Thermal oxidation of coal mine ventilation air methane
Methane is a powerful greenhouse gas and the principal component of natural gas. Coal seams often contain significant quantities of methane, and underground coal mines must ensure that methane released into the mine during coal extraction does not build to dangerous levels. This is accomplished in part through the use of large-volume ventilation systems that remove methane from the mine and rel...
متن کاملCoal-Packed Methane Biofilter for Mitigation of Green House Gas Emissions from Coal Mine Ventilation Air
Methane emitted by coal mine ventilation air (MVA) is a significant greenhouse gas. A mitigation strategy is the oxidation of methane to carbon dioxide, which is approximately twenty-one times less effective at global warming than methane on a mass-basis. The low non-combustible methane concentrations at high MVA flow rates call for a catalytic strategy of oxidation. A laboratory-scale coal-pac...
متن کاملDrought Analysis of Alvand Boundary River Using Remote Sensing Data
Extended abstract 1- Introduction The study of the behavior of rivers in the arid and dry areas is one of the most important tasks in the country. Because the area has increased the effects of drought due to the sensitivity of the area and rainfall shortage, it causes changes in the flow and sediment regime, water resources, agriculture, and so on. Since plants react more precisely to t...
متن کاملrepository copy of Coal mine ventilation air methane combustion in a catalytic reverse flow reactor : Influence of emission humidity
7 The role of the humidity content on the performance of catalytic reverse flow reactors (RFR) for the 8 abatement of methane emissions from coal mines is studied in this manuscript. It has been 9 demonstrated that this technique is very useful for the abatement, and even upgrading, of these 10 emissions. However, the effect of humidity on the reactor performance has not been addresses yet, 11 ...
متن کاملField Validation of Remote Sensing Methane Emission Measurements
Area sources are a key contributor to overall greenhouse gas emissions but present a particular challenge to emission measurement techniques due to the heterogeneous nature of the sources. A new Controlled Release Facility (CRF) has been developed that is able to recreate in the field both the distribution and rate of emissions seen in actual industrial applications. The results of a series of ...
