谢谢啊 啊

不错的图纸 我要好好研究研究

图纸中采用的冷水机组是螺杆式的吗？国内哪家的设备好用，价格合理？

现在好象大多使用螺杆机组，可是我看资料好事是离心机组的性能系数高一些啊，难道离心机组除了价钱高以外还有别的什么缺陷吗？？？？？

Cryogenic distillation of air has been widely used for air
separation over the last 80 years. Since the advent of synthetic
zeolites in 1950s and pressure swing Adsorption (PSA)
processes in 1970s the small and medium scale air separations
are being increasinglyaccomplished byadsorption.
PSA air separation has become more economical at product
throughputs below 10,000 standard cubic meters per hour
compared to cryogenic distillation (Agrawal, 2001). Now,
about one-fifth of air separation is carried out using adsorption
technologies, i.e., PSA and vacuum swing adsorption
(VSA) (Rege and Yang, 1997).

大冷量用离心机组!!!

还是离心机啊.呵呵...

楼主的图对我有启发

谢了啊,不错
