  • The crude oil distillation unit

    The crude oil distillation unit (CDU) is the first processing unit in virtually all petroleum refineries. The CDU distills the incoming crude oil into various fractions of different boiling ranges, each of which are then processed further in the other refinery processing units. The CDU is often referred to as the atmospheric distillation unitbecause it operates at slightly above atmospheric ...

  • Quantifying the concentration of crude oil microdroplets in oil–water preparations

    Dissolved constituents of crude oil, particularly polycyclic aromatic hydrocarbons (PAHs), can contribute substantially to the toxicity of aquatic organisms. Measured aqueous concentrations of high–molecular weight PAHs (e.g., chrysenes, benzo[a]pyrene) as well as long‐chain aliphatic hydrocarbons can exceed the theoretical solubility of these sparingly soluble compounds. This is attributed to ...

  • Measuring level of crude oil case study

    MonoScan provides an economical ultrasonic solution for measuring level of crude oil in one of Kaliningrad's well known oil fields. The Eastern Gorino oil field located in Gorino, Kaliningrad near the border of Lithuania, contains 11 oil wells and is capable of producing 200 tons of crude oil per day. The Kaliningrad Geological Oil & Gas company, which owns the field, sought a solution for ...

  • Case study - Canada crude oil sites

    The Canadian Council of Ministers of the Environment requires laboratories to use the CCME’s Petroleum Hydrocarbon (PHC) Method, where GC-FID instrumentation is used to report VPH and EPH hydrocarbon fractions. Sitelab’s popular Extended Diesel Range Organics (EDRO) test typically detects hydrocarbons in the C10 to C36 carbon range, but the UVF will pick up heavier compounds up to ...

  • Crude oil tank profiling case study

    A little while ago we were approached by Cyprus Petroleum Refining Ltd, the largest Cypriot refining company to undertake the sludge profiling of eight crude oil tanks. The company sent two of its most experienced team members to carry out the work. Over a two week period in the middle of summer the team landed the floating roofs of the eight tanks and commenced the sludge profiling using a tried ...

  • Case study - Nigeria crude oil in soil site

    Safic Technologies, Ltd. - Port Harcourt A pilot study was conducted testing soil samples collected from a pipeline spill. Split samples were sent to Sitelab for EDRO analysis and results were the same. Samples were also sent to a Nigerian lab and a highly reputable lab in the United States for confirmation. After testing the samples a second time, the American lab got better results. ...

  • The world needs storage space for crude-oil glut

    Today we are surprising with this new published in the Wall Street Journal. The crude oil storage space in U.S., Europe, South Korea, Southafrica and Japan would be expected to hit the maximum capacity due to a crude-oil production glut. For this ...

  • Isolation and characterization of crude oil degrading bacillus spp.

    Crude oil continues to be used as the principal source of energy and play an important role in the global environmental pollutant considerations. On the other hand, oil will remain as a major source of energy in the next several decades, because a reliable alternative energy comsumption has not yet been substituted. (Trindade et al., 2005, Al- Saleh and Obuekwe, 2005). There are so many bacterial ...

  • Surface Decontamination of Crude Oil by DeconGel 1101 and 1102

    ABSTRACT Surface decontamination efficacy determination of DeconGelTM 1101 and 1102 on aluminum, stainless steel, and concrete surfaces contaminated with Crude Oil (polyaromatic hydrocarbons fraction) was performed with LC/MS (Liquid Chromatography/Mass Spectrometry) according to Environmental Protection Agency (EPA) SW-846 Methods: 3500C (sampling), 8321B (analysis), and 1654A (Analysis of ...

  • Case study - Texas crude oil in soil sites

    Sunset Well Service, Inc. is an environmental contractor located in the Midland/Odessa area of Texas. They use their UVF-3100D analyzer to help excavate and remediate soils contaminated by produced water and crude oil. Laboratories in Texas test TPH using the TX 1005 GC-FID Method. This method is similar to U.S. EPA Method 8015M, but reports the GRO, DRO and ORO fractions separately. Soils from ...

  • Case study - Oklahoma crude oil forensic analysis

    An oil company used Sitelab’s laboratory to perform oil forensic analysis testing crude oils from different well sites to determine the percentage of oil content from two formations. The wells tap into these zones at different depths, thousands of feet below the ground. Knowing what type of oil being pumped is important. All six oil samples had similar GRO content, but the PAH content in ...

  • GC Analysis of Crude Oil Samples in Compliance with ASTM D5307

    In the ASTM D5307 test method, crude oil containing components with boiling points to temperatures in excess of 538C (C44 or equivalent) are analyzed by a simulated distillation GC system by the internal standard method. A detailed boiling point distribution graph is created for the fraction with boiling points lower than 538C. The fraction with boiling points above 538C is calculated as ...

  • Techno-economic assessment of heavy crude oil desalting plant

    Electrostatic desalting is the industrial standard method for removing salt from crude oil. In this study a techno-economic analysis of a crude oil desalting plant is presented. A complete process simulation was conducted using Aspen HYSYS in parallel with a simulation in Microsoft Excel in order to account for salt concentrations. An economic assessment of the proposed design was performed to ...

  • Oil droplet ingestion and oil fouling in the copepod Calanus finmarchicus exposed to mechanically and chemically dispersed crude oil

    The rate of ingestion of oil micro droplets and oil fouling were investigated in the zooplankton filter‐feeder Calanus finmarchicus (Gunnerus, 1770) at three concentrations of oil dispersions ranging from 0.25 to 5.6 mg x L−1. In order to compare responses to mechanically and chemically dispersed oil, the copepods were exposed to comparable dispersions of micron‐sized oil droplets made with ...

  • Kinetics of transesterification crude soybean oil to biodiesel catalysed by magnesium methoxide

    The apparent activation energy of transesterification of soybean oil with methanol was investigated by the use of magnesium methoxide as solid base catalyst. The effect of variations in reaction time and temperature (50-65°C) on the macro reaction rate were studied while the molar ratio of methanol to oil (9 : 1) and the mass ration of catalyst to oil (8 wt%) were held. The experimental data were ...

  • Analysis of the co-movement between Chinese and international crude oil price

    Crude oil price has an important effect on national economic production and safety-stock. In this paper, we analysed the trends of Chinese and international crude oil prices and their fluctuations by testing the Granger causality and the dynamic effects to its counterpart. Results show that from 1997, the trends of Chinese and international crude oil prices are almost identical. The fluctuation ...
