  • 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 ...

  • Gas detector communication technology for offshore oil and gas platforms

    In few applications is safety as important as on offshore oil and gas platforms. Explosive hazards from hydrocarbon gases and vapours are an ever-present risk, whilst toxic hydrogen sulphide gas and depleted oxygen environments can pose significant risks to personnel. Gas detectors are therefore essential to provide dependable early warning of gas hazards. Gas detectors are permanently installed ...

  • Gas Detection in Recreation Facilities: Can the same detector work for pools and arenas?

    It is not uncommon for the same recreational facility to offer both skating and swimming amenities, two very different environments with different potential gas hazards. Given the fact that there is a possibility of 6 different types of gas to monitor and the large area between the two types of facilities, a single detector will not provide the monitoring requirements for both areas. It is ...

  • Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

    Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...

  • Improved HF monitoring in Primary Aluminium Smelters with Laser Gas Detectors

    Primary aluminium smelting generates large amounts of hydrogen fluoride gas (HF). Concerns for worker safety and ambient air quality require that HF be monitored at several locations in smelters. Historically, a variety of methods have been used for HF monitoring. Cassette samplers and wet chemistry techniques, coupled with complex and expensive ...

  • Honeywell gas detectors serve emergency backup role in U.S. rocket launch to destroy spy satellite

    A U.S. Standard Missile 3 (SM-3) enabled by Honeywell technology recently shot down a rogue U.S. spy satellite in space carrying over 1000 pounds of hydrazine, a highly toxic chemical used in rocket fuel. Meanwhile, Honeywell Analytics gas detection technology played a critical backup role in the operation: the company’s Single Point Monitor (SPM) was deployed at over 25 FEMA locations throughout ...

  • 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: ...

  • Gas safety in confined spaces

    An engineer repairs buried cables; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face a common danger, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited.  ...

  • Stack gas VOC monitoring

    POLLUTION S.r.l. manufactures POLARIS FID analyzer, a cutting-edge technology for the measurement of total hydrocarbons in ambient air and stack emission monitoring in accordance with EN 13526 and EN 12619. This analyser is based on Flame Ionization Detection (FID), a reference method technique to measure total hydrocarbons (THC, VOC, TOC). Polaris FID is a very handy instrument because it allows ...

  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • Laser gas detection is now cheap, fast and reliable

    Laser based gas detectors are now being used in a wide variety of applications for process and quality monitoring, and safety and environmental compliance. The reasons are that laser detectors are more reliable and less expensive than alternative solutions. Laser detectors combine semiconductor tunable diode lasers (TDL) and optical fibres developed by the telecommunications industry with ...

  • 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 ...

  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • New Process Gas Analyzer for the Measurement of Water Vapor

    KEYWORDS TDLAS, WMS, Laser Spectroscopy, Water Vapor Measurement, Gas Analyzer ABSTRACT A new analyzer for the measurement of water vapor concentration based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) was developed. The water-vapor line at 1854-nm was selected for the measurement, and the performance of the system was evaluated on different ...

  • Identifying Leaks from Natural Gas Pipelines at a Safe Distance

    The use of natural gas, of which methane is the principle component, is increasing worldwide. According to the American Petroleum Institute methane meets 24% of U.S. energy demand and heats over 50% of all U.S. households. It also has many industrial uses, such as the manufacture of chemicals like ammonia, methanol, butane, ethane, propane and acetic acid; it is also an ingredient in products as ...

  • A Comparison of Point Sensors and Open Path Monitors For Toxic Gas (esp. HF) Monitoring

    Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...
