With the development of our society, we advocate clean energy, so the demand for natural gas as a clean energy is also increasing. However, in the process of natural gas exploitation, many gas wells often contain hydrogen sulfide, which will cause corrosion of equipment and pipelines, pollute the environment and endanger human health. With the development of science and technology, The wide use of natural gas desulfurization technology has solved these problems, but at the same time, the cost of natural gas purification and treatment has increased accordingly.
