  • Hydrogen Performance for Carrier Gas

    Owing to the worldwide helium shortage, many labs are facing supply difficulties of helium, one of the most commonly used carrier gases and as a consequence are facing rapid price increases. Many chromatography labs are therefore looking for alternative carrier gases and for many GC applications, hydrogen provides a good, in some cases better, alternative to helium. The perceived danger of having ...

  • GC/MS analysis of a complex sample in DCM using hydrogen carrier gas

    Labs worldwide have recently found that helium has been in short supply, leaving a number of labs without carrier gas. Added to this, helium prices have doubled over the past 10 years causing a number of labs to look into alternative carrier gases for GC, such as nitrogen and hydrogen. As well as lower price and unlimited availability, hydrogen has a number of potential advantages over helium, ...

  • 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 ...

  • Hydrogen-cooled electric generators case study

    Application Moisture contamination is measured in the hydrogen gas used to cool large stationary electric generators. Problem Hydrogen is used to cool the bearings and other rotating parts of large stationary electric generators. Hydrogen is the best choice for a cooling gas because of its unique combination of high thermal conductivity and low viscosity. In ...

  • Hydrogen Sulfide Continuous Emission Monitoring of Odor Control Systems

    ABSTRACT This paper discusses the use of the Sycamore Continuous Emissions Monitor (CEM) for monitoring Hydrogen Sulfide Gas concentrations within odor control systems. The CEM is configurable as a single, two or three point system and can measure from 5 ppb to 2 PPM, 0.1 – 20 PPM, and 0 – 200 PPM and is designed for monitoring of scrubbers, carbon adsorbers, biofilters and biotrickling ...

  • Hydrogen production through chemical looping using NiO/NiAl2O4 as oxygen carrier

    A new autothermal route to produce hydrogen from natural gas via chemical looping technology was investigated. Nowadays, 90% of the worldwide produced hydrogen comes from fossil fuels, the most common process being Steam Methane Reforming (SMR), which produces several kg of CO2 equivalent per kg of hydrogen. In classic SMR technology, most of the greenhouse gases are vented to the atmosphere. ...

  • Laboratory scale tests of coal-based hydrogen production with CO2 capture in the aspect of clean coal technologies

    In the light of continuously increasing oil prices as well as stronger environmental regulations, an important issue becomes finding an alternative to fossil fuels. Scientists agree that hydrogen seems to be an ideal, price-competitive and environment-friendly future energy carrier. One of the most effective methods of hydrogen production is the process of steam gasification of coal to ...

  • 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 ...
