Abstract
A method and apparatus for removing a contaminant from a fluid feed stream containing the contaminant. The method includes the steps of providing a feed stream ( ) and heating it in a first step ( ) to at least partially remove some of the contaminants and recover energy from a concentrate and distillate generated. Further heating the feed stream in a second heating step ( ) in a heated separator generates a saturated vapor fraction ( ) and a concentrated liquid contaminant fraction. The vapor fraction ( ) may be compressed ( ) to generate a temperature differential in the reboiler exchanger ( ) with the vapor fraction being passed into contact with a reboiler exchanger ( ) to provide a stream of condensed vapor from the reboiler. The stream may be circulated through the reboiler exchanger ( ) and the heated separator to maintain from about 1% to about 50% by mass vapor in the stream. The apparatus includes a unique configuration of a vapor compressor, heated separator in combination with a forced circulation ( ) circuit to generate the decontamination result.
