摘要:
为了预测含硫天然气泄漏后危险气体的扩散距离和危险区域的面积,以中国石油长庆油田第五采气厂输送管线为例,结合当地的实际环境,根据高斯烟羽模型选择适合于含硫天然气连续泄漏的控制参数,开展了含硫天然气在不同泄漏量、大气环境、地面粗糙度条件下连续泄漏的数值模拟研究,得出了相应的下风向扩散距离及其危害面积。结果表明:不同的条件下,天然气扩散的距离和面积不同。泄漏量越大,天然气扩散的距离和危害面积也越大,H2S的危险区域的面积也越大; 大气稳定性越高,扩散距离和危害面积越大; 地面粗糙度越大,扩散距离和危害面积越小。模拟结果可为人员疏散方案及应急救援预案制定提供理论依据和技术指导。
Abstract:
In order to predict the diffusion distance and hazard area of sulfur natural gas leakage diffusion,taking China Petroleum Changqing Oilfield fifth gas field gas pipeline as an example and combining the actual local conditions,according to the Gaussian plume model,we select suitable control parameters for a continuous leak of sulfur gas.Research on numerical simulation of continuous leak of sulfur natural gas on the different leakage,atmosphere and surface roughness conditions,and obtain the diffusion distance and hazard area in correspnding down wind direction.Results show that under different conditions,the distance and area of the natural gas diffusion are different.Hazard area of natural gas and H2S increases with increase of the leakage,the greater the stability of the atmosphere,the greater the diffusion dtistance and the hazard area will be,but the diffusion distance and hazard area tend to decrease with increase of the surface roughness.The simulation results can provide theoretical basis and technical guidance for formulation of the evacuation plan and emergency rescue plan.
