液化天然气气化站风险评价实例分析

摘要

以某拟建液化天然气气化站项目为例,对环境风险评价的要点进行了分析.根据风险导则要求及重大危险源辨识标准,对液化天然气气化站的重大风险源进行了识别,给出了最大可信事故及源强的确定方法,采用多烟团模式及蒸气云爆炸模式对确定的最大可信事故后果进行预测,并阐述了风险计算和评价结论及风险管理等内容.%The essentials of ERA were analyzed with example of LNG vaporizing station project. According to the requirement of risk guideline and significant dangerous source identification standard, the significant dangerous source of LNG vaporizing station was identified. The determination method of the most greatly credible accident and the source intensity was put forward. The aftereffect of the most greatly credible accident was predict, which was determined by INPUFF and the fume cloud explosion modes. Risk computation, appraisal conclusion and risk management were discussed.
