Sulfur element analysis auxiliary treatment device and method for eliminating influence of high content nitrogen element

Abstract

The invention provides a sulfur elements analysis auxiliary treatment device and a method for eliminating influences of high content nitrogen elements. The device comprises a three-way reaction tube.A first inlet of the three-way reaction tube is connected with an ozone supply source. A sample gas inlet pipeline is connected with a second inlet of the three-way reaction tube, and is used for accessing sample gas subjected to high temperature catalytic oxidation. An outlet of the three-way reaction tube is connected with a sample gas outlet pipeline, and is used for feeding the sample gas intoa sulfur element detection device. The ozone entering the three-way reaction tube from the first inlet can react with the sample gas entering the three-way reaction tube from the second inlet, and the reacted sample gas enters a sulfur element detection link through the outlet of the three-way reaction tube, so that influences on the detection result of the nitrogen elements can be eliminated.

Description

technical field [0001] The invention relates to a pre-processing device and method of a sulfur element analyzer realized by the principle of ultraviolet fluorescence method, which can eliminate the analysis result of high-concentration nitrogen element on the content of sulfur element in a sample. Background technique [0002] There are many methods for the analysis of sulfur in products in the petrochemical industry, the main ones are: GB / T 380-1977 (2004) "Determination of Sulfur Content in Petroleum Products (Lamp Method)", GB / T 387-1990 "Dark Color Determination of Sulfur Content in Petroleum Products (Tube Furnace Method)", GB / T 388-1964 "Determination of Sulfur Content in Petroleum Products (Oxygen Bomb Method)", SH / T 0689-2000 "Light Hydrocarbons and Engine Fuels and Other Oils Determination of Total Sulfur Content in Petroleum Products (Ultraviolet Fluorescence Method)", GB / T 11140-2008 "Determination of Sulfur Content in Petroleum Products by Single Wavelength Dispe...

Problems solved by technology

This will seriously affect the final result of sulfur element analysis, and the measured value will be significantly higher

[0005] If a complex sample chemical pretreatment method is used, on the one hand, the operation requirements are high and the process is complicated; on the other hand, the sulfur element to be measured will be affected and lost during sample processing, and accurate measurement results cannot be obtained in the end.
