摘要
随着输气管道的不断建设,输气站的放空气量不断增加,造成较严重的资源浪费和环境污染。结合输气站工艺流程,根据计划性放空气量大、次数多、时间约束小等特点,提出了以地下储气井储气技术为核心的输气站放空气回收工艺,在输气站中选取合适位置建造储气井,利用气体自身的压力将高压放空气体引至低压储气井中储存回收。储气井回收输气站放空气的主要设施包括2口储气井以及相关管道和阀门。在中国石化某输气站进行实例应用,结果表明:该方式具有安全性高、占地面积小、设备布局美观、经济性良好等优点,能够避免资源浪费,达到节能减排的目的,值得进一步研究和推广。(图2,表2,参12)。
With the continuous construction of gas pipeline, the volume of vent gas from gas compressor station is increasing, which leads to serious waste of resources and environment pollution. Combining with the technical process of gas compressor station and taking into account the characteristics such as large volume and multiple times of planned gas venting and low limitation of time, this paper proposes a vent gas recovery process from gas compressor station with underground gas storage well as a core. Gas storage wells should be built at proper positions in the gas compressor station. And based on the characteristic of gas flowing from high pressure to low pressure, the gas pressure itself can lead the high-pressure vent gas to the low-pressure gas storage well for storage and recovery. The main facilities in the gas recovery station include two gas storage wells and other related pipes and valves. The application of this technology in a gas compressor station shows that this method has advantages such as high safety, small floor area, reasonable layout of equipment and high economic profit, which can avoid the waste of resources and save energy and reduce emission at the same time, and therefore is worthy of further research and popularization. （2 Figures, 2 Tables, 12 References）
