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

Measurement of hydrogen in fuels for oil & gas industry

by Oxford Instruments plc     based in Abingdon, UNITED KINGDOM

The combustion properties of fuels are key to the efficient and safe operation of engines used in machinery and plant. One important way to measure the combustion properties of a fuel is by its hydrogen content. The measurement of hydrogen content is widely used for the characterisation of aviation fuel but with the increasing costs of all fuels and the greater incentives for fuel adulteration, this test is increasingly being adopted for non-aviation applications. Our benchtop NMR analyser MQC-23 system is widely used for the measurement of hydrogen in fuels in accordance with ASTM D7171-05.

Methane Sensing for Coal Mining

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Application: The majority (around 60%) of the coal seams currently being extracted worldwide are so far underground that open cast mining cannot take place and, therefore, underground mining techniques need to be used. Consequently, workers have to enter and work in confined spaces. One of the major problems that this creates is the dangers from Methane (CH4) gas which occurs in Mine gas.

Moisture Monitoring for Hydrogen Annealing Ovens

by Moisture Control & Measurement Ltd     based in Wetherby, UNITED KINGDOM

High moisture content in hydrogen gas used in annealing furnaces causes oxidation of the metal to occur, thus resulting in an undesirable surface finish on the product

Gas Detection Solutions for Hydrogen Fluoride (HF) Safety

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

Hydrogen Fluoride (HF) is a very useful chemical used in a variety of industries. However, HF is highly toxic with potential fatal consequences with exposure to humans, so facilities that make or use HF should exercise great care. Nevertheless, there is always the risk of leaks from process elements such as valves, pump seals and storage vessels. Tanker loading, transporting and unloading operations also provide opportunity for HF releases. Industrial processes that make or use HF typically have arrays of point sensors distributed throughout the unit. However, these sensors are maintenance intensive and have relatively slow response times. In addition, a point sensor will not detect an HF release unless it is located directly in the area of that release. Electrochemical HF sensors also respond to chlorine, ammonia, and sulfur dioxide, resulting in false alarms.

Agitation and mixing solutions for chemical

by National Oilwell Varco     based in Dayton, OHIO (USA)

Applications within the Chemical Processing Industry (CPI) are extensive.  Thousands of products are produced, synthesized, reacted, and treated to help produce a variety of products.

Continuous emissions monitoring for steel mills

by Opsis AB     based in Furulund, SWEDEN

The nature of steel manufacturing processes places severe limitations on the monitoring methods that can be used. Aggressive environments combined with high levels of particulates and gases make the choice very limited.

Hydrogen Fluoride (HF) Monitoring in Air

by Unisearch Associates Inc.     based in Concord, ONTARIO (CANADA)

Hydrogen Fluoride (HF) is a colorless gas that is used extensively in industrial applications. Fluoride monitoring is especially needed for aluminum plants that need to convert HF into fluorine for use in their processes. Any HF that escapes is a cost to the plant, so an HF analyzer is essential to keep track of and prevent the losses.

Industrial Solution for metallurgical, mining & chemical

by Macrotek Inc.     based in Markham, ONTARIO (CANADA)

Hydrometallurgical extraction of metals such as Nickel and Cobalt generate emissions of lethal gases such as Hydrogen Sulphide or Hydrogen Chloride. Macrotek has designed and supplied many systems to capture and treat these gases. In most cases the by-product is returned back to the process for reuse. Pyrometallurgical extraction of metals from sulphur containing ores generate large amounts of SO2 and particulate emissions. Macrotek has designed integrated systems to capture particulate and neutralizes SO2.

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.

Water Testing for Textile Manufacturing

by Myron L Company     based in Carlsbad, CALIFORNIA (USA)

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

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.
