Embodiment 2

[0039] Embodiment 2: Measuring the total amount of sulfide in a natural gas sample

[0040] Using the device of Example 1, the detection method for detecting the total amount of sulfide in natural gas includes 3 steps.

[0041] 1. Sampling

[0042] The sampling port of the gas delivery pipeline is connected to the sampling point of the natural gas sample, the valve of the sampling cylinder is opened to deflate, the pipeline valve 1 and the rotameter 2 are opened to adjust to the ideal flow rate, and the natural gas enters the gas delivery pipeline; The intake flow rate of natural gas samples is 300-350mL / min;

[0043] 2. Hydrolysis reaction

[0044] After the natural gas sample passes through the water vapor saturator, a hydrolysis reaction occurs in the hydrolysis reactor to produce a hydrolyzed natural gas sample, and the hydrolysis reaction hydrolyzes the sulfide to generate hydrogen sulfide gas and carbon dioxide gas. The catalyst provided in the hydrolysis reactor is a...

Abstract

The invention relates to a detecting device for total sulfur content in natural gas and a detecting method thereof. The detecting device comprises a gas delivering pipeline, a pipeline valve, a vaporsaturator, a hydrolysis reactor and a hydrogen sulfide measuring device, wherein the pipeline valve, the vapor saturator, the hydrolysis reactor and the hydrogen sulfide measuring device are sequentially arranged on the gas delivering pipeline, the pipeline valve is connected with a gas inlet of the gas delivering pipeline, a gas outlet is formed in the hydrogen sulfide measuring device, the hydrolysis reactor is filled with an organic sulfur hydrolyzing catalyst, and the hydrolysis reactor is connected with a heater. By the aid of the detecting device, sulfide in the natural gas can be hydrolyzed into hydrogen sulfide, then the total hydrogen sulfide content in a composite sample can be measured by the hydrogen sulfide measuring device, and the total sulfur content in an original naturalgas sample can be obtained by calculation. The detecting device is simple in structure, simple and safer to operate, low in cost and high in precision, overcomes the deficiency that the semiconductorlaser absorption spectrum technology cannot be used for online measurement of the total sulfur content in the natural gas and provides a novel effective measurement means for the total sulfur contentin the natural gas, and the detecting method is mild in condition.

Description

technical field [0001] The invention relates to the technical field of detection methods for impurities in natural gas, in particular to a device for detecting total sulfur content in natural gas and a detection method thereof. Background technique [0002] As a clean energy, the popularization and use of natural gas can greatly alleviate the pressure of the current aggravation of air pollution. At present, the use of natural gas in my country has become quite common. At the same time, the advantages of natural gas itself make its use widely recognized by the public. . However, there are still some problems in the use of natural gas in actual life, the most important of which is that the detection technology of the sulfur content of natural gas needs to be further strengthened, and the sulfur content in natural gas will also pollute the atmospheric environment during the combustion process. Therefore, the improvement of detection technology for sulfur content in natural gas ...
