  • Applications of a Portable Gas Spectrometer

    In the realm of natural gas processing, enterprises don’t always find it economical to send products back to the lab and wait for test results. Being able to perform on-the-spot, highly accurate compositional analysis with gas chromatography equipment can reduce operational costs and help companies determine on-the-spot accurate gas levels in a natural gas stream. ...

  • Confirming Natural Attenuation Processes at a Coastal Site - Case Study

    Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...

  • A solution to fracturing water supply and disposal issues

    “Water, water, everywhere, Nor any drop to drink.” –The Rime of the Ancient Mariner, Samuel Taylor Coleridge Many topics of conversation among oil and gas industry professionals are predictable – oil price trends, the “great shift change” imperiling the available workforce, and production quotas and caps from OPEC. Yet one pressing topic among those developing ...

  • PetroSense hydrocarbon sensors and their applications

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

  • 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 ...

  • Ethylene Plant Treatment Hydrocarbon Engineering

    Ethylene is the most commonly produced petrochemical product. The bulk of annual commercial ethylene production is based on thermal cracking of hydrocarbon feedstocks with steam. Usual raw materials for pyrolysis are refinery gas, liquid petroleum gas (LPG), natural gas liquids (NGL), naphtha or gas oil. The production of ethylene is a very complex process, including cracking, cooling, ...

  • Fate of hydrocarbon pollutants in source and non-source control sustainable drainage systems

    Sustainable drainage (SuDs) is an established method for managing runoff from developments, and source control is part of accepted design philosophy. However, there are limited studies into the contribution source control makes to pollutant removal, especially for roads. This study examines organic pollutants, total petroleum hydrocarbons (TPH) and polycyclic aromatic hydrocarbons (PAHs), in ...

  • Methane conversion to higher hydrocarbons over copper loaded BZSM-5 in the presence of oxygen

    The direct conversion of methane to higher hydrocarbons either over metal catalyst or zeolite has not been successful so far in achieving the methane conversion with higher hydrocarbons selectivity within the economic range due to oxidation of the product. The present research aims at improving the performance of BZSM-5 catalyst with the addition of copper. Catalytic behaviours at different ...

  • In Situ electromagnetic heating for hydrocarbon recovery and environmental remediation

    Introduction Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. These effects assist in sweeping the substances ...

  • Monitoring hydrocarbons in Bilge water - Case study

    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 other contaminants may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged ...

  • Slug of Hydrocarbon contaminating amine case study

    A Gulf Coast refinery’s amine system was contaminated with up to 3% hydrocarbon. The contamination consisted of hydrocarbon from upstream process units and particulate. The hydrocarbon consisted of LCO and heavy diesel. The current system consisted of an undersized flash tank and a 20% slipstream filtration. The current system could not remove the contaminants so the refinery had to ...

  • Using a Self Bailer on Containment Sumps to Filter Hydrocarbons

    How do you eliminate problems associated with the collection of rainwater in outdoor containment systems and maintain compliance with EPA and Clean Water Act regulations?  Since most outdoor oil storage tank sumps and oil drum spill pallets will inevitably be exposed to local precipitation and storm water runoff from nearby catchment surfaces, it is necessary to make sure you ...

  • Hydrocarbon reserves exploration by real–time expert seismology and non–linear singular integral equations

    By using a non–linear 3–D elastic waves real–time expert system, the new theory of 'real–time expert seismology' is proposed, for the exploration of the on–shore and off–shore oil and gas reserves all over the world. This highly innovative and groundbreaking technology is working under real time logic for searching the on–shore and off–shore petroleum reserves developed on the continental crust ...

  • Hydrocarbon Processing: Non-phosphorus corrosion inhibitor optimizes cooling tower uptime for environmental compliance

    Cooling water systems play a critical role in the efficient operation of hydrocarbon processing facilities. Ensuring that these systems efficiently cool and condense the various process streams is essential to minimizing operating costs and maximizing plant performance and profitability. Common challenges to maintaining these systems at peak performance come in the form of corrosion, pitting and ...

  • Phytoremediation of Alkylated Polycyclic Aromatic Hydrocarbons in a Crude Oil-Contaminated Soil

    Abstract  Phytoremediation uses plants and their associated microorganisms in conjunction with agronomic techniques to remove or degrade environmental contaminants. The objective of the field study was to evaluate the effect of vegetation establishment plus fertilizer addition on the biodegradation of alkylated polycyclic aromatic hydrocarbons in a crude oil-contaminated soil. Four ...


  • 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 ...

  • Analytical Solutions for Free-Hydrocarbon Recovery using Skimmer and Dual-Pump Wells

    Accidental release of petroleum hydrocarbons to the subsurface may occur through spills around refineries, leaking pipelines, storage tanks or other sources. If the spill is large, the hydrocarbon liquids may eventually reach a water table and spread laterally in a pancake-like lens. Hydrocarbons that exist as a separate phase are termed light non-aqueous phase liquids (LNAPL). The portion of the ...
