Amount of Hydrogen Sulfide in Natural Gas
On the content of hydrogen sulfide in natural gas
Between heaven and earth, there are many types of gas, and natural gas is responsible for people's livelihood and national use. Among them, the content of hydrogen sulfide is related to a wide range and cannot be ignored.
To know the amount of hydrogen sulfide in natural gas, the first thing to do is to understand its detection method. In the past, it was mostly based on the reaction of chemical reagents to observe the change of color and the generation of precipitation to measure the amount of hydrogen sulfide. However, although this method has traces to follow, there are no errors. Today, with the development of science and technology, the method of instrument detection is gradually emerging. The instrument of gas chromatography can accurately obtain the composition of gas analysis and the amount of hydrogen sulfide in an instant. The reason is that different gases behave differently in the chromatographic column, and the time of retention is different. According to this, they can be distinguished and measured.
The content of hydrogen sulfide in natural gas has a huge impact. If the content is small, it will not be a big obstacle to pipeline transportation, but if it gradually accumulates, its harm will become apparent. Pipeline materials are mostly metals. Hydrogen sulfide can be produced in an acidic environment when exposed to water, and metals are prone to corrosion. At first, the surface is mottled, and then there are many holes, and the strength of the pipeline gradually disappears. If it is serious, or there is a risk of leakage, the gas will overflow, and it will ignite in case of open fire, or even explode, endangering the surrounding life and property, which is not a big disaster.
Furthermore, if natural gas is used in chemical production, the content of hydrogen sulfide also needs to be strictly controlled. Many chemical reactions have high requirements on the purity of raw materials. Hydrogen sulfide exists in it, or causes catalyst poisoning, and the activity is sharply reduced. The speed of the reaction and the quality of the product are all affected by it. In the chemical industry, precision is the key, and the slightest mistake may lead to the loss of the whole game.
As for the specification of its content, each place should make it according to its own situation. For civilian gas, in order to ensure the safety of the people, the content of hydrogen sulfide must be limited to a strict limit. Although it may be different for industrial use, it should not be done arbitrarily. All because of the application of natural gas, it is related to the safety of the society and the stability of people's livelihood.
To reduce the amount of hydrogen sulfide in natural gas, there are also various good strategies. Absorption method, with a specific solution, hydrogen sulfide is added to it, so that the gas and liquid are in contact, the hydrogen sulfide remains in the liquid, and the natural gas can be purified. Adsorption technology, with porous materials, such as activated carbon, with its strong adsorption power, hydrogen sulfide is captured into the invisible.
All in all, the content of hydrogen sulfide in natural gas, like the weight of the scale, weighs safety and efficiency. In order to make the best use of natural gas, the strict prevention and control, and the good governance, it takes a lot of effort to make the best use of natural gas, benefit the people, and help the prosperity of the country.
