Comparative analysis of domestic and foreign liquid ammonia pipeline transportation technical standards
摘要
Abstract
Pipeline transportation is the most economical long-distance transportation method for liquid ammonia,and the standardization of liquid ammonia pipeline transportation technology is an important link to ensure the standardized construction,operation and maintenance of pipelines.However,there is relatively little information on liquid ammonia pipeline transportation technology in the current domestic standards.For this purpose,a systematic analysis was conducted on the current status of liquid ammonia pipeline construction at home and abroad,as well as the current technical standards for liquid ammonia pipeline transportation.The focus was on exploring the similarities and differences in the provisions of transportation processes,pipeline routes,pipeline(pipeline accessories,supports)design and ammonia transportation stations in relevant standards,and providing applicability suggestions.For the quality requirements,medium flow rate,pipe material selection,corrosion allowance and station protection facilities of liquid ammonia pipelines,reference can be made to standards such as GB/T 536,GB 50253,SY/T 7629,SH/T 3074 and ASME B31.4(the United States),respectively.For the buried pipeline clearance of the liquid ammonia pipeline,regional classification,maximum spacing of isolation valve chambers,fire protection spacing at stations and safety relief,relatively strict standards and regulations related to oil and gas pipelines(GB 51142,GB50253,GB50160,and 29 CFR1910.11(the United States))can be referred to for implementation.Considering the differences in the toxic properties,diffusion characteristics and prevention and control measures between liquid ammonia and oil and gas,it is recommended to conduct risk assessment and prediction research on the diffusion and safe release of liquid ammonia leakage,and further demonstrate the spacing values and regulations applicable to liquid ammonia scenarios.关键词
