WebThe Gas Research Institute (GRI) methods are used to calculate methane number, MN, and motor octane number, MON, of gas; the linear relation is useful in determining and comparing the knock resistance of high methane content natural gas. … WebThe methane number is an important property of natural gas. This value, which is calculated using an approach by the South West Research Institute, indicates the knocking resistance of the fuel; a methane number of 80 gives the same knocking behavior as a mixture of 20% hydrogen and 80% methane.

What does "methane %LEL equivalent" mean? - Honeywell

WebHigh methane numbers mean high knock resistance; high knock resistance, in turn, means high efficiencies and thus lower CO 2 emissions. If methane numbers are too low, knock may cause engine damage or lead to losses in efficiency and performance if engine operation has to be adjusted to avoid knocking combustion. A low methane number … WebMethane Number. Methane number (MN) is analogous to the octane number for gasoline and reflects the anti-knock behavior of natural gas. It is based on work at AVL in the 1970s where pure methane has MN=100 and pure hydrogen has MN=0. Hydrocarbons heavier than methane have MN < 100 and they tend to degrade the anti-knock characteristics of ... breakfast places in ward
