摘　　要：以某拟建的渣油催化裂解制丙烯等化工原料项目为例,对石化项目环境风险评价的要点进行了分析,对项目的重大风险源进行了识别,并给出了最大可信事故及源强的确定方法,分别采用世界银行推荐的TNO气团爆炸公式及非正常状态下的面源模式对确定的最大可信事故后果进行预测,给出了风险计算和评价风险管理的结果。A complete environment risk assessment （ERA） of petrochemical project generally consists of project outline, environment risk identification, accident source term analysis, consequence calculation, risk computation and assessment, risk management and so on. In this paper, the essentials of ERA on the petrochemical proiect are studied based on a proposed petrochemical project which will produce propylene by residue catalytic pyrolysis, including the recognition of the significant risk source for the project, the method determination of the maximum credible accident and source strength, and the consequence prediction for the definite maximum credible accident by taking the TNO air mass detonation formula and the surface source pattern under abnormal conditions recommended by the World Bank to give the results of risk calculation, evaluation and management.
