Laboratory measurement and modelling of coal permeability with different gases adsorption
Adsorption of gas on coal will induce coal matrix swelling. Under reservoir conditions these strain changes affect the coal permeability. A series of laboratory measurements of gas permeability of a coal sample from Qinshui basin has been conducted, using a new apparatus developed for measuring coal permeability with various gases adsorption, by use of the transient pulse decay technique. Results ...

Characterization of methane flux from photosynthetic oxidation ponds in a wastewater treatment plant
Photosynthetic oxidation ponds are a low-cost method for secondary treatment of wastewater using natural and more energy-efficient aeration strategies. Methane (CH4) is produced during the anaerobic digestion of organic matter, but only some of it is oxidized in the water column, with the remaining CH4 escaping into the atmosphere. In order to characterize the CH4 flux in two photosynthetic ...

Gas Detection and Monitoring Systems
In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

Trees Shaping the Global Greenhouse Gas Dynamics
There is a vast body of literature on trees’ role in tackling the greenhouse effect, especially by reducing CO2 emissions. As is known, during the Northern winter, as our green friends hibernate, the CO2 levels skyrocket globally. When summer finally arrives in the North, forests get back to work and absorb a huge cloud of CO2, bringing the levels down. Trees, in other words, have always ...

CH4 Monitoring
Methane has a direct influence on climate change as well as an indirect effect on human health, plant yield, and productivity due to its role as an important precursor to ground-level ozone formation. Therefore, CH4 monitoring is an efficient way to detect the buildup of CH4 levels and take necessary actions. This article covers information on methane gas, its sources in the ambient air, ...

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 ...

Application of CH4 gas sensor
introduction Methane gas is an odorless, colorless, highly flammable gas commonly found in natural gas, biogas, and landfill gas. It is also a potent greenhouse gas that contributes to climate change. Therefore, monitoring and detecting methane gas leaks is critical to prevent potential hazards and environmental damage. The CH4 gas sensor detects and measures the concentration of methane gas in ...

Monitoring Methane Emissions from Agriculture and Dairy Farming
Methane (CH4) is the second most prevalent greenhouse gas emitted from human activities. In 2014, CH4 was responsible for around 11 percent of all US greenhouse gas emissions caused by human actions. Methane is emitted by a range of natural sources such as marshlands, leakage from natural gas systems and livestock farming [1]. Domestic livestock such as cattle, sheep and goats, produce ...
