摘要
液化天然气(LNG)是我国天然气工业中的一大支柱产业,是环境影响评价工作中的重要项目类型之一,该类型项目对环境产生影响的主要是天然气液化过程中产生的废水、废气和环境风险。在分析LNG建设项目生产工艺流程的基础上,进行了详细的工程分析,找出了生产过程中的主要产污环节,确定了各环节的排污类型,并分析了项目所采取的环保措施的可行性以及污染物排放达标情况等问题。总结了LNG建设环境影响评价工作中工程分析的要点和环境影响分析,对LNG企业的环境保护和LNG建设项目的环境影响评价有一定的借鉴作用。
Liquefied natural gas(LNG)project is a major industry of natural gas industry in China. It is also one of the important project types of environmental impact assessment (EIA). The major impacts of LNG project on environment are wastewater, waste gas and environmental risk from natural gas liquefaction. Based on the analysis of LNG production process, detailed en- gineering analysis was carried out and main pollution emission links were found out. The feasibil- ity of environmental protection measures taken by the proiect as well as the achievement of the pollution control measures were discussed. The main ideas of the engineering analysis and envi- ronmental impact analysis in environmental assessment of LNG project were summarized, which has an important significance to the reserve increase of the mine.
