Greenstars portable monitoring for CHP and flares case study
Greenstar's award-winning KTK landfill site in Kilcullen, Co. Kildare, is unusual in Ireland in that it has three gas engines feeding electricity to the grid and two flares. In Ireland, while flaring is common, engines are not. The flares are run in tandem with engines so that if an engine is ramped down for repair or service, the flare ramps up automatically. All are supplied by 122 landfill ...

Toxicity Assessment Using a Dilution Series
Toxicity, or more appropriately, inhibition, is a measure of the interference of a compound or compounds with biodegradation. Since inhibition usually is expressed as the interference with bioconversion of an oxygen-consuming reaction – or gas producing reaction in the case of anoxic or anaerobic reactions – it is essential that a biodegradable substrate be present when assessing toxicity of ...

Nitrogen Safety in the Lab
This blog explains why nitrogen gas generators are the safest way to supply nitrogen to your instrumentation and why they pose no danger, in terms of changing atmospheric levels of nitrogen or oxygen. The biggest danger to lab personnel is a rapid depletion of oxygen levels in the lab. Once the level of oxygen reduces to A nitrogen gas generator producing 32LPM of nitrogen would take over 20 ...

Nitro Beer Tastes Better
If you've ever remarked on the smooth creaminess of a pint of Guinness, you've picked up on the key difference in its carbonation: Nitrogen rather than carbon dioxide. Such "nitro" beers have become a trend in recent years, with major U.S. breweries and small startups alike offering nitro products. Nitrogen keeps bitterness in check and balances out the hops to make drinkable craft brews, but it ...

Gas Safety in Confined Spaces
Introduction A confined space is any space large enough for someone to enter and perform assigned work, which has limited means of entry or exit, and which is not designed for continuous worker occupancy. This covers just about every industry, including utilities, construction, hydrocarbon exploration and processing, petrochemicals, marine, agriculture, food processing and brewing, as well as ...

Chemie Technik - Use of Nitrogen Generators in the Oil and Gas Industry
Nitrogen Production In-House Anyone who produces or processes oil and gas requires nitrogen – be it for avoiding explosions or for treating and de-oiling formation water. To ensure an uninterrupted supply, it can be worthwhile to produce such gas on-site using nitrogen generators. Two examples from Russia and Austria attest to this. The oil refinery in Orsk, Russia, is located almost 2,000 ...

Biodegradation Tests for Wastewater Samples
Biodegradation Tests for Wastewater Samples Biodegradation tests usually involve comparison of the oxygen uptake of a test sample – or gas production for anoxic or anaerobic tests – to that for a readily biodegradable control substrate (usually acetic acid, ethanol, or aniline). While biodegradation characteristics can vary among chemical types and wastewater sources, typical patterns are shown ...

Water quality measurement extreme
Background The characteristics of the Rio Tinto in the south-west of Spain, near Sevilla, are his ruby colour and the extremely sour pH-value between 0 and 2 pH-units. The river carries a mixture between poisonous heavy metals like copper, nickel, arsenic, iron and cadmium, dissolved in high-percent sulphuric acid. It’s not proved where these unusual conditions come from. As per current ...

Don’t Let the Pressure of Compressed Gas Get to You
What’s at Stake? The hazards associated with compressed gas include oxygen displacement, fires, explosions, toxic effects from certain gases, reactivity and projectile concerns. What’s the Danger? An employee was killed when a compressed gas cylinder turned into a projectile because its valve was knocked off. Another worker suffocated after entering a space filled with nitrogen ...

Thermal spray gas flow control
How to Achieve a Consistent Flame and Avoid Problems High Velocity Oxygen Fuel (HVOF) thermal spray technology has evolved and advanced recently through the use of more sophisticated controls and design. In particular, the ignition and control of the flame has benefited from the use of actively controlled flow rates which deliver steady, consistent, and programmable flame characteristics and gas ...

Methane conversion to higher hydrocarbons over copper loaded BZSM-5 in the presence of oxygen
The direct conversion of methane to higher hydrocarbons either over metal catalyst or zeolite has not been successful so far in achieving the methane conversion with higher hydrocarbons selectivity within the economic range due to oxidation of the product. The present research aims at improving the performance of BZSM-5 catalyst with the addition of copper. Catalytic behaviours at different ...

Emerging Waste Conversion Technologies
Today, people and companies are more aware and concerned about the environment than ever before. Everyone is looking for ways to reduce waste or convert organic waste into something more useful. The Federal Government has introduced a renewable energy policy and is continuing to fund for new waste conversion technology. It is now important for local governments to portray their cities and towns ...

Thermal hydrolysis of the lipid and protein fractions of wastewater sludge: implications for digester performance and operational considerations
ABSTRACT Thermal hydrolytic pretreatment of wastewater sludge followed by mesophilic anaerobic digestion poses significant benefits in terms of sludge minimization and pathogen reduction; however, high levels of volatile fatty acids (VFA) in digester effluent reveal an interruption in the efficient conversion of organic material to methane gas. Residual soluble chemical oxygen demand (COD) not ...

Application of nanocrystalline metal oxide gas sensors for air quality monitoring
Increasing concern regarding health effects caused by air pollution, together with the limited spatial resolution achievable with conventional monitoring stations, have driven efforts to develop inexpensive metal oxide gas sensors for air quality measurements. The sensing mechanism is dependent on physicochemical reactions between adsorbed gas molecules and oxygen species on the oxide surface, ...
