常温空分氧氮一体化联合分离系统

Design of Combined Air Separation System for Oxygen-Nitrogen at Normal Temperature

总结了目前船用分立制氧、制氮系统和氧、氮提纯系统的不足之处,得出开发常温空分氧氮一体化联合分离系统的必要性。在此基础上,探讨了常温空分氧氮一体化联合分离系统的总体设计,构建了一种基于常温空分的联合制氧、制氮的创新系统方案,即以变压吸附技术与膜分离技术耦合的工艺技术对空气组分进行分离,仅以空气为原料,无需任何辅料,在仅消耗电力资源的情况下同时获取氧气和氮气。最后指出了常温空分氧氮一体化联合分离系统的发展趋势和应用范围。

Current independent marine separators for individual oxygen nitrogen generation along with purification system has many drawbacks,it necessitates the development of combined air separation system for oxygen-nitrogen.This paper gives a concept of overall design of such combined system at normal temperature condition.A novel scheme of combined solution for generating oxygen and nitrogen is presented.This design incorporates PSA-membrane separation technique,raw material used for separation process is air,consuming electric power and dispensing with any accessories.The paper also presents trends for the development of combined air separation system at normal temperature and indicates a range of applications possible in the future ship design.
