摘要
含硫天然气泄漏后,H2S扩散容易造成严重的中毒事故,是含硫天然气设备安全运行的重大隐患之一。介绍重气扩散模型的研究现状,对比分析各类模型的基本原理、适用范围和优缺点。结合具体场景,分别运用高斯烟羽模型、UDM模型、CFD模型对含硫天然气的泄漏扩散规律进行模拟,并分析各模型的精确度和适用性。
H2S diffusion is liable to cause serious poisoning accidents after the leakage of natural gas with sulfur,which is one of the major hidden dangers for the safe operation of natural gas with sulfur. The research status of heavy gas diffusion models is summarized in this paper,to compare and analyze the basic principles,application scope,advantages and disadvantages of various models. Gaussian plume model,UDM model and CFD model are used to simulate the leakage and diffusion of natural gas with sulfur in specific scenarios,to further analyze their accuracy and applicability.
