摘要:: 为了保障CO2 的输送安全，从CO2 泄漏扩散的后果出发，考虑CO2 泄漏扩散时的相态变化及重力的影响，利用PHAST 软件建立CO2 管道的泄漏扩散模型，以最不利工况作为初始条件，计算假定不同阀间距下的SLOD（致死率等于50％）影响范围，从而确定CO2 管道不同等级地区下的阀间距。结果表明：一级地区从安全考虑并不需要建设阀室，但是为了方便管道维修，可以在便于维修的部位建立阀室；二级地区可以根据相应的户数选择合适的阀间距，但最大不超过60 km；三、四级地区不推荐超临界CO2 管道输送。基于泄漏扩散后果评价的CO2 管道阀间距研究为中国CO2 管道输送相关规范的制定以及对CO2 管道进行安全评价和事故后果分析提供了一定的理论支持。
