A process for recovering processing liquids such as gas-treating liquids wherein a feed mixture containing the processing liquid, water, and optionally additional components that are more volatile than the processing liquid and components that are less volatile than the processing liquid, is initially heated in a first heating zone to a temperature sufficient to volatilize at least some of the water and a portion of the processing liquid without decomposing the processing liquid to produce a vapor stream containing volatilized water and processing liquid and a residuum containing the bulk of the processing liquid and less volatile component, the vapor stream being separated from the residuum and treated to produce recycle streams of water, purified processing liquid, and low and high boiling liquid fractions recovered from the purified processing liquid.

Process for recovering processing liquids

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.
