  • Field verification of on-line hydrocarbon dew point measurements

    Introduction The Michell Condumax II applies a fundamental measurement principle for direct measurement of hydrocarbon dew point. Measurement performance is assured through comprehensive factory test and calibration, to verify that each analyzer offers accurate determination of the temperature at which hydrocarbon condensate forms. Further extensive examination confirms highly sensitive ...


  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • HDPE - A Hydrocarbon Resistant Membrane?

    Most brownfield redevelopment and environmental protection applications require the use of a hydrocarbon resistant membrane.  However, each membrane material will vary in its ability to resist chemical attack and its effectiveness as a barrier to permeation.  It is essential that a barrier material prevents the migration of contaminants, thereby not harming the surrounding environment ...

  • Monitoring Hydrocarbons in Bilge Water

    The Situation Various processes onboard ships, such as machinery wash-down, maintenance, and leakage generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as garbage may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited ...

  • PetroSense Hydrocarbon Sensors and Their Applications

    The increasing concern about hydrocarbon contamination of process water andproduced water has created an increasing need for in-situ, real time, and accurate low costinstrumentation that can provide rapid detection and easily usable in the field. PetroSense sensors [1,2] represents “best in breed” technology for the detectionof total petroleum hydrocarbons (TPH). PetroSense sensors ...

  • Infrared differential absorption Lidar (DIAL) measurements of hydrocarbon emissions

    We report the application of an infrared (IR) differential absorption Lidar (DIAL) system (also capable of ultra violet measurements) built at the National Physical Laboratory (NPL), UK, to field measurements of total site emissions (controlled and fugitive) from petrochemical and landfill installations. The validation of the IR-DIAL was carried out via a series of controlled field experiments ...

  • Measurement of hydrocarbons in produced water using fiber optic sensor technology

    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 ...

  • Analytical Devices for the Measurement of Water Vapor and Hydrocarbon Dew-Point in Natural Gas

    Introduction The determination of water vapor (water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to corrosion of plant and equipment. Furthermore, water vapor present in natural gas streams affects the ...

  • Understanding and Monitoring Hydrocarbons in Water

    Untitled Document 1. Introduction Oil contamination continues to be a very hot topic, due largely in part to recent catastrophic events with shipping ...

  • Testing Tar & Asphalt for Polyaromatic Hydrocarbons

    New regulations by the European Union require laboratory testing for polyaromatic hydrocarbons (PAHs) when recycling or disposing old tar or asphalt from road planings. Sitelab’s portable UVF-3100D and TD-500D analyzers have similar sensitivity to these types of compounds. The equipment is easy to operate and samples can be tested in the field in less than ...

  • Heavy metal & hydrocarbon contaminated sludge

    Solidification of Heavy Metal & Hydrocarbon Contaminated Sewage Sludge Client: North Lanarkshire Council Project Managers: Jacobs Challenge: The former sewage treatment works were decommissioned in the 1970’s. It is thought that during the closure process, demolition material originating from the ...

  • Hydrocarbon in Water Monitors using Fluorescence

    Hydrocarbon in Water Monitors using Fluorescence are capable of detecting hydrocarbons as low as 5 Parts per Billion and as high as 10,000 Parts per Million depending on the application.  Because only the target hydrocarbons will fluoresce, these monitors have no significant affect due to water turbidity (rust, dirt, gas bubbles, soot, etc.).  Fluorescence monitors provide a measurement ...

  • Modelling of wet deposition of atmospheric polycyclic aromatic hydrocarbons by the consecutive measurements in an urban area, Japan

    The wet deposition for particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs) was modelled from the consecutive measurements of atmospheric concentration and wet deposition for particulate matter and PAHs in Higashi-Hiroshima city, Japan. In order to estimate the model in detail, the wet deposition was classified with that from gaseous and PM phase. The gaseous PAHs assumed to be ...

  • Advances in Optical Techniques for Moisture and Hydrocarbon Detection

    Abstract Every year, the world uses in the region of 100 trillion scf (standard cubic feet) of natural gas (1). All of this gas requires treatment before it enters the pipeline, making natural gas processing a key global industry. Minimization of costs is achieved through optimization of these processes, requiring accurate online measurement of gas composition at multiple points in the ...


  • Particulate polycyclic aromatic hydrocarbons in urban air of Tehran

    Epidemiological studies have shown correlations between the concentration of particles in the air and increase of daily rates of respiratory and cardiovascular diseases and mortality (Douglas et al.,1992; Jonathan et al.,1995; Auron et al.,1995). Elevated lung cancer rates among women in rural china have been attributed to emissions from their coal-fired stoves (Mumford et al.,1987;Alder and ...
