  • 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 ...

  • 99% of Oil from Leaking tanks remediated - Case study

    Spills and leaks from domestic and commercial oil tanks are a very common occurrence, caused either by the refilling of tanks or as the result of leaks. Very  often old metal tanks corrode and start leaking oil onto the ground around the tank. Also the tanks themselves become covered in dried hydrocarbons and become significantly discoloured, even black. Spilled oil can seep into the ground, ...

  • LNAPL At Petroleum Product Terminal - Case Study

    ABSTRACT BOS 200® was injected at a refined petroleum product terminal to remediate LNAPL in groundwater. Within one year after treatment, the site received a No Further Action status. CHALLENGES The remedial goal was to eliminate the reoccurrence of light non-aqueous phase liquid (LNAPL) which persisted with no apparent pattern. Annual ...

  • 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 ...

  • 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 ...

  • PAHs in Parking Lot Sealcoats - Case Study

    There is growing concern - and regulations in the works - over the use of sealcoating products due to their high PAH content.  In the United States and elsewhere, most sealcoats are made from coal tar which can be toxic to aquatic life and threaten public water supplies from rain and runoff.  Sample was collected from a freshly treated parking lot in Seabrook, New Hampshire. The ...

  • Assessment of organic micropollutants occurrence in treated wastewater using heat shock protein 47 stress responses in Chinese hamster ovary cells and GC/MS-based non-target screening

    Combining bioassays and analytical chemistry screening is a powerful approach to assess organic micropollutants which are the main contributors to toxic potential in complex mixtures of treated wastewater (TWW). The aim of this study was to perform a comprehensive toxicity assessment of treated effluents using stress response bioassays and then to assess the occurrence of the organic ...

  • Fast analysis of semi-volatile organic compounds using PTV-GC–TOF MS

    The evaluation of semi-volatile organic compounds (SVOCs) in environmental matrices poses many challenges for the analyst, not least the vast number that may be encountered in any given analysis. In addition, analyte reactivity and the potential for multiple analytes to co-elute makes achieving the required method detection limits (LODs or MDLs) quickly and cost-effectively a formidable task ...

  • Synthesis of granular nanozeolite NaA from Phragmites australis for removal of total petroleum hydrocarbon

    The purpose of this study was to synthesize granulated nanozeolite NaA particles from Phragmites australis in order to evaluate their efficacy for removal of total petroleum hydrocarbon (TPH). The perennial wetlands grass P. australis was chosen for study because it is one of the most abundant plants found growing around oil refineries. Fourier transform infrared ...

  • Chronic toxicity of selected polycyclic aromatic hydrocarbons to algae and crustaceans using passive dosing

    Due to the large number of possible aromatic hydrocarbon structures, predictive toxicity models are needed to support substance hazard and risk assessments. Calibration and evaluation of such models requires toxicity data with well‐defined exposures. The present study has applied a passive dosing (PD) method to generate reliable chronic effects data for eight polycyclic aromatic hydrocarbons ...

  • 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, ...

  • Case study - EDRO in soil at wharf remediation site

    Sitelab Calibration Kit CAL-042 is used for EDRO analysis. The UVF-3100 detects hydrocarbons in the C10-C36 range. A Licensed Site Professional (LSP) used Sitelab to investigate a commercial waterfront property, contaminated with a plume of LNAPL resulting from fuel tanks which once stored heating oil, diesel and gasoline dating back to the 1950s. The site is in Massachusetts, where laboratories ...
