  • 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: ...

  • Hydrogen Sulfide Scrubber Systems in Hydrometallurgical Application

    Hydrogen Sulfide is a highly toxic and flammable gas. Being heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces. Although very pungent at first, it quickly deadens the sense of smell, so potential victims may be unaware of its presence until it is too late. The lethal concentration for 50% of humans is 800ppm for 5 minutes of exposure. H2S is a by-product in many ...

  • Chemical Cleaning and Decontamination of Refinery and Petrochemical Distillation Equipment

    1. Abstract In refineries and petrochemical plants the equipment needs to be checked during planned shutdown. This can require several weeks of downtime, if columns, vessels, heatexchangers and tanks have to be drained to remove deposits and armful gases such as hydrogen sulfide, benzene and other volatile hydrocarbons. Formation of iron sulfide is very common in oil refineries and ethylene ...

  • TOTALOX Odor Eliminator: The Two Step Treatment in One Package - Case Study

    Collection Systems Are Tough! With miles of pipe and multiple pumping stations, managing the complexity of a wastewater collection system is a full time job. The main task is to maintain the system and keep it flowing. But also near the top of that task list is preventing nuisance odors. When the phone starts ringing, you become a detective. First, you have to find the site or sites ...

  • 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-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 ...

  • 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 ...

  • Maximize the coating life-cycle in severe wastewater environments

    In 2005, the American Society of Civil Engineers awarded a grade of D- to the nation’s wastewater systems based largely on the deterioration of sewage collection systems. That same year, the Bossier City Public Utilities Department in Louisiana restored a 5,000 square foot lift station using a 100 percent solids epoxy mortar system specifically designed to protect concrete in severe wastewater ...

  • Air Monitoring for the Gulf Oil Spill

    Ambient air monitoring is a priority in the ongoing efforts to contain and manage the oil spill from the Deepwater Horizon in the Gulf of Mexico. The following provides information about the kinds of airborne contaminants that are currently being monitored in the Gulf, how they are collected and how they are analyzed. For a given project, a suitable sampling plan – developed by ...


  • MIOX bringing green tech to fracking

    Water purification firm MIOX Corp. is diving deep into the bowels of the oil and gas industry. The Albuquerque company, whose purification systems are used worldwide to clean water for municipalities and commercial businesses, will apply its technology for the first time to reduce toxicity and improve the efficiency of fluids that oil and gas companies use for hydraulic fracturing to crack open ...

  • Mastering the Chaos

    Random packing consists of single pieces that are poured into separation columns and form a chaotic structure. Now, Sulzer has developed a new generation of high-performance random packing that offers more uniformity of surface distribution within the packing volume. The example of a CO2 absorber shows the benefits. Columns with random packing are well established ...

  • 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 ...

  • Analyzing sulfur in soil and sediment with handheld XRF

    Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...

  • Microturbines, Gas Engines Link Biogas to the Grid

    OPPORTUNITIES to produce electricity from methane are being improved continuously as manufacturers introduce new and upgraded equipment to address market needs and varying characteristics of raw biogas.

  • Taming taste and odor (T & O) problems in a water treatment plant

    Taming Taste & Odor (T&O) Problems Some taste and odors are caused by mineral constituents in the water, e.g. excess chlorine and hydrogen sulfide. However the majority of taste and odor are the result of biologic activity. Spring turnover of lakes and algal blooms are responsible for Blue-green algae (Cyanobacterium), Green algae and diatoms that introduce filter clogging organisms ...
