. and an API gravity of less than 20°. 7 show viscosity behavior of the tested samples at different temperatures, and the best results are shown with the additive in accordance with the present invention. Venezuela has a large supply of heavy and extra heavy crude oils which would greatly benefit from the improvement in viscosity and the inventors have found that the saponins which can be obtained in significant quantities from the native tree are well-suited toward the improvement of viscosity. Since many phytochemicals can dissolve in many solvents of different polarities based on their chemical structures, what is the best solvent or solvent mixture for extracting flavonoids from a plant leaves? The most common sources of saponins are the higher plants. It has high skin penetration value as compare to other vegetable oil. Further, the additive used to make this improvement in viscosity is environmentally friendly and it is derived from a locally readily available source. A viscosity reducer based on vegetable extracts of natural origin is disclosed. 2b shows an extra heavy crude oil with a saponin additive in accordance with the present invention, and very small air bubbles are shown which is indicative of low surface tension; FIGS. 10:67–83 (1993). Am. Meirelles, Viscosities of Fatty Acids, Triglycerides, and Their Binary Mixtures, J. Oil Chem. No aromatic base solvents are needed. What are your suggestions? 2a and 2b, where FIG. The saponins of interest are glycosidic natural plant products, composed of a glycone to which is attached one or more glycosidic chains. Even more accurate and simpler correlations could be derived. - S+H 16x288mm, F8T5/BLB 8W blacklight blue. Higher accuracy was also achieved when relating viscosities to volume fractions rather than to weight or mole fractions. This is a preview of subscription content, log in to check access. Am. Unfortunately each essential oil has a different viscosity (thickness or thinness) and this allows some of them to ‘pour’ out more quickly or terribly slooooowwwwwww. 2a shows an image of an extra heavy crude oil without the additive of the present invention and shows signs of very high surface tension; FIG. 2a shows a high surface tension extra heavy crude oil prior to treatment with the additive in accordance with the present invention, and FIG. The ethanolic extract can be evaporated under reduced pressure and crude saponin is obtained. 3 and 4 illustrate the FT-IR spectra of an extra heavy crude oil without additive and with additive in accordance with the present invention, respectively; FIGS. The viscosity of the extra-heavy crude oil is reduced by 5-10 times through the addition of 0.5 to 10% wt. Irving, J.B., Viscosities of Binary Liquid Mixtures: The Effectiveness of Mixture Equations, NEL Report No. Data 39:298–301 (1994). When it comes to lubrication, an oil's viscosity is considered the most important parameter. Volatile Constituents Isolated from Capparis flexuosa of Brazil. The torque of each sample at different temperatures was recorded at different shear rates. Heating the crude oil to temperatures of 50° C. and 60° C. also reduces the viscosity, but the level is still very high. Transportation of extra heavy oil outside of the well typically requires that the crude oil be heated or blended with diluents (BTX, light oils and kerosene) to reduce viscosity, or that the oil be upgraded on site, prior to transportation. Goodrum, Density and Viscosity of Low-Molecular Weight Triglycerides and Their Mixtures, J. Then, the unsaturated fatty acid is added, the mixture is homogenized and then added to 2% w/w of saponin extract is added. It depends on which herbal oil it is and check due to which reason viscosity is higher. © 2004-2020 FreePatentsOnline.com. Another way to obtain the crude saponin is by simple extraction with ethanol at room temperature and pressure; but more time is needed to evaporate. Gapinski, R.E., I.E. A method for increasing mobility of a heavy crude oil includes mixing an additive containing saponins and fatty acids with a heavy crude oil, wherein the saponins are derived from, BACHMAN & LAPOINTE, P.C. The ethanolic extract contains crude saponin or unpurified saponin. Thus, in accordance with the present invention a method is provided for increasing mobility of a heavy crude oil comprising the steps of mixing an additive containing saponins and fatty acids with a heavy crude oil, wherein the saponins are derived from Sapindus Saponaria. This technology includes methods and compositions to facilitate the transportation and combustion of highly viscous hydrocarbons by forming reduced viscosity hydrocarbon in water emulsions, and in particular, bioemulsifier stabilized hydrocarbon in water emulsions. The main identified products are (E)-2-hexenal (16.8–19%), β-caryophyllene (10.7-13.3%), 1,8-cineole (9-10%), myrcene (5-7%), and linalol (4-5.4%). Part of Springer Nature. A study was carried out to determine the effect of higher shear rates (64.5 to 4835 s−1) on the absolute viscosities of different vegetable oils at different temperatures (26 to 90°C).
