  • Developing Technologies to Detect Hydrogen Sulfide (H2S) Gas

    Abstract Hydrogen sulfi de (H2S) gas can cause nausea, headaches, unconsciousness, and death. Industries struggle to detect this deadly substance before it harms workers or communities. Safety system manufacturers have developed detectors that sense the H2S quickly and accurately. This paper illustrates, in general terms, considerations in effective placement of H2S detectors: ...

  • Use of biocatalysts to reduce hydrogen sulfide emissions from lagoons and landfills

    Emission of odors from ponds and lagoons occurs due to aerobic and anaerobic decomposition of organic solids to release hydrogen sulfide, ammonia, and other organic by-products.  Aerobic biodegradation occurs near the water-air interface, where diffusion of oxygen occurs, while anaerobic degradation prevails mainly near the bottom of the pond or lagoon, where there is low or no dissolved oxygen ...

  • 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 ...

  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

  • Analysis of Natural Gas Products by GC / TCD / FID

    The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific Model 910 ...

  • Follow toxic gas standards for a smoother project

    Toxic gases, such as Hydrogen Sulfide and Sulfur Dioxide, can injure and kill quickly. Therefore, mitigation of these hazards must be fast and sure. The United States Occupational Safety and Health Administration (OSHA) and other authorities take detection of these gases very seriously. The American National Standards Institute/ American Petroleum Institute (ANSI/API) and ISA industry standards ...

  • New air quality rules challenge oil & natural gas industry

    EPA Administrator signed a suite of proposed new air regulations affecting both the Production/Processing and Transmission/Storage sectors of the oil and natural gas industry. The proposed rules mandate the use of emission controls as well as work practices through two different air regulatory programs – New Source Performance Standards (NSPS) and National Emissions Standards for Hazardous ...

  • Not All Hazards are the Same: Design considerations for matching flame and gas hazards to detector technologies

    Not all flame and gas hazards in facilities are the same, therefore the detection technology chosen should be specific to the type of hazard to be detected. How do users select technologies to see certain fires or detect certain gases? The intent of this paper is to give a broad introduction to the selection and use of flame and gas detector technologies. We will answer questions such as these: ...

  • Better Performance at Lower Cost - Honolulu case study

    Business OverviewThe City of Honolulu operates the Halekou Lift Station which pumps, on average, 35,000-50,000 gallons per day which, in turn, feeds into the Aikahi Wastewater Treatment Plant. The lift station is located in the Kaneohe neighborhood on the windward side of Oahu. The city is, of course, an extremely attractive tourist location, so when area residents began complaining of ...

  • Aerating recycled water on mushroom composting sites affects its chemical analysis and the characteristics of odor emissions

    Recycled water (RW) containing compost leachate can be a potent source of foul odor on mushroom composting sites. Samples of RW were repeatedly collected from storage tanks and pits of 14 mushroom composting sites in England and Ireland. Relationships between the effects of submerged aeration of the RW, the chemical and microbial characteristics of the RW, and the odors emitted were investigated. ...

  • Direct and indirect effects of petroleum production activities on the Western Fence lizard (Sceloporus occidentalis) as a surrogate for the dunes sagebrush lizard (Sceloporus arenicolus)

    The dunes sagebrush lizard (Sceloporus arenicolus) is a habitat specialist of conservation concern limited to shin oak sand dune systems of New Mexico and Texas. Because much of the dunes sagebrush lizard's habitat occurs in areas of high oil and gas production, there may be direct and indirect effects of these activities. We used the congeneric Western fence lizard (Sceloporus occidentalis) ...

  • Wastewater force main management – internal corrosion survey using inline methods

    In our first post about Wastewater Force Main Management, we looked at how preliminary analysis helps operators develop a plan for managing their system. After completing this process, operators can begin putting the plan into action with preliminary surveys on specific force mains. For those at WEFTEC, you can visit Pure ...

  • Odor Eliminators For Roof Top Vents Often Called Stink-Pipes

    Every state, city, and village either has odor ordinances or treats obnoxious odors perceptible beyond property lines as public disturbances/nuisance. All plumbing vent stacks produce odors unless they fitted with a filter. OSHA warns that levels of 300-ppm (H2S) cause the olfactory nerve to lose sensitivity. At first a “rotten egg” odor is detected but on the second or third breath the odor ...

  • Wastewater-Solids Dewatering Odor Control - Case Study

    Background The Milan Wastewater Treatment Plant, located just south of Moline, Illinois, is a 1.7 MGD (6,434 m3/day) activated sludge facility with an average wastewater flow of 700,000 gpd to 800,000 gpd. This facility dewaters primary sludge using a belt filter press (Figure 1). The press operates an average of three times per month, 8 hours per day at a pump rate of 100 gpm. The ...

  • 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 ...

  • Odor Control Advances at Composting Facility

    The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility ...
