Hydrogen Sulfide (H2S) monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Hydrogen sulfide is the chemical compound with the formula H2S. H2S is colorless, toxic and flammable and is responsible for the foul odour of rotten eggs and flatulence. Hydrogen sulfide often results from sulfur reducing bacteria in nonorganic matter (in the absence of oxygen), such as in swamps and sewers (anaerobic digestion). H2S also occurs in volcanic gases, natural gas and some well waters.

Aqua M300 Intelligent Geophone

by F.A.S.T. GmbH     based in Langenbrettach, GERMANY

With the Aqua M300 leak detectors have a multifunctional tool to Pinpoint or Pre-locate leakages and to trace pipes in conjunction with a PWG. The biggest advantage compared to other related products are the 256 analogue and digital filters which enables the user to shut off disturbing noises very precisely. Also the extension for H2 tracer gas comes without competition and makes this device a essential tool for leak detectors.

Beverage Analysis

by Hiden Analytical     based in Warrington, UNITED KINGDOM

Hiden gas analysis systems provide for high sensitivity, wide dynamic range, real-time analysis of almost any gas/vapour. Hiden’s application specific gas analysis systems are tailored to meet the specific application requirements, & include a range of special sampling, vacuum pumping and vacuum accessories. Hot zone sampling accessories are included for evolved gas analysis from furnaces, & thermo gravimetric analysers, TGA, for example. Thermal analysis methods are vital for catalysis characterization. For thermal analysis including TPD/TPO/TPR studies, Hiden gas analysis systems include enhanced pumping for hydrogen and special close coupled sampling to the TPD/TPO/TPR reactor for optimum thermal analysis response. In Biogas applications the simultaneous analysis of H2S, CO2, water vapour & CH4 in the PPM to 100% concentration range provides vital information for process development and process monitoring

Gas Detection Solutions for Sour Gas

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

The sour (H2S) content of hydrocarbon fields worldwide is increasing, and many natural gas fields have very high H2S – sometimes in excess of 50%. H2S is extremely dangerous because, although people can smell it at low levels (about 5 ppb) it does not smell much worse at the exposure limit value of 10 ppm or at potentially fatal levels in excess of 100 ppm. Therefore smell is an unreliable means of determining dangerous levels. Existing H2S point sensors are maintenance intensive, slow to respond and provide limited coverage. Most H2S sensors do not work reliably in hot or cold weather, or in humid marine environments.

Total sulfur measurement for sulfur compounds in CO2 for food & beverage industry

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The BevAlert Model 8900 provides a total sulfur measurement for sulfur compounds in Carbon Dioxide. The measurement includes organic sulfides, Sulfur Dioxide, Carbonyl Sulfide, and Hydrogen Sulfide. The instrument is utilized by Specialty Gas Manufacturers and the Food and Beverage Industry to monitor sulfur compounds in CO2 used in carbonated beverages.

Waste water treatment plants Screening area: stripping

by Chromatotec Group     based in Val de Virvée, FRANCE

Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. To ensure the safety of operatives in the screening building/area of waste water treatment works an H2S analyzer has been installed in the main building to complement the protection provided by individual monitors. Chromatographic measurements show that other sulfurous compounds including Methylmercaptans are present in the air in addition to H2S.

Odour Monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Measurement of odours from pulp & paper, feedlots and natural sources is challenging and requires careful selection of instrumentation. Ecotech offers a complete monitoring solution designed for this application. Odours are one of the most common sources of air pollution complaints and may be due to a wide variety of sources from rotting vegetation, animal feedlots, pulp and paper manufacturing, sewerage treatment facilities etc. The measurement of odours is extremely difficult due to the variety of sources of odour and the often very low ppb concentrations that produce odour. However, some industries and applications have a known source of odour resulting from compounds such as mercaptans, hydrogen sulphide, ammonia, typically from industries such as pulp and paper manufacturing, fertiliser production or natural sources such as rotting vegetation. Ecotech is able to offer extremely sensitive instrumentation and systems that enables the low ppb monitoring of these species down to 1 ppb, fully integrated with our data evaluation and reporting software.

Measurement of hydrogen sulfide & carbon disulfide in air for continous emission monitoring

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The Series 8900 Hydrogen Sulfide and Carbon Disulfide Analyzer provides direct measurement of H2S and CS2 in ambient air. This instrument is utilized for continuous emission monitoring. The Series 8900 H2S and CS2 Analyzer employs a Photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the H2S, CS2, and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. H2S and CS2 are separated from potentially interfering components on the analytical column and elute to the detector for analysis.

Water Treatment Solutions for Hydrogen Sulfide

by Adedge Water Technologies, LLC     based in Buford, GEORGIA (US) (USA)

Sulfates and hydrogen sulfide are both common nuisance contaminants. Although neither is usually a significant health hazard, sulfates can have a temporary laxative effect on humans and young livestock. Sulfates also may clog plumbing and stain clothing. Hydrogen sulfide produces an offensive `rotten egg` odor and taste in the water, especially when the water is heated.
