  • Latest innovative solutions for PAH & VOCs monitoring in air – Case study presentation

    Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently ...

  • Smart LDAR — more cost-effective?

    On December 19, 2008, EPA issued a final rule establishing a voluntary Alternative Work Practice (AWP) to detect leaks of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from process equipment (FR Vol. 73, Number 246), thereby providing the regulated community additional flexibility in complying with leak detection and repair (LDAR) requirements. The AWP allows owners or ...

  • Sample System Best Practices for Water and Hydrocarbon DP Applications

    Abstract Sampling techniques for BTU and moisture measurements are well understood but applications beyond the routine requires additional attention to detail. Two such applications are the subject of this paper. The first is the measurement of low level moisture (1 – 1,000 ppbv) for cryogenic processes. Measuring moisture below 1 ppm is an entirely different world from the traditional ...

  • Read about Confined Space in Construction and Atmospheric Testing Right Here!

    In 1993, 29 CFR 1910.146 went into effect as the first federal legislation governing entry into permit-required confined spaces in general industry. Because some industries, such as the construction industry, were covered by specific Occupational Safety and Health Administration (OSHA) safety regulations, they were exempt from the confined space entry requirements of the general industry rule. ...

  • AGIP KCO - H2S elimination

    CETCO was approached by AGIP KCO and asked to propose a treatment package capable of Hydrogen Sulphide (H2S) removal from aqueous fluid returns from well flow back and stimulation activities. These activities were planned for new well perforation flow backs and acid stimulations in the Caspian Sea off the coast of Kazakhstan. Here, production wells typically produce gas with extremely high ...

  • Preliminary assessment of trace metals and polycyclic aromatic hydrocarbons in the sediments

    Total concentrations of Cd, Cr, Co, Fe, Pb, Ni, Mn and Zn were determined by atomic absorption spectrophotometry in the surface sediments of Taylor Creek, Southern Nigeria. The most concentrated trace metals, ranging from 113.2 to 5160.7 mg/g-dry weights were Fe, Pb, Mn, Ni and Zn. There was no significant variation in sediment-associated metal levels (P>0.05). The Metal Pollution Index (MPI) was ...

  • PID in industrial hygiene

    Industrial (or occupational) hygiene places the emphasis on prevention of ill health from work, through recognising, evaluating and controlling the risks. For anyone working with hazardous compounds, these chemicals represent a significant potential source of risk. Modern PID instruments provide reliable detection of over 200 of the most dangerous chemicals, helping to ensure effective industrial ...

  • How Accurate is Your Monitor?

    When you consider the many regulations and guidelines that health and safety officers and first responders are faced with, it is amazing they maintain the ability to detect such a wide variety of hazardous pollutants and toxic agents.  There is no lack of regulations governing how to monitor chemical compounds, and the list grows longer all the time.  New standards for portable gas ...

  • Distributed Thermal-Acoustic Data Integration

    Silixa has developed a technique called Distributed Thermal Acoustics (DTA) to monitor simultaneously the thermal and acoustic profile along a hybrid optical fibre cable in submarine environments. Using its world leading distributed fibre optic technology (ULTIMATM DTS and iDASTM) Silixa deployed an optical fibre cable along the seabed and across the water column in an active gas seepage ...

  • The Benefits of Nitrogen and Carbon Dioxide for Food Processing

    The Benefits of Nitrogen and Carbon Dioxide for Food Processing A blend of gases -- carbon dioxide, oxygen, and nitrogen -- help preserve packaged food by reducing the amount of oxygen inside the sealed package. Gas flushing or Modified Atmosphere Packaging, as the process is called, also reduces the amount of processing that food must undergo. This preserves the quality and ...
