天然气门站压力能的回收利用

摘要

我国天然气大多采用高压输送至各大门站，经调压至中低压后进入下游燃气管网。天然气在调压的过程中具有丰富的压力能可供回收，利用各种压力能回收装置，可用于天然气发电、天然气液化调峰、天然气的净化处理、城市冷库的冷源、废旧橡胶的深冷粉碎和加压CNG等。%Natural gas is mostly conveyed with high pressure to gateway stations in China, at which it is regulated to medium and low pressure to be delivered to downstream gas pipeline networks. During the pressure regulation great amount of pressure energy is produced, which can be effectively recovered by recovery equipment to be used in electricity generating, peak shaving of natural gas liquefaction, natural gas purification, urban cold storage, cryogenic grinding of waste rubber and CNG processing, etc.
