Abstract
A method of vaporizing a multicomponent liquid, such as a hydrogen peroxide and water solution, for injection into a vacuum chamber including the steps of metering successive predetermined increments of the liquid at a predetermined rate onto a heated surface in a vaporization chamber. Upon exposure to the heated surface, each liquid increment is substantially instantaneously vaporized before the next succeeding liquid increment is metered onto the heated surface to produce a multicomponent vapor increment having substantially the same weight percent composition as the multicomponent liquid increment. Each vapor increment is passed into the vacuum chamber.
Claims5
A method of vaporizing a multicomponent liquid comprising:
- metering successive predetermined increments of said multicomponent liquid at a predetermined rate onto a heated surface of a vaporization chamber;
- substantially instantaneously vaporizing each said liquid increment on said heated surface before the succeeding said liquid increment is metered onto said heated surface so that each liquid increment vaporization produces a multicomponent vapor increment having substantially the same weight percent composition as said multicomponent liquid increment;
- and
- passing each said vapor increment into a vacuum chamber.
A method of vaporizing a multicomponent liquid comprising:
- metering a predetermined amount of the multicomponent liquid into a vaporization chamber;
- heating said amount of liquid on a surface of said vaporization chamber to substantially instantaneously raise the least volatile component of said multicomponent liquid to its boiling point to produce a multicomponent vapor having substantially the same percent composition as said amount of said multicomponent liquid;
- passing said multicomponent vapor into a vacuum chamber;
- and
- repeating for a predetermined period of time said metering, heating, and passing steps at a predetermined rate no greater than that required to substantially completely vaporize one said amount of liquid before metering the next said amount of liquid.
