How can “Instantaneous Pressure-Drop DIC” Texture Camelina Seeds, Increase Extraction Yields and Preserve Vegetal Oil Quality?
Global Advanced Research Journal of Engineering, Technology and Innovation (Volume : 6)
Texturing by “Instant Controlled Pressure-Drop” (DIC) used as pretreatment technique in both solvent and
pressing processes allowed getting higher yields and better kinetics with perfect preservation of quality of
Camelina-sativa seed vegetal oil. Response Surface Methodology (RSM) was used and led to optimize DIC
processing parameters of temperature (T) and time (t) at 158 ᵒC for 41 s. For both pressing and solvent,
yields were 0.3153 and 0.4490 g oil/g db (dry basis), which were 38% and 22%, respectively higher than the
yields issued from the crude Camelina seeds. In addition, the composition of vegetal oil issued from DICtextured
Camelina seeds was similar to the crude raw material oil, thus relating a good preservation of the
Swell-Texturing assisted in-Situ Transesterification of Camelina Seeds Biodiesel
International Journal Of Engineering Research And Development (Issue : 9) (Volume : 13)
Camelina seeds are a captivating source of vegetal oil, used for both food and industrial
applications. The current work aims at intensifying In-Situ Transesterification (ISTE) using swell-texturing by
Instant Controlled Pressure-Drop (DIC). This DIC swell-texturing produced twice more biodiesel (0.7731
against 0.39 35 g FAME/g ddb).
Coupling of Texturing/Cooling using Instant Controlled Pressure Drop and Transesterfication for Biodiesel Production from Camelina Sativa
Global Journal of Researches in Engineering: G Industrial Engineering (Issue : 2) (Volume : 17)
Although Camelina Sativa as oleaginous seeds has obvious advantages as a feed of
wonder health benefits, it has been recommended as a highly promising environmental
sustainable energy crop and a perfect source of biodiesel. The current work deals with the
industrial significance of intensifying the oil and biodiesel yield from Camelina seeds by
incorporation of a pretreatment stage for raw material texturing using Instant Controlled Pressure-
Drop (DIC) process. The texturing process proved to promote the yield of oils produced by
pressing the seeds, and extraction the seeds using solvent, by an amount of 75.9 and 82.9 kg oil
/1000 kg seeds, respectively compared to the raw untreated seeds.
SEPARATION AND SPECTROSCOPIC CHARACTERIZATION OF NPARAFFIN WAXES AND ISOPARAFFINS FROM THREE LOCAL CRUDES IN KURDISTAN REGION OF IRAQ
Journal of University of Zakho (JUOZ) (Volume : 1)
Samples of light, medium and extra heavy Kurdistan crude oils and have been de-asphalted and
separated into fractions of saturates by elution liquid chromatography technique. The fractions obtained
were separated into n-paraffins, isoparaffins by urea adduction and analyzed using FTIR spectroscopy.
The infrared data confirmed the presence of methyl and methylene groups in the saturate fractions of the
crude oils. Tawke paraffins fraction have the highest value of methyl index, while Jamjamal has the lowest,
it means that it has the longest chains of saturating hydrocarbon more than others, while Taqtaq
isoparaffins have the highest value, Jamjamal has the lowest.
Evaluation and improvement of gasoline and naphtha cut of Tawke crude oil wells, Zakho
Journal of Petroleum and Gas Exploration Research (Volume : 2)
Gasoline cuts have been separated from crude oil of Tawke wells (fourth and eighth) according
to ASTM method at one atmosphere. The physical properties of each gasoline have been determined.
Also chemical constituents of these gasolines have been examined using gas chromatography
and compared with Naphtha Tawke Refinery. Percent of each straight run gasoline from crude oil
of both wells have been determined with their Octane Numbers (RON and MON). The current
research has been performed to increase the Octane Number of both gasoline and Naphtha using
series of oxygenated and organometallic additives. Also, mixed additives of oxygenated and
organometallic have been added to this gasoline and Naphtha in order to find the enhancement
in Octane Number. These mixtures give more increases in Octane Number than pure oxygenated
or organometallic additives.
