摘要： An ultra-high purity monosilane producing process comprises: introducing a monosilane feed gas which also serves as a heat source to the lower stage of a duplex rectification column which is sectioned into an upper stage, a middle stage and a lower stage by means of an intermediate portion reboiler-condenser (RC2) and a lower portion reboiler-condenser (RC1); cooling down the monosilane feed gas by cold in the lower portion reboiler-condenser (RC1) so that the higher boiling point components are separated from the monosilane feed gas; introducing the remaining lower boiling point components to the upper stage by way of the middle stage and the intermediate portion reboiler-condenser (RC2) and cooling down the remaining components by refrigeration in the top portion of the upper stage so that monosilane and a lower boiling point component are separated; and rectifying this monosilane as a reflux liquid, whereby ultra-high purity monosilane is obtained from the bottom portion of the upper stage.

摘要： The present invention relates to a method and apparatus for preparing high purity hydrogen bromide. A starting hydrogen bromide (10) which contains impurities having low boiling points is supplied to an intermediate space (24). While the gas phase of the starting hydrogen bromide is allowed to ascend through an upper rectifying section (23), it is brought into contact with a first reflux solution flowing in the reverse direction. The uncondensed gas stored in an upper space (22) is cooled and partly condensed. The condensed liquid is allowed to flow down through an upper rectifying section (23) as the first reflux solution. The liquid-phase of the starting hydrogen bromide is mixed with the first reflux solution in the intermediate space (24) and serves as a second reflux solution. The liquid stored in a lower space (26) is heated and partly evaporated. The liquid stored in the lower space (26) is supplied outside as high purity hydrogen bromide. The uncondensed gas stored in the upper space (22) is discharged outside.

摘要： A generator produces ultra-high purity nitrogen and ultra-high purity oxygen simultaneously by the liquefaction and rectification of feed air. Feed air is rectified in a first rectification column (4), and nitrogen gas separated to the column top thereof is liquefied, in a nitrogen condenser (8), by oxygen-enriched liquid air separated to the bottom portion of the first rectification column. The oxygen-enriched liquid is fed to the upper portion of a second rectification column (5) having a reboiler (5a) in its column bottom, so that through its rectification in the second rectification column oxygen gas is fed from above a liquid reservoir to the lower portion of the third rectification column (6). Through the rectification of the oxygen gas in the third rectification column, high purity oxygen gas, from which impurities having higher boiling points than that of oxygen have been removed by liquefaction, is fed to the center portion of the fourth rectification column (7) having a condenser (7e) in its top portion and reboiler (7a) in its bottom portion. Through the rectification of the high purity oxygen gas in the fourth rectification column, impurities having lower boiling points than that of oxygen are exhausted from the top portion thereof as non-condensed gas and ultra-high purity liquid oxygen is separated to the column bottom thereof.
