Fugitive gas emissions are emissions of gas (typically natural gas, which contains methane) to atmosphere or groundwater [1] which result from oil and gas or coal mining activity. [2] In 2016, these emissions, when converted to their equivalent impact of carbon dioxide , accounted for 5.8% of all global greenhouse gas emissions .
They are collapsible, flexible storage bladders (also known as tanks) that provide transport and storage (temporary or long term) for bulk industrial liquids such as fuels. Standard fuel bladder tanks sizes range from 100-US-gallon (380 L) to 200,000-US-gallon (760,000 L) capacities and larger.
It was designed in Germany in the 1930s for military use to hold 20 litres (4.4 imp gal; 5.3 US gal) of fuel. Three handles allow for two people carrying a full can or one person handling an empty can. The basic design is still in use today although construction is often of high density polyethylene. [1]
Soil gas surveys can be used as a preliminary screening procedure to determine the extent of contamination due to volatile components. Some of the current strategies to detect and analyze NAPL presence include gas chromatography, high pressure liquid chromatography, and time domain reflectometry.
A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas (coal gas or formerly also water gas) is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a movable cap.
In the first example, we will show how to use a mass balance to derive a relationship between the percent excess air for the combustion of a hydrocarbon-base fuel oil and the percent oxygen in the combustion product gas. First, normal dry air contains 0.2095 mol of oxygen per mole of air, so there is one mole of O 2 in 4.773 mol of dry air.
Cascade storage is used at compressed natural gas (CNG) fueling stations. Typically three CNG tanks will be used, and a vehicle will first be fueled from one of them, which will result in an incomplete fill, perhaps to 2000 psig for a 3000 psig tank. The second and third tanks will bring the vehicle's tank closer to 3000 psi.
Boilover onset mechanism. The extreme violence of boilovers is due to the expansion of water from liquid to steam, which is by a factor of 1500 or more. [3] In practical storage scenarios, the presence of water under the burning fluid is sometimes due to spurious accumulation during plant operation (e.g., rainwater entering a seam in the tank roof, off-specification products from the source ...
