  • Siting and Safe Operation of Liquefied Natural Gas Facilities

    Regulations require facilities to use computer simulations to model potential fire and explosion hazards from accidental liquefied natural gas (LNG) releases. This has required the run of several separate computer models and manual transfer of data among the models, which is a time-consuming process prone to errors. The Code of Federal Regulations (49 CFR 193) defines safety standards for LNG ...

  • Problems of catalytic boiler safety and their role in designing and operation of gas-fired boiler

    In the following paper, some problems of safety for catalytic boilers with fixed and fluidised beds are discussed. The reason is to protect the boiler from gas and fuel-air mixture explosion. For it the conditions excluding the transition from catalytic combustion to flame must be observed, and they are presented in the article for different combustible gases. A special attention has been paid to ...

  • Groundwater Remediation System Cleans Up Oil Spill

    A customer in TX was recently in some hot water with the local municipal water department. Due to excessive rains near the coast of Texas, the water levels have been higher than usual. The company fills storage tanks with diesel at its facility. However one day the tanks were overfilled and instead of going into the ground, they diesel dispersed out via the high rain water and into the local ...

  • Common Treatment Technologies for Nonhalogenated SVOCs in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate nonhalogenated semivolatile organics in water. Treatability studies may be required to determine the contaminant biodegradability for any biodegradation technologies. Treatability studies are also necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic ...

  • Addressing contaminated groundwater with organic mulch permeable reactive barriers

    Organic mulch consists of insoluble carbon biopolymers that are enzymatically hydrolyzed during decomposition to release aqueous total organic carbon (TOC). The released TOC is utilized by microorganisms as an electron donor to transform electrophilic contaminants via reductive pathways. Over the last decade, organic mulch permeable reactive barriers (PRBs), or biowalls, have received increased ...


  • Monitoring in the near future

    Take a look into the lab to see how commercialization of advanced environmental sensory capability is about to happen. Being asked to describe technology breakthroughs in environmental sensors with applications like air and water monitoring prompts the obvious question, 'If the first micro-machined gas chromatograph was demonstrated in 1979, why didn't the environmental sensor market experience ...

  • Methane emissions and airflow patterns along longwall faces and through bleeder ventilation systems

    The National Institute for Occupational Safety and Health (NIOSH) conducted an investigation of longwall face and bleeder ventilation systems using tracer gas experiments and computer network ventilation. The condition of gateroad entries, along with the caved materials permeability and porosity changes as the longwall face advances, determine the resistance of the airflow pathways within the ...

  • Characterization of Accidental Chemical Releases

    The 1990 Clean Air Act Amendment (CAAA) section 112 (r) Prevention of Accidental Releases requires the United States Environmental Protection Agency (EPA) to establish measures for owners and operators of facilities processing or handling hazardous materials to prevent accidental releases of regulated substances and other extremely hazardous materials to the air. Additionally, it requires the ...

  • Dynamic Simulation of Volatile Compound Transient Events at WWTPS

    ABSTRACTTransient or intermittent releases of specific volatile or semi-volatile organic compounds are not managed well by existing predictive fate models such as TOXCHEM+ or Water9 because they are based on steady-state conditions. In this paper, two scenarios for treatment of transient organic compound concentrations are studied using dynamic simulation: ...

  • Water infrastructure security against Al Qaeda`s revenge for the death of Bin Laden
