Cheaper, More Efficient Oxygen Through Novel Production Method

View PDF Document Text Only Version

The ability to separate oxygen from air has proven invaluable to many industries, because using pure oxygen in high-temperature furnaces improves their efficiency and reduces emissions. Although the benefits of using oxygen are substantial, its widespread use has been hindered by the high cost of oxygen-separation technologies. In 1992, Air Products and Chemicals, Inc. (APCI), a leading supplier of industrial gases, demonstrated a new approach to oxygen separation in the laboratory. APCI's approach was based on ion-transport membranes (ITMs) that efficiently produce high-purity (greater than 95 percent) oxygen at a high temperature. The company's new approach was limited to basic laboratory trials and had yet to be incorporated into a functional prototype. Therefore, in order to advance the research into this promising technology, APCI submitted a proposal to the Advanced Technology Program (ATP). In their proposal, they highlighted the potentially significant, industry-wide impacts of their proposed technology, as well as the technical risks.
In 1993, ATP awarded APCI cost-shared funding for a three-year project to advance the development of the ITM technology. Although APCI was not able to develop a functional ITM prototype by project end, the ATP-funded project did result in two achievements: the development of ceramic-steel seals and the development of designs and parameters to determine the most efficient method to remove contaminants from oxygen. These accomplishments helped to further APCI's research into oxygen-separation techniques by several years and encouraged the company's management and other agencies to support additional research and development for the ITM technology. The Department of Energy has supported the effort with a funding commitment for three separate three-year research phases between 1998 and 2007 to investigate new oxygen-separation methods.

把气体放到瓶子里,有点燃的火柴放在瓶口,会烧的就是氧气了.
氩气的,你吸一点,吸不死的就是了
氮气的你去问老师吧
化学没学好

冷凝蒸发
