THC FID optimization and THC FID verification
A manufacturer may choose to measure the mass of total hydrocarbons (THC) on the ETC test instead of measuring the mass of non-methane hydrocarbons.
Combined mass of hydrocarbons and oxides of nitrogen (THC + NOx)
The THC FID shall be spanned and calibrated with span concentrations of propane, C3H8.
Euro VI drastically reduces the emission limits for nitrogen oxides (NOx), total hydrocarbons (THC), and particulate mass.
In general, total hydrocarbons are composed of mineral oils.
The diluted exhaust gases are analysed for carbon monoxide and total hydrocarbons.
References to hydrocarbons should be understood as references to total hydrocarbons in the following paragraphs:
In accordance with one aspect of the present invention, the measured total hydrocarbons are treated as unburned fuel (C8 basis) plus burning zone hydrocarbons (C1 basis).
In this case, the limit for the mass of total hydrocarbons is the same as shown in Table 2 for the mass of non-methane hydrocarbons.
The concentration value shall be determined to calibration gas tolerances by chromatographic analysis of total hydrocarbons plus impurities or by dynamic blending.
The concentration value shall be determined to calibration gas tolerances by chromatographic analysis of total hydrocarbons plus impurities or by dynamic blending.
The concentration value shall be determined to calibration gas tolerances by chromatographic analysis of total hydrocarbons plus impurities or by dynamic blending.
The concentration value shall be determined to calibration gas tolerances by chromatographic analysis of total hydrocarbons plus impurities or by dynamic blending.
Methods and systems are disclosed to determine total hydrocarbons from fluid-carrying fluids and solids from a geological formation during downhole operations.
u value of CNG for HC corresponds to CH2,93 (for total HC use u value of CH4).
The percentages are expressed in weight with respect to the total weight of the composition and the composition has a total hydrocarbon content lower than 0.5 per cent.
