天然气净化厂余压发电项目温室气体减排潜力研究

Study on the potential of greenhouse gas emission reduction of natural gas purification plant residual pressure power generation project

摘要

摘要:
目的以西南油气田公司天然气净化总厂引进分厂的天然气余压发电项目为例，分析了天然气余压发电项目减少温室气体排放的潜力。
方法利用温室气体国家核证自愿减排量(CCER)方法学CMS-025-V01废能(废气/废热/废压)回收利用，分析天然气余压发电不同工况下的温室气体排放量。
结果利用天然气余压发电，预计最高每年发电量为418.73×10⁴ kW·h，最高每年温室气体减排量为2 393 t。
结论天然气净化厂余压发电项目既能对净化厂生产提供电力供应，又能减少能源消耗和温室气体排放。

Abstract:
Objective The potential of greenhouse gas emission reduction is analyzed for the natural gas residual pressure power generation project of the natural gas purification plant of PetroChina Southwest Oil & Gasfield Company.
Methods The greenhouse gas emission is analyzed for the natural gas residual pressure power generation in different work conditions by using CMS-025-V01 waste energy recycling (waste gas/waste heat/waste pressure), which is one of Chinese certified emission reduction(CCER) methodology.
Results Based on natural gas residual pressure power generation, the maximum annual power generation is expected to be 4.187 3 million kW·h and the maximum annual greenhouse gas emission reduction is 2 393 t.
Conclusions The natural gas purification plant residual pressure power generation project can not only provide power supply for the purification plant, but also reduce energy consumption and greenhouse gas emissions.
