海上注碳平台CO2泄漏扩散及富集特性数值模拟研究
Numerical Simulation Study on CO2 Leakage,Diffusion and Enrichment Characteristics of Offshore Carbon Injection Platform
摘要
Abstract
To further investigate the leakage,diffusion,and enrichment of CO2 in offshore carbon injection platforms under different sea wind environments,Based on computational fluid dynamics and gas leakage and diffusion theory,Fluent software is used to simulate the CO2 leakage,diffusion,and enrichment process of offshore carbon injection platforms under different wind field conditions.The characteristics and influencing factors of gas leakage and diffusion process are analyzed,and the migration law of CO2 after leakage accidents,the distribution law of hazardous areas,and the change law of gas concentration at monitoring points were studied.The research results indicate that platform structure is the most important influencing factor for CO2 platform diffusion and enrichment,which significantly affects the airflow movement and deck distribution.Wind speed,wind direction,leakage rate,and leakage location are also the most important influencing factors for CO2 diffusion and enrichment on offshore carbon injection platforms.Wind speed,leakage rate,and enrichment degree are positively correlated,and adverse conditions of leakage location and wind direction can cause significant CO2 diffusion and enrichment.The concentration distribution of CO2 leakage accidents under different conditions is determined through leakage simulation methods,which provides support for the deployment plan of CO2 leakage monitoring points on offshore platforms,improves the safety andreliability of the platform,and promotes the green and low-carbon development of petroleum and petrochemical industry.关键词
