Natural gas - Determination of sulfur compounds
Part 7. Determination of total sulfur content by combustion method Linge Nai
1 Scope
This section specifies the test method for the determination of total sulfur content of the natural gas used Linge Nai combustion method.
This section applies to the determination of total sulfur content of natural gas measurement range 0.5mg/m3 ~ 1000mg/m3. Total sulfur-containing absorption solution
Higher than 0.1mg, choose visual indicator titration; absorbing liquid total sulfur content below 0.1mg, choose turbidity titration.

3 PRINCIPLE OF THE METHOD
A volume of the sample gas with air at atmospheric pressure in a glass burned in the combustor. Oxides generated by absorption of the hydrogen peroxide solution
And converted to sulfuric acid. According to the test gas sample in low sulfur content, select the measurement indicator visually titration or turbidimetric titration.
4 Reagents and materials
Use only analytical reagent and distilled water or equivalent purity water analysis.
4.1 Hydrogen peroxide, 10% (by mass) aqueous solution. no sulfur as a sulfur oxide absorbing liquid.
4.2 Activated Carbon. combustion air for the adsorption of sulfur impurities.
4.3 absorbed hydrogen hydroxide, 30% (by mass) aqueous solution. for purifying the combustion air.
5 device
Apparatus is shown in Figure 1.
