  • Using FTIR spectroscopy to measure hydrocarbon pollution in water

    According to the World Health Organization (WHO) and UNICEF’s 2015 Progress on Sanitation and Drinking Water report almost 700 million people around the world don’t have access to clean drinking water [1]. Poor water quality is beginning to return to the developed world too. The strain of population growth, intensified agricultural practices and continued industrial expansion have are ...

  • 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 ...

  • The Chemical Route to a Carbon Dioxide Neutral World

    Excessive CO2 emissions in the atmosphere from anthropogenic activity can be divided into point sources and diffuse sources. The capture of CO2 from flue gases of large industrial installations and its conversion into fuels and chemicals with fast catalytic processes seems technically possible. Some emerging technologies are already being demonstrated on an industrial scale. Others are still ...

  • 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 ...

  • Effect of optimized three-component antiscalant mixture on calcium carbonate scale deposition

    The mixture of 1-hydroxyethane-1,1-diphosphonic acid (HEDP), and polyacrylic acid (PAA) and synthesized hydrolyzed polymaleic anhydride (HPMA) was optimized by using simplex lattice of Design-Expert software through calcium carbonate precipitation method. The optimum mass ratio of HEDP, PAA and synthesized HPMA was obtained at 10/10/80, which showed excellent performance on controlling calcium ...

  • 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 ...

  • Case study - TPH in produced sand for overboard discharge

    Customer uses TD-500D to measure TPH concentrations in produced sand on an offshore oil platform in Malaysia.  The sand contains high levels of crude oils and must be treated on-site prior to dumping it overboard.  The TD-500D was calibrated to Sitelab's TPH calibration kit, product CAL-056.  Methanol solvent was used to extract the samples.  For comparison, samples were also ...

  • 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 ...

  • How can we reduce concrete’s hefty carbon footprint?

    Bit by bit, innovators are chipping away at this ubiquitous material’s environmental downsides A roomful of materials scientists, gathered at UCLA for a recent conference on “grand challenges in construction materials,” slowly passed a brick-size white block around the room. They held in their hands, briefly, part of the solution to one of those grand ...

  • How can we reduce concrete’s hefty carbon footprint?

    A roomful of materials scientists, gathered at UCLA for a recent conference on “grand challenges in construction materials,” slowly passed a brick-size white block around the room. They held in their hands, briefly, part of the solution to one of those grand challenges. The white block, rock solid and surprisingly lightweight, was a new alternative to cement, the glue that holds ...

  • 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, ...
