Determination of hydrogen sulfide content in fuel oils
Rapid liquid phase extraction
Warning --- personnel using this standard should have formal laboratory work experience. The use of this standard may involve some danger
Materials, equipment and operations, this standard does not indicate all possible safety issues. It is the user's responsibility to take appropriate safety and health measures
Shi, and ensure compliance with the conditions of the relevant state laws and regulations.
1 Scope
This standard specifies the rapid liquid phase extraction method for the determination of hydrogen sulfide fuel oil in the liquid content of the method.
This standard applies to the 50 ℃ kinematic viscosity of not more than 3000mm2/s of fuel oil, including marine residual fuel, distillate fuel and oil
Determination of liquid phase hydrogen sulfide in blending component oil. This standard includes Method A and Method B two test steps.
Note 1. This standard also applies to the determination of 50 ℃ kinematic viscosity higher than 3000mm2/s samples (see 7.2), but the precision will be affected.
Note 2. Some samples that contain thiol or alkyl sulfide disrupters at levels greater than 5 mg per kilogram (mg/kg), as measured by Method B, will yield
Higher hydrogen sulfide content, Method A can be used to eliminate this effect.
Note 3. If the sample contains fatty acid methyl esters, the determination of hydrogen sulfide content has no effect.
Warning --- Hydrogen sulfide is a very dangerous, toxic, explosive, colorless and transparent gas that can be found in crude oil. Hydrogen sulfide can also be refined
Fuel oil refinery plant formed during the process, and oil handling, storage and distribution in the release. Low concentrations of hydrogen sulfide gas smell of rotten eggs
Road; high concentrations of hydrogen sulfide can cause loss of taste, headache, dizziness, higher concentrations will be fatal. Hydrogen sulfide is strongly recommended
Should be aware of the hazards of hydrogen sulfide gas and be able to take appropriate steps to prevent exposure to toxic gases.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version applies to this article
Pieces. For undated references, the latest edition (including all amendments) applies to this document.

3 Method summary
A sample of known mass is injected into the heated test tube containing the diluted base oil. Bubbling the air into the sample fluid, which was extracted
Hydrogen sulfide gas. The blown hydrogen sulfide, along with the air, enters the detector through a filter box (Method A only) cooled to -20 ° C,
The hydrogen sulfide content in the air was measured to calculate the hydrogen sulfide content in the sample liquid phase. In method B, the cryogenic filtration is omitted
Box related steps.
4 equipment
4.1 hydrogen sulfide determination instrument see Appendix A. Method A instruments include a gas phase processor, method B does not contain a gas phase processor.
4.2 Analysis Balance. Single or double plate, a sense of the amount of 0.001g.
4.3 Syringe or burette. 20 mL for injection of diluent oil (5.1) with ± 1% accuracy.
4.4 pipette capacity of 1mL, used to join the sample. The accuracy should not exceed the error of 1000 mL as instructed by the instrument manufacturer
± 0.25%, coefficient of variation of 0.04%. In order to optimize the operation of the system, it is recommended to use the manufacturer's model pipette.
