上海利用天然气压力能的可行性分析

Feasibility of Recovering Energy from High-pressure Gas Networks in Shanghai

天然气输配系统中普遍采用高压输气、中低压配气方式,调压器节流降压过程损失了大量压力能。本文综述了高压天然气的压力能利用方式和局限,并就上海的管网运行压力级制,提出了可能的利用方法以及实施这一技术需解决的问题。

High-pressure transmission and medium/low-pressure distribution have been widely adopted in natural gas transmission and distribution systems. Exergy in high-pressure natural gas have been wasted in throttling process of pressure regulators. In this paper some technical measures to make use of exergy of high-pressure were reviewed, in the light of theoretical analysis and practical procedures. A feasible approach for Shanghai natural gas networks was put forward, and related problems to be solved in advance was also explored.
