Base Oils

The base of the final product is the base oil. The final product is ready for use and is a mixture of base oil (or several base oils) and additives. Additives improve the properties of the base oil. Base oils can be mineral or synthetic based. Base oils or base stocks are created from separating and cleaning up crude oil. They are one of several liquid components that are created from crude oil. The crude oil refining process will be briefly described. The American Petroleum Institute implemented a system for describing various base oil types. The result was the development and introduction of base oils group numbers. The API numbers of various base oil groups and the main differences between them will be explained. At the end, premium quality hydraulic oil and its main characteristics will be presented.

An increasing interest in acidic fractions in crude oil was prompted by the corrosion problems that these compounds caused during oil refining process. This corrosion is associated with the total acid number (TAN). With the anticipated growth of acidic crudes in the market, a new technology for removal of the acidic fractions was introduced. Petronas Penapisan Melaka Light Crude (B) with TAN values of 2.52 was studied. The ammoniated polyethylene glycol (PEG) was used as the deacidifying agent in this study with a concentration range of 100-2500 mg/L. Data indicated that the optimal content of ammoniated polyethylene glycol in crude B was 1500 mg/L, and PEG with molecular weight of 2000 was the most promising co-solvent with the reagent/oil ratio being 0.4:1 (wt/wt). A reaction time of 5 min with a suitable reaction temperature of 40°C and optimal stirring time of 5 min were sufficient to achieve the goal for crude oil B. The TAN was lowered to 0.28 for crude oil B. The percentage of acid removal for crude B was 78. An increase in the concentration of basic chemical reduced the TAN value for crude oil B to less than 1.

Operation Cost

In this paper, we present a density-method-based model to allocate the refining cost to petroleum products such as gasoline and diesel. By using this model, we also present an empirical study of China, which is based on a virtual crude oil refining process proposed referring to the technical configuration of oil refining industry in China. Three scenarios of the cost of gasoline and diesel are illustrated referring to different settings of the change of the international crude oil prices. The results indicate that the cost of gasoline and diesel change nearly the same amplitude as the change of crude oil price. However, the margin between the cost of gasoline and diesel will slightly increase with the rise of crude oil price. Besides, we also present a sensitivity analysis of the operation cost of each unit in the refining process. The results reveal that the operation cost of catalytic reforming is the most important influencing factor of the cost of gasoline, while the operation cost of hydrogen cracking influences the cost of diesel mostly.

The Impact

The purpose of this study is to analyze the impact of Foreign Direct Investment, Gross Domestic Product, Energy Consumption, Electric Consumption, and Meat Consumption on CO2 emissions of 41 countries in the world using panel data from 1999 to 2013. After analyzing 41 countries in the world data, furthermore 17 countries in Asia was analyzed with the same period. This study utilized quantitative approach with Ordinary Least Square (OLS) regression method. The results of 41 countries in the world data indicates that Foreign Direct Investment, Gross Domestic Product, Energy Consumption, and Meat Consumption significantlyaffect Environmental Qualities which measured by CO2 emissions. Whilst the results of 17 countries in Asia data implies that Foreign Direct Investment, Energy Consumption, and Electric Consumption significantlyaffect Environmental Qualities. However, Gross Domestic Product and Meat Consumption does not affect Environmental Qualities.

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.
