天然气加臭剂加注技术现状及展望
Status and prospect of natural gas odorant injection technologies
摘要
Abstract
Natural gas,with colorless,odorless,flammable and explosive properties,can be hardly detected in time in the case of leakage,which seriously threatens the safe operation of gas pipeline systems.The odorant injection technology serves as the core link to ensure safe transportation and distribution by imparting a warning odor to natural gas.In this paper,the development status of city gas odorant injection technologies is systematically reviewed,the principles,characteristics and applications of emerging natural gas odorant injection technologies are mainly analyzed,and the development direction of natural gas odorization technologies are predicted.The following results are obtained.First,due to outdated injection methods,the existing natural gas odorant injection technology is prone to result in substandard end concentration of gas odorant.Second,the new natural gas odorant injection technology ensures easy mixing of odorant with gas by optimizing the odorant injection method of the existing natural gas odorant injection method.Third,with the development of technologies such as Internet of Things,big data and artificial intelligence,the new natural gas odorant injection technology can ensure that the effect of natural gas odorization meets the standard.In conclusion,the future natural gas odorant injection technology will develop towards precision,automation and environmental protection,and will be deeply integrated with emerging technologies such as automatic control,Internet of Things,big data and artificial intelligence,to provide a strong support for the high-quality development of the natural gas industry.Moreover,relevant enterprises should comprehensively weigh the technical characteristics and select appropriate solutions,and research institutions should strengthen research & development and forward-looking layout,and promote innovative breakthroughs and industrial applications of natural gas odorant injection technologies,so as to ensure the safe and efficient operation of urban gas systems.关键词
