Abstract
A method and apparatus for separating water from a condensate mixture having two or more components drained from a compressed gas system is disclosed. The apparatus has a boiler with an inlet for receiving the condensate mixture and an outlet through which water vapor is removed. The boiler is maintained at sufficient negative pressure to lower the boiling point of the water in the condensate mixture and to enable the water in the boiler to boil at a lower temperature than if the negative pressure were not present. Heat is provided to the boiler to raise the temperature of the condensate mixture to equal or exceed that of the boiling point of the water in the negative pressure environment, but below the boiling point of the remaining components in the condensate mixture.
