Non-Methane Cutter (NMC) Method

Metoda NMC (z izločevalnikom ne-metanov)

concw/o= HC concentration with CH4 bypassing the NMC

concw/o = koncentracija HC, če teče CH4 mimo NMC

concw/o= HC concentration with C2H6 bypassing the NMC

concw/o = koncentracija HC, če teče C2H6 mimo NMC

Non-Methane Cutter Method (NMC, Figure 10)

Metoda z izločevalnikom ne-metanov (NMC, Sl. 10)

concw= HC concentration with C2H6 flowing through the NMC

concw = koncentracija HC, če teče C2H6 skozi NMC

concw= HC concentration with CH4 flowing through the NMC

concw = koncentracija HC, če teče CH4 skozi NMC

To balance the flow through the NMC and the by-pass.

Flow diagram for methane analysis with the non-methane cutter (NMC)

Shema poteka pri analizi metana z izločevalnikom ne-metanov (NMC)

HC(w/oCutter)= HC concentration with the sample gas bypassing the NMC

HC(w/o Cutter) = koncentracija HC, če teče vzorčni plin mimo NMC

Učinkovitost izločevalnika ne-metanov (NMC, samo motorji na zemeljski plin)

HC(wCutter)= HC concentration with the sample gas flowing through the NMC

HC(wCutter) = koncentracija HC, če vzorčni plin teče skozi NMC

Methane calibration gas shall be flown through the FID with and without bypassing the NMC and the two concentrations recorded.

Kalibracijski plin metan se spusti skozi FID z in brez obvoda NMC, obe koncentraciji pa se zapišeta.

The NMC is used for the removal of the non-methane hydrocarbons from the sample gas by oxidising all hydrocarbons except methane.

Izločevalnik ne-metanov NMC se uporablja za odstranjevanje ne-metanskih ogljikovodikov iz vzorca plinov tako, da oksidira vse ogljikovodike razen metana.

Ethane calibration gas shall be flown through the FID with and without bypassing the NMC and the two concentrations recorded.

Kalibracijski plin etan se spusti skozi FID z in brez obvoda NMC, obe koncentraciji pa se zapišeta.

The cutter oxidises all hydrocarbons except CH4 to CO2 and H2O, so that by passing the sample through the NMC only CH4 is detected by the FID.

Izločevalnik vse ogljikovodike razen CH4 oksidira v CO2 in H2O, tako da FID ob prehodu vzorca skozi NMC zazna samo CH4.

The determination of the non-methane fraction shall be performed with a heated NMC operated in line with an FID as per section 3.3.3 by subtraction of the methane from the hydrocarbons.

Določanje ne-metanske frakcije se izvaja z ogrevanim izločevalnikom ne-metanov (Non-Methane Cutter - NMC), ki deluje podobno kot FID iz točke 3.3.3, z odštevanjem metana od ogljikovodikov.
