Main points and methods of engineering analysis in environmental impact assessment of LNG project

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 engineering analysis was carried out and main pollution emission links were found out. The feasibility of environmental protection measures taken by the project as well as the achievement of the pollution control measures were discussed. The main ideas of the engineering analysis and environmental impact analysis in environmental assessment of LNG project were summarized, which has an important significance to the reserve increase of the mine.
