Natural gas odorant methyl acrylate gas chromatograph

Gas odor is one of the active safety measures taken by gas companies, and has received great attention. At present, the commonly used odorants in China are tetrahydrothiophene (THT) and thiol mixture (TBM). Both of these odorants contain sulfur (S) element, which will generate S02 gas during combustion, affecting the quality of gas combustion. The product quality of some industrial users also affects and pollutes the environment. As people's requirements for clean energy continue to increase, and the control of sulfur content in natural gas is constantly strengthened, the use of sulfur-free odorants has become a future development trend.
The sulfur-free odorant has the same function as the conventional odorant, it is a substance that can play a warning role, has strong mixing ability with natural gas, is gaseous in the gas pipeline, non-corrosive, and will not affect the human body and the environment when burning. Harmful.
Sulfur-free odorant is a colorless and transparent liquid with a strong pungent odor. It is composed of C4H6O2 (methyl acrylate), C5H8O2 (ethyl acrylate), C7H10N2 (3-ethyl-2 methylpyrazine), and C15H240 (2, 6-di-tert-butyl-p-methylphenol), the mass fraction of each component is 37.4%, 60.0%, 2.5% and 0.1%, respectively. The relative molecular mass of the sulfur-free odorant is 95.543, the boiling point at atmospheric pressure is 80 ° C, the melting point is -80 ° C, the spontaneous combustion temperature is 395 ° C, the explosion limit is 1.6% to 23.0%, it is insoluble in water and soluble in ethanol. The sulfur-free odorant does not contain sulfur, and the combustion products have no pollution to the environment.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. advances with the times and is guided by scientific development. Under the leadership of Manager Wang Xiaoying, relying on Xiangying Analytical Technology, Chromatographic Engineering Research Institute, Analysis and Test Center, 3 research units, research and development The Natural Gas Deodorant Methyl Acrylate Gas Chromatograph was published. The methyl acrylate and ethyl acrylate odorants in natural gas were successfully measured with satisfactory results.
