 The accuracy in measuring the physical properties of any crude oil has become a very difficult task because the price of crude oil in the global market depends on it in addition to the process of producing lubricating oil , chemical products and refinery. Accordingly, this research effort focuses on comparative study of Libyan crude oil (El-Wafa field)  by measuring the physical and some chemical  properties  experimentally and by Aspen HYSYS V8.4 programs. Also, test the possibility to know the volume percentage of the production of lubricants from this crude oil by the two methods mentioned above.Test carried out on these measurements practically and theoretically the physical properties are include: normal boiling point, pour point, Specific gravity (Sp. gr.), standard density (API), dynamic viscosity , kinematics viscosity , molecular weight, Acentric factor and Watson factor (K or Kw ). Some chemical properties have also been experimentally measured, for example the sulphur content ( wt.%), Asphaltenes content( wt.%)  , water and sediment content (vol.%), Conradson carbon residue ( wt.%) , salt content (as NaCl, mg\L),  ash content(wt. %) and metals content ( wt.%).The results from the tests showed that, there is a very small convergence between the results of calculations of physical properties by use this modern software with experimental measurements in the lab to the crude oil of El-Wafal field up to 99% and this blend is not suitable for production the lubricated oil at atmospheric distillation column. Also, the results observed that’s the useful mole percentage of lubricated oil cutoff has volume percentage range not significant from 1 to 1.8% for this type of Libyan crude oil. Through practical and theoretical results possible to classify this type of crude oil as Brent mix according to the global market for the sale of crude oil, which is characterized by its lack of sulfur element and metals in addition to its standard relative density API is very high more than 55.

Abstract One of the most important oil derivatives in our time, which all the world seeks to obtain and produce a lot is lubricating oils, which are used for several important purposes and the most important is to keep the thermal engines from damage or collapse due to the phenomenon of friction of the moving parts mechanically at a high temperatures and pressure is relatively high as well as the wear phenomenon This research effort focuses on a comparative study of five types of mix crude Libyan oils (El-Feel Field, Al Wafa Field, Amina Field, Brega Field and Al-Sedra Field) for produced the lubricated oil experimentally . Test carried out on the production the lubrication oil by measuring the physical properties include: normal boiling point, pour point, specific gravity (Sp. gr.), standard density (API), dynamic viscosity , kinematics viscosity , Acentric factor and Watson factor (K or Kw). It’s found from the practical results of the production the lubricating oil from crude oil for atmospheric distillation of crude oil practically depends on measurement two physical properties very accurately Watson factor first and then the API. The results from the tests showed that, mix crude oil of Amena, El-Sedra and El-Feel fields suitable than others for production the lubricated oil at atmospheric and then use the vacuum distillation columns. Other results observation, that’s two others types are impossible to produce the lubricated oil. Also, the results observed that’s the useful mole percentage of lubricated oil cutoff has range very small from 2 to 17 % for these types of Libyan crude oils, this percentage will be increase when use vacuum distillation with added some additives materials. In addition, practical results have been found that not all the cutoff produced from atmospheric distillation within the range of temperatures between 370 and 550 oC are lubricating oils, but other compounds are oil derivatives suitable for different fuel depending on the chemical structure of these extracts. The final conclusion of this work is that any crude oil with a light Arabic class (has a relative density API less than 38 and a Kw lower than 12.1) is suitable for the production of lubricated oils from the crude oil.

Engine Oils

Engine oils are made from crude oil and its derivatives by mixing of certain other chemicals (additives) for improving their certain properties. Lubricating oil is used to lubricate moving parts of engine, reducing friction, protecting against wear, and removing contaminants from the engine, act as a cleaning agent, and act as an anticorrosion and cooling agent. This research effort focuses on comparative study of re-refined engine oils by extraction of composite solvent, single solvent, and acid treatment methods. Composite solvent was made up of butanol-propane and butanone; propane was used as single solvent. Different properties of refined oil and waste oil were analyzed, such as cloud and pour point, flash point, specific gravity, ash content, viscosity, moisture ratio and acid value. On the basis of experimental work, it was found that the iron contamination decreased from 50 ppm to 13 ppm for composite solvent; for propane solvent it decreased up to 30 ppm and 15 ppm for acid treatment. Results from the flash point, pour point, viscosity, specific gravity, and ash percentage were improved at different degrees, but the best results were seen by using the composite solvent with having drawback of expensiveness.

Corrosion is a severe matter regarding the most of metal using industries such as the crude oil refining. The formation of the oxides, sulfides or hydroxides on the surface of metal due to the chemical reaction between metals and surrounding is the corrosion that  highly depended on the corrosive properties of crude oil as well as the chemical composition of ferrous metals since it was expected to investigate the effect of Murban and Das blend crude oils on the rate of corrosion of seven different ferrous metals which are used in the crude oil refining industry and investigate the change in hardness of metals. The sulfur content, acidity and salt content of each crude oil were determined. A series of similar pieces of seven different types of ferrous metals were immersed in each crude oil separately and their rates of corrosion were determined by using their relative weight loss after 15, 30 and 45 days. The corroded metal surfaces were observed under the microscope. The hardness of each metal piece was tested before the immersion in crude oil and after the corrosion with the aid of Vicker’s hardness tester. The metallic concentrations of each crude oil sample were tested using atomic absorption spectroscopy (AAS). The Das blend crude oil contained higher sulfur content and acidity than Murban crude oil. Carbon steel metal pieces showed the highest corrosion rates whereas the stainless steel metal pieces showed the least corrosion rates in both crude oils since that found significant Fe and Cu concentrations from some of crude oil samples. The mild steel and the Monel showed relatively intermediate corrosion rates compared to the other types of ferrous metal pieces in both crude oils. There was a slight decrease in the initial hardness of all the ferrous metal pieces due to corrosion.

Hazelnuts are one of the most appreciated nuts worldwide due to their unique organoleptic and nutritional characteristics. The present work intended to analyse several physical and chemical properties of different hazelnut varieties grown in Portugal, namely Tonda de Giffoni, Grada de Viseu, Segorbe, Longa de Espanha, Butler, Gunslebert, and Negreta. In general, the results revealed statistically significant differences between the varieties under study. The Gunslebert had more elongated hazelnuts and with heavier shelled fruits, while the kernels of the Grada de Viseu revealed to be heavier. Grada de Viseu was harder in the shell, Gunslebert had a harder core, and Segorbe was more resistant to fracture. Fat was the more representative component for all varieties and in some cases the values of moisture and water activity were over the recommended amount (≥0.62). Tonda de Giffoni was the variety with the highest induction time, indicating the highest oxidation stability. Moreover, discriminant analysis revealed that the variables more important to distinguish the varieties were protein (λ = 0.007) and water activity (λ = 0.010). The results of this study help to better understand the differences between some hazelnut varieties that are cultivated in Portugal, which gives important hints for all players in the hazelnut sector.
