  • What are the main indicators of water quality?

    “Water is the driving force of all nature;” so said Leonardo da Vinci. The survival of our planet depends on the availability of water and the condition that it is in. It is therefore vital to make sure that it is able to provide a hospitable environment for those that live in it, and is free from harmful levels of substances for those that drink it. Not ...

  • Trends in bio-hydrogen generation - a review

    This paper reviews the research work carried out in bio-hydrogen generation from a renewable source, namely biomass. Bio-hydrogen production has several advantages when compared to photo-electrochemical or thermo-chemical processes due to the low energy requirement and investment cost. Hydrogen seems to be the future energy carrier by the virtue of renewable. Bio-hydrogen production processes ...

  • 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 ...

  • Generator gas analyzer for monitoring of hydrogen cooled turbo generators

    Hydrogen cooled generators require safety measures that reliably prevent the formation of explosive gas mixtures during normal operation as well as maintenance periods. Thermal conductivity technology based gas analyzers are used for that task. A standardized CALOMAT 6 analyzer system - Set GGA - has been especially designed for this measuring task. Regarding redundancy and explosion ...

  • The hydrogen loop: the means for making the hydrogen economy realistic

    The hydrogen economy has already started with the introduction of the Ovonic nickel metal hydride battery, which has enabled the rapid growth of hybrid vehicles. Reversible storage of hydrogen in a solid hydride permits the entire loop of hydrogen generation, storage and use, all of which have been placed some time in the future. It is often stated that the hydrogen infrastructure does not exist ...

  • Detect Hydrogen Gas and Flames

    Under day-to-day conditions, people cannot see, smell, or taste the presence of hydrogen gas. Hydrogen, however, is very flammable and requires only a small amount of energy to ignite. In fact, if leaking from a pipe at a high enough pressure, hydrogen gas can self ignite without the aid of an external energy source. Working together, ...

  • Hydrogen Purification Methods

    Hydrogen Generators that are utilised to provide Carrier Gas for GC and GC/MS applications employ many technologies to provide high purity hydrogen. Here were look at the various methods used to purify hydrogen. Three using PEM (Proton Exchange Membrane), combined with various purification techniques, and the fourth using a combined Palladium Electrolyser.   ...

  • 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 ...

  • What Nafion Membrane Thickness is Right for an Electrolyzer / Hydrogen Generation?

    Nafion membranes come in many different thickness and types. How do you know which to choose when designing an electrolyzer (hydrogen generator)? Choosing the proper ...

  • Seasonal and influent characteristic effects on hydrogen sulfide generation at a water reclamation plant

    Correlations between sulfide generation and seasonal influent wastewater characteristics were identified based on a long-term monitoring program in summer and winter at a water reclamation plant. During summer, the emission rates of hydrogen sulfide (H2S) from the liquid treatment processes increased substantially compared to those during winter due to the increased wastewater temperature. The ...

  • The hydrogen materials community: its history and current status in the World Hydrogen Movement

    This review briefly summarises the history of the hydrogen materials community as an important part of the World Hydrogen Movement. It analysis the history and current status of the interrelation between the Hydrogen Energy (HE) and Hydrogen Materials (HM) communities. During the last 15 years, great advances in this cooperation have come about, thanks to the thorough activities of the Permanent ...

  • ABS-181 Hydrogen Peroxide Enhancer

    Introduction The conventional sewer cleaning system can only bandaging the problems which cannot provide solution to prevent sewer line corrosion caused by toxic gases, organic constriction, deprived penetrating distance, generated large amount of hazardous organic and inorganic waste to increase environmental burden. The Objectives of the present invention is an aggressor method providing ...

  • Designing a sustainable hydrogen energy economy

    A general vision of a sustainable energy economy relying substantially on hydrogen produced from renewables is sketched as a potential solution to the twin global crises of climate change and depleting oil reserves. Core differences between this 'sustainable hydrogen economy' (SHE) and the original hydrogen economy (HE) proposed in the early 1970s are discussed. In transport, rather than posing a ...

  • Corrosion of Electronic Components by Hydrogen Fluoride

    Generation of hydrogen fluoride (HF) from fire suppression by some gaseous agents is a major concern, because HF causes corrosion. Without proper precautions, the HF corrosion damage to some electronic facilities can be significant. A study has been carried out to evaluate the corrosion effect of HF on electronic equipment. This article describes details of the corrosion study in terms of test ...

    LGR's Hydrogen Chloride Analyzer (HCl, H2O) provides sensitive measurements of HCl in ambient air or in industrial process flows (e.g., coal and cement exhaust streams) with extremely high precision and sensitivity. No longer do you have to spend a lot of money or wait a long time to measure HCl with extremely high sensitivity – LGR's HCl Analyzer provides measurements every second with ...

  • Precipitation of heavy metals from coal ash leachate using biogenic hydrogen sulfide generated from FGD gypsum

    Investigations were undertaken to utilize flue gas desulfurization (FGD) gypsum for the treatment of leachate from the coal ash (CA) dump sites. Bench-scale investigations consisted of three main steps namely hydrogen sulfide (H2S) production by sulfate reducing bacteria (SRB) using sulfate from solubilized FGD gypsum as the electron acceptor, followed by leaching of heavy metals (HMs) from coal ...

  • Photocatalytic hydrogen generation from water under visible light using core/shell nano-catalysts

    A microemulsion technique was employed to synthesize nano-sized photocatalysts with a core (CdS)/shell (ZnS) structure. The primary particles of the photocatalysts were around 10 nm, and the mean size of the catalyst clusters in water was about 100 nm. The band gaps of the catalysts ranged from 2.25 to 2.46 eV. The experiments of photocatalytic H2 generation showed that the catalysts ...

  • A method of calculating hydrocarbon generation history - hydrogen index method (TTPCI–IH method)

    The traditional TTI–Ro method uses virtinite reflectance as the indicator of the organic matter maturity, and then makes it a dominant parameter during the simulation of organic matter hydrocarbon generation history. However, this method only takes virtinite reflectance as a function of time and temperature, but ignores not only the influence of pressure and catalyst, but also the follow–up ...
