天然气高压管网余压发电项目可行性分析

Analysis of Feasibility of Power Generation by Using Residual Pressure in High Pressure Natural Gas Pipeline Network

城市天然气高压管网蕴含了巨大的压力能。该文通过对天然气输配系统的工艺分析,探讨了输配过程中压力能损失的回收方式及应用方向。提出了利用高压调压站的压力差通过透平膨胀机(TRT)发电的天然气高压管网余压发电方案。粗略估算了发电潜力及通过发电创造的经济效益和社会效益。

The recycle and application of pressure energy lost in the course of natural gas transmission and distribution discussed,the paper proposes to generate electricity by using residual pressure in high pressure natural gas pipeline network—by means of pressure difference from high-pressure regulator station through turbineunit(TRT).The power generation potential and economic and social benefits obtained from power generation are also estimated roughly.
