成品油管道泄漏扩散规律分析

对成品油管道泄漏扩散过程进行了研究,建立了油品孔口出流模型、油品喷射模型、油品蒸发模型、油池扩散模型和油品渗透模型等适用于油品泄漏过程不同阶段的理论分析模型.基于这些分析模型,可以精确地评价一起可能发生的泄漏事故对公众和环境造成危害的严重程度,以便于更加准确、切合实际地对成品油管道泄漏事故进行定量风险评价,为制定管道事故应急预案,减少事故损失提供理论指导,同时也有助于对成品油管道进行完整性管理研究.

The Study on Oil-diffusing Law of Product Pipeline Leaking

The study on oil-diffusing law of product pipeline leaking is a key technical issue for the risk assessment of product pipeline. The authors study the diffusing process of the product pipeline leaking and establish the theoretical analysis models for the different phases of the oil diffusing,including the model of oil product streaming from orifice, the model of oil product jetting,the model of oil product evaporating,the model of oil sump enlarging, the model of oil product infiltrating. On top of these models, the degree of hazardous to public and environment should be precisely evaluated if the product pipeline is leaked. Therefore, the risk of the product pipeline leaking should be quantified more accuracy and accord with the fact,which is helpful to reduce the loss in a pipeline accident and study on the integrity management of product pipeline.
