Foreword

GB/T 11060 "Determination of sulfur compounds in natural gas" is divided into five parts. --- Part 1. Determination of hydrogen sulfide content by iodometry; --- Part 2. Determination of hydrogen sulfide content with methylene blue method; --- Part 3. Determination of lead acetate reaction rate of hydrogen sulfide content of the double optical path method; --- Part 4. Determination of total sulfur content by oxidation Microcoulometry; --- Part 5. Hydrogen Solutions - rate meter colorimetric determination of total sulfur content. This section GB/T 11060 Part 5.

1 Scope

This section provides the solution with hydrogen - Test methods for natural gas in the total sulfur content rate meter colorimetry. This section applies to the determination of total sulfur content of natural gas, the measurement range of 0.1 × 10-6 ~ 20 × 10-6 (φ), equivalent to about 0.1mg/m3 ~ 26mg/m3; and measurement range can be extended to higher concentrations by dilution. This part can be used as refined products such as Propane, butane, ethane, ethylene quality control analysis means. This section does not address all the safety issues related to its application. Before using this section, the user has the responsibility to develop appropriate safety and Health measures, and clarify the scope of its qualified.

3 Test principle

The sample at a constant rate into the flow of hydrogen within the hydrogen analyzer solution at a temperature of 1000 ℃ or more sample and hydrogen gas is pyrolysis, sulfur Compounds are converted to hydrogen sulfide (H2S). The reaction of hydrogen sulfide with lead acetate results read by a colorimetric reaction rate meter detection unit 10-6 (Φ).

4 Reagents and materials

4.1 Detection tape. Use appropriate size of lead acid impregnated filter paper analysis. 4.2 acetic acid (5%). The volume of water to 1 volume of glacial acetic acid is mixed with the 19 formulated as a 5% solution of acetic acid. Distilled water should be consistent with GB/T 6682 regulations Given two water technical requirements. 4.3 airtight syringe. 0.1mL and 0.5mL airtight syringe each one for the preparation of calibration standards. Volume measuring syringe Accuracy of 1% or higher. 4.4 equipped with a piston pump. 10L polypropylene cylinder, the cylinder has a freely movable piston with a silicone rubber "○" on the piston Ring, this ring need to use silicone lubricant lubrication. This tube is used by volume formulation (10-6, φ) or the reference standard samples. 4.5 sulfur carbon dioxide (COS). volume fraction of 99% of the COS standards vials, the bottle outlet connected with a needle valve. In the needle valve About 60cm polyethylene pipe connection, when the pipeline purged with COS, insert airtight syringe out of pure COS from the standard vial, this Operation should be carried out in a fume hood or in well-ventilated areas. In taking adequate odor control measures can also use other sulfur compounds Thereof. If each molecule of sulfur compounds containing two sulfur atoms, the sample volume can be reduced by half. 4.6 Hydrogen. the volume fraction of not less than 99.99% of the sulfur-free hydrogen. Note. When mixed with air, hydrogen has a very wide explosive limit.
