海上油气生产平台硫化氢气体扩散

为评估高含硫化氢气体海上油气生产平台硫化氢泄漏风险，对硫化氢气体泄漏后质量浓度分布进行模拟计算，以指导硫化氢气体泄漏后果评估和个人防护装备的配置。在分析气体扩散分析理论公式的基础上，对海上油气生产平台硫化氢气体扩散模拟分析的场景选择、感受点选取、硫化氢气体的破坏标准和模拟结果的应用等硫化氢气体扩散的各重要影响因素进行讨论，并结合实际工程实例对工程实践中各影响因素的选择和考量进行讨论。

Hydrogen Sulfide Gas Dispersion from Offshore Oil and Gas Production Platform

In order to evaluate the risk of H2S gas leakage from offshore oil and gas production platform with high H2S mass concentration, the mass concentration distribution after H2S gas leakage is simulated and calculated to guide the consequence assessment of H2S gas leakage and the configuration of personal protective equipment. Based on the analysis of the theoretic method of gas dispersion calculation, some facts affecting H2S gas dispersion are discussed, including the scene selection, sensing point selection, damage standard of H2S gas and simulation result application. Combined with the actual engineering case, the selection and consideration of the influencing factors in the engineering practice are discussed.
