The task of the natural gasification plant is to treat the natural gas containing impurities such as sulfide oxide, magnetic dioxide, organic sulfide, etc., so that it meets the natural gas product standards. Natural gas is an industrial energy, chemical raw material and civilian fuel, etc., and covers a wide range of areas. Standardize natural gas! Safety management is extremely necessary. For this reason, this standard is specially formulated. This standard is proposed and coordinated by the Petroleum Industry Safety Professional Standardization Technical Committee. The originating units of this standard are: Refining and Chemical Division, Technical Safety Division, and Technical Supervision Division of Sichuan Petroleum Pipeline Bureau. The main drafters of this standard are Zhang Jieshan, Chen Ming, Wang Zhengping, Du Shunyou, Chen Shengyong, Zhang Bolin, and Liu Xiao. Scope
Petroleum and Natural Gas Industry Standard of the People's Republic of China Safety Specification for Natural Gas Purification Plants
Safety rude for natural gas conditioning plantsSY 62781997
This standard specifies the overall requirements for the design, commissioning, production, and equipment maintenance of natural gas purification plants. This standard is applicable to petroleum enterprises with a natural gas processing capacity of 50×10m/d and above. Natural gasification stations with relatively small treatment capacity can also refer to it for implementation.
