Study on combustible gas leakageage and diffusion by CFD simulation

Liu Xin (BV-BOSUN(Tianjin)Safety Technology Co.Ltd,Tianjin,300201,China)  
The marine petroleum exploitation is a high-risk industry,particularly at the high-pressure natural gas extraction section,where there are a great number of static sealing points,so combustible gas leakageage can very likely occur.Computational Fluid Dynamics(CFD) can accurately analyze,fix and predict the affected region of the combustible gas leakageage,which is instructive to accident prevention and control,platform emergency and evacuation mechanism,etc.In this paper,on the basis of prophase investigation and in-depth analysis, according to the actual operation status of equipment,the main leakageage points on the platform were selected.Using computational fluid dynamics simulation,building the reasonable physical model,selecting the appropriate diffusion equation and the boundary condition,CFD simulate of gas leakageage on the platforms was carried out.It is shown from the calculated results that the contact tower and the testing separator of the platform are most inclined to leakageage gas,so it is recommended to enhance the daily maintenance of the pipelines,valves and flanges in the above units to prevent and control accidents.The contact tower,production separator and gas pigging launcher of the center platform,gas well Christmas tree,testing manifold and testing separator of the wellhead platform have higher operation pressure with more serious consequences and larger range of influence after the leakageage and diffusion,so it is recommended to do inspection on the above key equipments based on risk analysis.The firewall,control room and other rooms will,to a certain extent,affect the ventilation in the deck space, and there will be a larger range of influence after the gas leakageage when the wind is on the windward side of the above barriers.At this point, it is recommended to strictly control the ignition sources over the whole region of influence.The danger zone and fire zone of the platforms can be effectively divided with the help of the calculated CFD results,which provide reference for the refinement of the emergency program,the post-accident emergency command and the selection of correct escape routes.
