Abstract

  In this study, several samples of crude oil containing nanoparticles have been studied. However, light crude oil has been evaluated more than other samples. Also, the density of three samples of light, medium and heavy crude oil has been measured in the laboratory. Nano ferric oxide with a range of 75 - 89 nm in diameter is added in crude oil and changes in viscosity, recovery value percentage, precipitation of heavy hydrocarbons, molecular weight are surveyed with various temperature and pressure. Also, the data obtained in these experiments show that with increasing operating temperature, the percentage of deposition of heavy hydrocarbons in oil decreases. The results show the relationship between oils with different molecular weights and the percentage of precipitation of heavy hydrocarbons. Experiments in this section show that the higher the molecular mass of the oil, the higher the percentage of heavy hydrocarbons separated from the oil. The reason for this is that the higher the molecular mass of the oil, the more carbon-containing hydrocarbons there are. The longer carbon chain means a higher percentage of the heavy compounds in the oil, so it can be expected that the higher the molecular mass of the oil, the higher the percentage of heavy matter in it. In addition, the results of this chart also show that as the operating temperature of the oil passing through the sand bed decreases, the amount of heavy hydrocarbon deposits in the oil also increases. The reason for this is that as the operating temperature decreases, the amount of thermal flux and, of course, the amount of heat distribution in the oil decreases, and eventually the percentage of heavy hydrocarbon deposition from oil will also increase.
