煤化工项目二氧化碳排放对局部大气环境的影响分析

摘要

To predict the long-term average volume fraction of C02 and 02 in the atmosphere of coal chemical industry park by box- type atmospheric environment model. After the implementation of the planning project, the results showed that compared with environmental background values, long-term average volume fraction of CO2 increased by 106.5% and O2 lowered 0.06%. During the constructions of coal chemical project, the impact of increasing CO2 concentration in the atmospheric environment on the safe operation of the air separation unit should be fully considered.%采用箱式大气环境模型预测了某煤化工园区大气中CO2、O2的长期平均体积分数。结果表明，规划项目实施后CO2的长期平均体积分数较环境背景值增加106．5％；O2的长期平均体积分数较环境背景值降低0．06％。煤化工项目建设时，应充分考虑大气环境中CO2浓度升高对空分装置安全运行带来的影响。
