(57) Abstract :
There is disclosed 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 vapour fraction and a concentrated liquid contaminant fraction. The vapour fraction may be
compressed to generate a temperature differential in the reboiler exchanger with the vapour fraction being passed into contact with a
reboiler exchanger to provide a stream of condensed vapour 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 vapour in the stream. The apparatus includes a
unique configuration of a vapour compressor, heated separator in combination with a forced circulation circuit to generate the
decontamination result.
