What methods are used for analyzing the sulfur content in crude oil in petrochemical enterprises?
Thread Content
Let’s discuss what methods are used for analyzing the sulfur content in crude oil in petrochemical enterprises. Which method is the best?
The Coulomb method is commonly used. The method is on pages 204–212 of the first volume of \"Crude Oil Analyst\".
Is there space for “Crude Oil Analyst”?
Can’t the Coulomb method sh/t0253 be used to analyze only light oil?

GB/T17606 \"Determination of sulfur content in crude oil – Energy-dispersive X-ray fluorescence spectrometry\" can also be used.
We use both the Coulomb method and X-ray fluorescence method (GBT17040)
What reference standard is used in the Coulomb method? How to inject the sample? Is the Coulomb method accurate? When I do Coulomb, the conversion rate varies greatly each time
1. Taking into account the views of various parties, where feasible, a Coulomb sulfur analyzer can be used; the impact of conversion rates can be corrected using standard samples. However, the conversion rates vary for different substances, and this is precisely the drawback of using a Coulomb sulfur analyzer. 2. If possible, gas chromatography equipped with an FPD can be used for analysis. This topic has been discussed before; it is recommended that the original poster look into it
