我国加油站三次油气回收现状与技术展望

Status and technology prospects of tertiary oil vapor recovery of petrol station in China

结合近年国内环保趋势以及加油站相关环保政策,论证了三次油气回收的必要性,详述了国内加油站三次油气回收技术的应用进展和相关问题,提出:吸附与吸收技术相结合并应用新型吸附与膜材料将是未来的研究与应用方向;过程控制优化将保证处理装置长期稳定运行并进一步提升油气回收率。

Combined with the trend of domestic environmental protection in recent years and the relevant policies for environmental protection of petrol stations,the necessity of tertiary oil vapor recovery is demonstrated,and the application progress and related problems of tertiary oil vapor recovery technology in domestic petrol stations are described in detail.It is proposed that the combination of adsorption and absorption technology and the application of new adsorption and membrane materials will be the research and application directions in the future;process control optimization will ensure the long-term stable operation of the treatment device and further increase the recovery rate of oil vapor.
