Progress on gathering and treatment technologies of high-sulfur natural gas in China

With the large-scale development of high-sulfur gas reservoirs in China, the matching gathering and treatment technologies of high-sulfur natural gas are being updated constantly. Herein, the development situation of high-sulfur natural gas reservoirs in China was briefly introduced, the gathering technology, purification mode, desulfurization technology and sulfur recovery technology of high-sulfur natural gas were systematically summarized, and a series of complete, advanced and feasible achievements in safety control, sewage reuse, management mode and "five-oriented"construction of high-sulfur gas fields were expounded in details. In the future, scientific and technological research, as well as development of key technologies, should be conducted continuously in desulfurization and treatment of sulfur-containing tail gas, so as to constantly pursue low-carbon environmental protection and realize "five-oriented"construction, further striving to build a high-quality and standardized development and construction mode for high-sulfur gas fields.
