Donald F. Othmer's contributions to the technology and art of distillation have covered a span of six decades, and are covered in numerous papers and patents which issued to him. Basic to the many contributions which Dr. Othmer made to distillation technology was his early development of the Othmer Still
This simple-in-principle, but very sophisticated-in-concept method of measuring vapor/liquid equilibrium concentrations permitted rapid development of such equilibrium data, essential to design of distillation systems, with a wide variety of components separations. Early development of the Othmer Still in the form of glassware utilized at atmospheric and sub-atmospheric pressures was advanced by the pressurized Othmer Still (3,8), which permitted extension of vapor/liquid equilibrium data into high-pressure systems for distillation design
Many modifications and applications of the Othmer Still have appeared in the literature over the past fifty years, but the basic principle of achieving true equilibrium by a simple condensate recycle technique has proved the long-term value of this major contribution to distillation technology by Donald F. Othmer. 相似文献

在半导体工业奋力的去迎接明日的封装需求挑战之际,倒装芯片技术无疑将扮演一个重要的角色。为了达到更高的可靠性、更低的成本以及在更小尺寸的封装空间里进行更密集的装配以及更高速度的混合电路的回路,传统的芯片-金线连接方式必须改为倒装芯片的连接技术。倒装芯片封装有以下优点:●更小的尺寸和重量●简化工艺过程并降低构建体系成本●通过缩短信号通道提高电性能●提高散热性能●提高单片电子回路上I/O的数量达到更高的密集度●赋予可使用外围设备或在设计环节里进行排列连接点图案的能力虽然倒装芯片连接在整个连接制造工艺中只占一… 相似文献
