These include tank condensation, leakage of steam from heating coils, and bunker tank leakage. 8 (Sattarin et al. The accuracy of the experimental density data was determined using Standing and Katz method. Another statistical test was performed on the data and the models; a measure of the standard deviation (SD) was performed between the experimental and calculated data with Eq. Correlations for crude oil density and temperature are found by use of tools based on ASTM D 1250-04 and IP 200/04 (API Manual of Petroleum Measurement Standards, Chapter 11- physical properties Data, Section 1:Temperature and pressure volume correction factors for generalised crude oils, refined products and lubricating oils). You have 1000 m3 of a fuel oil with a density of 960 kg/m3 at 15C. Heavy Fuel Oil (HFO) or Black Oil is one of the least expensive of the refined oil fuels and generally can only be used by facilities that have preheating capabilities. Some of these models are discussed in this paper, such as the Beggs and Robinson (1975) model for temperatures ranging from 21 to 146C and the Elsharkawy and Alikhan (1999) model based on crude oil samples from the Middle East for temperatures ranging from 38 to 150C. The results were acceptable and well fit by an equation of the following form: where Naseri et al. The Heavy Fuel Oils (HFOs) category includes two finished products (residual fuels) and the primary refinery streams from which they are blended. The volume of your fuel oil at 100C is 1000m3*1.065 = 1065 m3. Heavy Fuel Oil (HFO) is the residual product that remains after refining the crude oil. c, and is the acentric factor. Other authors suggest that the variation in compositions is why correlating the viscosity of heavy crude with high accuracy is improbable (Beal 1946). The principal objective of this paper is to obtain exact models that can successfully predict these two important fluid properties covering a wide range of temperatures.

Viscosity and density play very important roles in oil production, transportation through pipelines, and oil recovery processes. 4. HFO is used as a marine engine fuel because of its cheapness, but it does contain a lot of impurities and must be kept at a high temperature both during storage and use in ships main engines. The values of critical parameters (P In addition, Kartoatmodjo and Schmidt (1994) developed an empirical correlation to predict the viscosity of dead oil with 3588 data points from 661 dead oil samples that covered gravities ranging from 14.4 to 58.9API, viscosities ranging from 0.5 to 682cP, and temperatures ranging from 75 to 320F. Some results showed good agreement with the data, whereas other models had poor predictive capabilities. Please read AddThis Privacy for more information. 2. However, this new model is easy to use, provides fair accuracy and precision over a wide range of heavy oil gravities, and could be used to predict better outcomes in future works. 1964). p 5. Another application of the EoS was made but this time using the Pederson corresponding state with the PengRobension EoS this trail also gave us a very high absolute error with the value of 126%. At a lower temperature the fuel will gel, thereby preventing flow. In Data from the 1995 US Heavy Oil Database. It allows obtaining the viscosity from the measure of the density. Density of oil at given temperature and pressure is expressed via density of oil at 15 deg C and zero overpressure, - temperature correction coefficient, calculated according to the formula, - overpressure correction coefficient, calculated according to the formula, The density of oil at 20 deg C and zero overpressure is calculated according to the formula, The coefficient of volumetric expansion at 15 deg C is calculated according to the formula, Coefficient of volumetric expansion at given temperature is calculated according to the formula, Compression coefficient is calculated according to the formula, If an areometer is used, its readings are corrected using the temperature correction coefficient for areometer glass.

Therefore, developing a comprehensive model of viscosity to include different regions of the world seems to be a very challenging task. Obtaining reliable viscosity and density measurements can be difficult, especially for live oil. Several correlations for predicting dead oil viscosity are available in the literature. https://doi.org/10.1007/s13202-015-0184-8, DOI: https://doi.org/10.1007/s13202-015-0184-8. The ASTM indicates that dead oil viscosity is labeled according to its standard API at 15.5C. Distillate Bunker Oils (ISO 8217) Distillate Fuel Kin. We don't collect information from our users. The recommended properties of HFO [28] include: maximum kinematic viscosity @ 288 K of 5 Pas . After calculating the compressibility factor (Z), the molar volume was calculated, and this value was then converted to density using the molecular weight. J Petrol Explor Prod Technol 6, 253263 (2016). The negative correlation coefficient between the dynamic viscosity and temperature shows that whenever the temperature is increased, the viscosity decreases, indicating an inverse correlation between them. Volume correction factors can be used to calculate the volume of a product at base temperature (15C/59F) if you know the density and volume at another temperature. These applications will - due to browser restrictions - send data between your browser and our server. The results were satisfactory with an R As a result, marine transportation has been referred to as an incineration service for a waste product. Most of the published models for predicting the dynamic viscosity dead oils are unreliable in a wide temperature range. The lowest R Presently, I know the viscosity of a Heavy Fuel Oil which is 1200 cSt at 50 deg C. . Density is the relationship between mass and volume at a stated temperature, and the SI unit is Kg/m3. 8. Deviation of experimental viscosity data from predictive values using EOS. No. The maximum limit of ash content in the fuel is 0.2% m/m. The calibration was done at the temperatures of interest by using ultrapure water. (Easy check: Lowest volume at the lowest temperature). The positive value of the correlation factor between the density and the viscosity indicates a direct correlation, and the equation for these variables follows the form of Eq. The residual fuels are primarily used inindustrial boilers and other direct source heating applications (e.g., blast furnaces) and as aprincipal fuel in marine diesel applications.

The full regulations for packaging, transport and storage are specified in STN 65 7991 as well as in follow-up standards and regulations. How will the volume change if you heat it to 100C? As per the test procedures, triplicate measurements were performed, and the average was used. "State system for ensuring the uniformity of measurements for the density of oil. The original values of the parameters and gave an average error of density more than 90%, but after tuning the parameters and using new values of 0.009, 0.0058, respectively, the average error was 80.3%. How will the volume change if you heat it to 100C? 6 fuel oil; NSFO (Navy special fuel oil) . Thus, the viscosity is directly proportional to density and inversely proportional to temperature, with high correlation between the data. 908. 3 7 4 6 4+ 1. The values were evaluated and tested using different techniques, such as curve fitting, nonlinear regression, and the square method. 6: This oil is called . Each colored line represents a crude oil with a given density at a given temperature. Hydrocarbon Process 55:153158, Labedi R (1992) Improved correlations for predicting the viscosity of light crudes. In this study, heavy oil density was predicted from API and temperature, and then the predicted values of the densities were used in the second step to develop the viscosity correlation. It is very viscous and requires to be kept at a temperature above pour point in bunkers and storage tanks to ensure efficient transfer and combustion. The ash content is related to the amount of inorganic material in the fuel. The . 0.1% - 0.2 % by volume is typical. These approaches were (A) squaring the Pearson product moment correlation coefficient, (B) relative error, (C) standard deviation, and (D) cross plots. To check the ability of the proposed viscosity model to present all experimental data, cross plots of the measured and predicted viscosity values were used. The densities were measured at temperature intervals between 20 and 160C using an oscillating U-tube densitometer; the oscillation period in the vibrating U tube of the densitometer was converted to density using Eq. The maximum limit of carbon residue content in fuel is 22 %. At 200C the correction factor is 0.859. where P is the pressure, T is the temperature, v is the molar volume, R The volume of your crude oil at 15C is 100liters*0.965 = 97 liters. Or, if you know the base volume and density, you can use the volume correction factor to calculate the volume at another temperature. Statistical analyses were conducted randomly for 376 data points of the 30 dead crude oil samples. The accuracy of . Gas oil is a low-viscosity - often clear, yellowish to brownish - liquid with a specific density in the order of 0.85 to 0.89 g/cm 3. [GE03/08]. Only emails and answers are saved in our archive. This graphical presentation also shows that the Standing model describes the data with some minor scattering points around the (y=x) line while the proposed model is giving the best prediction without any scattering between the experimental data and the models measured value. Cetane number is the equivalent reference for light fuel oil such as diesel oil. g is the universal gas constant. In most cases, this parameter has no physical meaning. The kinematic viscosity is about 5 to 7 cSt at 40 0 C. Two other models by Hosain et al. Fuel 78:891903, Glaso O (1980) Generalized pressurevolumetemperature correlation for crude oil system. Cambridge University Press, Cambridge, Elsharkawy AM, Alikhan AA (1999) Model for predicting the viscosity of Middle East crude oils. Normally the level of water in the fuel is very low, since an effort is made by the supplier to deliver the fuel as dry as possible. This value is the first parameter for any model, and the second parameter is the value of the measured temperature. 2 for each case. Density and viscosity have a deep impact on the combustion of existing diesel engines. The CV of a fuel is the heat energy given out during combustion.

Any higher density than this will inhibit HFO water removal treatment through centrifuging. 3. 5: It is a mixture of 75% to 80% of No. Vegetables oils density and viscosity are reduced to match diesel fuel values by heating. Not all HFO is chemically uniform as its components are present in varying percentages depending on the crude oil from which the residuals have been derived as well as the nature of any other products (including diesel) added in order to improve pumping/flow, handling and combustion,or reduce the sulphur content of the fuel (a technique known as blending). This gives value of 800- 1010 kg/m3 for marine heavy fuel oil. The overall result shows that it is not an easy task to generalize a dead oil viscosity model along with the API and temperature. This makes it much cheaper than other lighter marine fuels and is the main reason it is used in marine engines. These applications will - due to browser restrictions - send data between your browser and our server. Density can vary of course, and for heavy fuel oils this varies from 975 to 981 kg/m3 for 10cst oils (density at 15degC and viscosity at 100degC) to between 991 and 1010 kg/m3 for 55cst fuels.
