  • Validation of Salt Water Disposal Well Treatment Plants with Handheld Oil in Water Sample Analyzer

    Salt Water Disposal (SWD) well operators often dispose a substantial volume of oil inadvertently when injecting salt water, thereby losing the opportunity to sell the oil on the market and potentially reducing the ability to inject water in the well. Injection facilities are typically operated with minimal instrumentation or system optimization, which means the operators don't know how much, or ...

  • Reservoir Management - Online Oil-In-Water Monitor - Case Study

    Background Older generation online oil-in-water (OiW) monitors may suffer from fouling of optics due to scales, soaps, emulsions, sludge, etc., resulting in inaccurate (usually low) concentrations. New generation OiW monitors: Yield more accurate O  iW concentrations Improve accuracy of the OiW measurements, allowing operators to optimize water ...

  • Oil in Water and FAME ASTM Standards | Spectroscopy Guides

    In this article we will briefly look into various analysis standards, namely those of the American Society for Testing and Materials (ASTM) but also some others such as IP and EPA. Throughout, we'll be mentioning the place our FTIR analytical equipment has in certain application areas.  Standards for Oil in Water Detection ...

  • Separation of emulsified crude oil in saline water by flotation with micro- and nanobubbles generated by a multiphase pump

    The flocculation–column flotation with hydraulic loading (HL, >10 m h−1) was studied for the treatment of oil-in-water emulsions containing 70–400 mg L−1 (turbidity = 70–226 NTU) of oil and salinity (30 and 100 g L−1). A polyacrylamide (Dismulgan, 20 mg L−1) flocculated the oil droplets, using two floc generator reactors, with rapid and slow mixing stages (head ...

  • Monitoring once through cooling water - Case study

    The Situation Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil.  These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often ...

  • Techniques for Oil in Water Analysis

    The people responsible for conducting oil in water measurements understand that the measurement can be quite challenging. Wastewater from different sources can contain many different types of hydrocarbons, each with different chemical make-ups. On top of the lack of chemical uniformity in different oils, there has been a ...

  • 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 ...

  • Monitoring Oil in Cooling Water - Case Study

    The Situation A municipal power plant in the southern United States operates more than 10 stationary power plant engines capable of producing 52 megawatts of electric power. The plant is part of a larger statewide power grid system. Within the grid, the municipality brokers the purchase or sale of power hourly, based on the needs of municipality and the market rate for power on the grid ...

  • Monitoring fuels in Stormwater - Case study

    The Situation A major pipeline company has large storage tank farms throughout the Western States. The pipeline company transports, stores, blends additives, and distributes gasoline, diesel, and jet fuel to retail service stations and airports. Due to the quantity and movement of fuel at these facilities, there is always the potential for fuel spills. These facilities prevent out of ...

  • Emulsion breakingtechniques for oil in water solvent extractions

    Certain types of samples, such as those containing detergent, may form emulsions when doing an oil in water extraction into a solvent. The boundary between the solvent and the sample will have an emulsion layer that lias a cloudy or milky appearance as shown in tlris photo. According to U.S. EPA Method 1664, "if the emulsion is greater than one-third the volume of the solvent layer. Hie ...

  • Different technology options for monitoring oil in produced water – inline continuous monitoring and IR analysis

    No offshore facility wants to be caught with a sheen around their platform as that can result in a costly fine for exceeding discharge permit limits for oil. Onboard oil in water analyzers are necessary to ensure the oil/water separation systems are functioning properly before overboard disposal of the produced water. Bench top analyzers have traditionally been used to test oil in water although ...

  • A Guide to Oil in Water Monitoring for Environmental Compliance

    Applications for industrial oil in water monitoring can vary greatly. In upstream and midstream oil and gas production applications, monitoring separation efficiencies is key to optimize production rates, preventative maintenance, chemical use, flow, and environmental compliance. Separated water from the oil is called produced water and it must be cleaned of oil before disposal or ...

  • Portable IR Analyzers Provide Petroleum & Wastewater Industries with Accurate Oil Content Measurements

    Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on off-shore and on-shore drilling platforms for well over 45 years. U.S. EPA methods 418.1 and 413.2 were used extensively on a worldwide basis until the Montreal Protocol called for Freon (the solvent used in the analysis) to be phased out. Infrared analysis using tetrachloroethylene (perchloroethylene) is ...

  • Enhanced oil–mineral aggregation with modified bentonite

    The application of modified-bentonite-enhanced oil dispersion in water and oil–mineral aggregate (OMA) formation was studied in the laboratory. The effect of modification on the surface properties of bentonite was characterized. The hydrophobicity and surface electric properties of bentonite were significantly improved by attaching cetyltrimethyl ammonium bromide to its surface. The ...

  • Matching Oil in Water Analyses with Regulatory Methods - Case study

    When analyzing oil and grease in water while out in the field, it is important to use an EPA approved method and equipment. While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, ...

  • Matching oil in water analyses with regulatory methods

    While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, the "oil" is anything that is extracted into hexane and remains after the hcxanc has been evaporated and appears as weight. In regions ...
