医药化工的变压吸附(PSA)制氮技术探讨

Discussion on the Pressure Swing Absorption(PSA) Nitrogen Production Technology in Pharmaceutical Chemical Industry

在化工生产中,氮气属于惰性气体,化学性质较为稳定,不容易与其他物质发生反应,因此广泛用作保护气、密封气等。在医药生产中,氮气的使用较多,目前制氮技术主要有PSA变压吸附法、低温法、膜分离法,而应用最为广泛的一种制氮技术为PSA制氮技术。从医药化工的变压吸附(PSA)制氮技术,以及相关的内容进行了分析。

In chemical production, nitrogen is inert gas, relatively stable chemical properties; it is not easy to react with other substances, thus widely used as shielding gas, gas seal and etc. In pharmaceutical production, the use of nitrogen is more. At present the nitrogen production technologies mainly include pressure swing adsorption （PSA） method, low temperature method and membrane separation. Application of PSA is the widest. In this article, the pressure swing absorption （PSA） nitrogen production technology in pharmaceutical chemical industry was introduced.
