Natural gas - Determination of sulfur compounds
Part 11. The length of the colored test tube assay
Hydrogen sulfide content
1 Scope
GB/T 11060 provisions of this part of the test method for natural gas hydrogen sulfide content of the tube was measured by the length of the colored detection.
This section applies to the rapid determination of hydrogen sulfide gas content measurement range 0.5 × 10-6 ~ 0.4 (volume fraction).
NOTE. sulfur dioxide and mercaptans usually produces a positive interference, nitrogen dioxide and in some cases cause negative interference. Most tubes are detected with the elimination of certain stem
Prewash interference layer. Specific interference information can be found in test tube specification.
This section does not involve the use of all their security-related issues before using this section, the user has the responsibility to establish appropriate safety and security
Protective measures, and determine its suitability before use.
Principle 2
Manual piston pump or bellows pumping gas sample to at a flow rate controlled by filled with specially prepared chemicals
Qualitative test tube, a color change or chemical reaction between hydrogen sulphide colored and detection of the sample tube. When the volume of a sample
Timing detector tube is directly proportional to the length of the colored content of hydrogen sulfide in the sample. With the detector tube calibrated scale compared with the resulting
Color length converted to hydrogen sulfide content.
3 Instrument
3.1 shader length scale calibration and test tube
Sealed off both ends of the glass tube, seat tube and pump size match. Reagent layer tube, usually silicon coated with an active chemical substance
glue. It can produce significant changes in the color of the reagent layer in contact with a gas containing hydrogen sulfide in the sample. All known interfering substances should be detected
Pipe specification listed. Calibrated scale should be directly on the test tube, if the test tube to provide a separate calibrated scale, should be converted to sulfur
Identification of the other hydrogen content. Concentration of hydrogen sulfide should be calibrated scale associated with a coloration width.
3.2 detector tube pump
Manual piston pump or bellows-type pump. Each stroke should be able to sample through the detector tube 100mL volume deviation of ± 5mL.
Note. The test tube and detector tube pump supporting the use. Manufacturers test tube calibrated flow characteristics make it consistent with the detector tube pump. If different brands of pumps
And test tube mix will result in decreased accuracy of measurement results.
3.3 Gas sampling chamber
At atmospheric pressure gas sample evenly through any channel and the sample container detector tube and spaced from the surrounding air. In the gas supply valve and
Installed between the gas sampling chamber stainless steel needle valve (or pressure regulator) to control sample flow. Test tube during sampling, sample flow per
Min sample chamber volume of about 1 to 2 times, or at least a sampling chamber can be discharged.
