The Technology And Engineering Application Of Flare Gas Recovery For Natural Gas Treatment Plant

This article takes the third gas treatment plant as the research background,natural gas processing plant of flare gas recovery technology and engineering application have been studied in detail,broke the linde company the original design,the emptying torch gas recovery technology has been researched.The technology will be within three air vent pipe factory emptying torch gas by gas holder,compressor unit,such as facilities for recycling,at the same time ensure the safety of the device in a state of emergency and rapid emptying.The field application of this technology ultimately achieve the goal of the extinguished the torch,not only to improve the enterprise’s resource utilization,to achieve the clean production,and reduced emissions of greenhouse gases and waste gas,to protect the environment of the surrounding area.In this study,the emptying torch gas recovery technology including the torch of the source of the recycle gas and gas analysis,process route analysis and determination,determination of key equipment for recycling and determination of flare gas recovery security control system.Through the study,for the three gas plant,using two methods to indirect measurement of emptying torch gas flow rate,flame height,respectively,cumulative volume difference;Emptying torch gas recovery technology is mainly divided into storage pressure gas recovery process and direct suction compression recovery process,according to the actual situation of three gas plant,selects the gas holder storage pressure recovery process for flare gas recovery;Three gas factory emptying torch gas gas holder with rubber sealing dry gas holder,its nominal capacity is 2000 m3;Recycle compressor adopts wet screw compressor,and USES the frequency conversion motor recovery system run more smoothly;Considering emergency recovery system safe operation and the torch system security,facilities for emergency vent is designed for emergency vent valve,water facilities,pipeline rupture disc three pressure,in turn,increase the redundancy of Settings,including emergency vent valve use pneumatic fast ball.Flare gas recovery technology of field engineering application shows that the technology has solved the long caused by emptying torch burning waste of resources,greenhouse gases,thermal radiation,light pollution and greenhouse gas emissions and other environmental problems,to avoid the problem so caused by all kinds of relationship of workers and peasants,for the enterprise has played a positive role in implementing the "cleaner production".At the same time,the application of the results achieved to make full use of resources,has great popularization value,and provides experience for domestic similar equipment modification.
