  • Water treatment technology for produced water

    Large amounts of produced water are generated during oil and gas production. Produced water, as it is known in the oil industry, is briny fluid trapped in the rock of oil reservoirs. The objective of this study was to test produced waters from a Montana USA oilfield using a mobile station to design a plant to cost efficiently treat the produced water for agricultural irrigation. We used combined ...

  • Measuring Oil and Grease in Produced Water - Case study

    INTRODUCTION When the United States Environmental Protection Agency (USEPA) developed the National Pollutant Discharge Elimination System (NPDES) in the 1970s, oil and grease in produced water was one of the pollutants which was limited. Unlike other parameters, oil and grease is not a unique chemical entity, but is a mixture of chemical species that varies from source to source. It is ...

  • Analysis of sludge aggregates produced during electrocoagulation of model wastewater

    This paper presents the results of the study of sludge aggregates produced during electrocoagulation of model wastewater of a composition corresponding to the effluents from the cellulose and paper industry. Wastewater was electrocoagulated statically using aluminium electrodes with a current density of 31.25 A m−2 and 62.50 A m−2. In subsequent stages of the treatment, sludge flocs were ...

  • Emulsan analysis produced by locally isolated bacteria and acinetobacter calcoaceticus rag-1

    Emulsifiers are widely used in industry, e.g., in medical and cosmetic products and in food systems. They can be used as agents to combat oil spills on beaches and in the sea. The materials that are currently in use commercially as emulsifiers are mainly produced by chemical synthesis. There is a great interest in studying bioemulsiflers because they have some advantages, such as theft ...

  • Optimized data handling for automatically calculating the Hydrocarbon Index (HI) of “Produced Waters” from gas chromatographic analysis with Galaxie™ Software

    The extraction of Oil and Gas from Subsea wells produces large quantities of waste water contaminated with hydrocarbons. These “Produced Waters” are disposed of directly into the oceans. Determination of the Hydrocarbon Index (HI) is required to meet environmental legislation.Traditionally infra red methods have been used but these require solvents extraction using solvents that present their own ...


  • Measurement of Hydrocarbons in Produced Water Using Fiber Optic Sensor Technology (An Alternative to Freon Extraction and IR Analysis Methods)

    Due to the non-availability of Freon, there is need for an alternative method to measure the concentration of hydrocarbons in the effluent from oil water separators in use in the oil industry today. Current methods use solvent extraction and IR analysis of water samples. In this paper we present an alternative method, which does not use any solvents and can provide in-situ analysis of the ...

  • Energy and exergy analysis of a novel multigeneration system producing cooling, heating, power and pure water

    A novel multi–generation system producing power, pure water, cooling and heating is proposed and analysed in detail. The system comprises a hybrid generator-absorber heat exchanger (GAX), the Organic Rankine Cycle (ORC), the absorption heat transformer (AHT) and a desalination system. For comparison purposes, three working fluids, including R123, Isopentane and n–butane are considered in the ORC. ...

  • 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 ...

  • 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 ...

  • Decision making for produced water management: an integrated multi–criteria approach

    Developments of effective produced water (PW) management strategies pose a challenge to the offshore petroleum industry. In this study three PW minimisation systems: down hole oil–water separation (A1), chemical water shut off (A2) and mechanical water shut–off (A3) were evaluated based on fourteen pre–selected criteria from environment, cost and technical point ...

  • Successful Presentation of White Paper at the 24th Annual Produced Water Society Seminar

    President Gary Bartman of Turner Designs Hydrocarbon Instruments  successfully presented his white paper titled "Produced Water Monitoring: Performance Improvements" at the 24th Annual Produced Water Society Seminar 2014. The white paper, "Produced Water Monitoring: Performance Improvements", explained how the continuous on-line monitoring of oil concentration in produced water for discharge ...

  • Two phase partitioning bioreactor applied to produced water treatment

    Produced waters are the largest waste associated with the production of oil and gas; they contain dissolved salts, oil (dissolved and scattered organic compounds), chemicals and additives involved in the oil well operations, suspended particles, sand and other compounds, making their treatment very complex. In this paper, we propose the use of a TPPB (two phase partitioning bioreactor) for the ...

  • A study on the quantities and potential use of produced water in southern Iraq

    This paper presents the results of an analysis of volumes and chemical composition of produced water (PW) accompanying oil production from five of the largest oilfields in the world situated in Basrah, Iraq. PW is potentially a valuable water resource particularly there where the ramp up of oil production puts further strains on water and the environment in an area already having severe water ...

  • Evaluation of Potential Benficial Reuse of San Ardo Produced Water

    ABSTRACTThe goal of this DOE, Aera Energy LLC, and Kennedy/Jenks Consultants funded project was to evaluate the potential for treatment and beneficial reuse of produced water from an oilfield in San Ardo, California. A 10 - 30 gpm reverse osmosis (RO) pilot plant was constructed and operated for nine months. The key constituents of concern include total dissolved solids (7000 mg/l ...

  • Solvent-free oil-in-water analysis

    Non-ionic surfactants can homogenize oily, produced water samples, creating optically clear microemulsions that are ideal for fluorescence measurements [1]. The use of surfactants to reduce fouling and improve the performance of on-line, fluorescence-based, oil-in-water monitors has been reported previously [2,3]. This paper describes the use of surfactants to prepare discrete water samples ...

  • Musty odor producing benthic cyanobacteria in the Tama River (Japan) and identification of species by genetic analysis

    In upstream reaches of the Tama River, musty odor substance (2-methylisoborneol (2-MIB)) began to be detected in 2008 and the concentration has been increasing thereafter. Then, in 2012, 2-MIB in raw water of a water treatment plant reached 210 ng/L. It was suspected that cause of musty odor was benthic cyanobacteria (Phormidium) which attached to stones on the riverbed. However, ...

  • Assessing the impacts of local and imported produce on the public and the environment

    European environmental groups have been calling to switch from imported agricultural produce to locally grown produce, citing positive social and economic impacts as well as environmental ones; and especially the benefit of reducing the environmental pollution and greenhouse gas emissions caused by long-distance food transportation. In Israel, in contrast, there have been calls to increase ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...
