| titleOfInvention | Process for separating solids from valuable or harmful liquids by vaporisation |
| abstract | Disclosed herein is a method of extracting solids, which are dissolved or undissolved, from a mixture of water and a process liquid, comprising the steps of: a) placing an oil or oil-like recycle source liquid that is less dense than water, preferably mono-ethylene glycol, and is comprised of components that are substantially non-miscible with and less volatile than water and less volatile than the process liquid, into a separation vessel; b) introducing a feed stream comprising a mixture of water, the process liquid and the solids to be extracted, into a mixing zone in proximity to or within the separation vessel; c) rapidly boiling or flashing the feed stream upon mixing the feed stream with a recycle fluid in the mixing zone to produce a vapour in proximity to or within the separation vessel; d) separating the vapour from unvaporised components of a mixture of the feed stream and the recycle fluid; e) collecting the unvaporised components in a substantially liquid pool in a lower portion of the separation vessel; f) drawing the recycle fluid from the substantially liquid pool at a rate that is more than ten times the feed stream flow rate; g) pumping the recycle fluid through a heat exchanger; h) supplying sufficient heat to the recycle fluid in the heat exchanger such that the amount of heat added to the recycle fluid is sufficient to vaporise volatile components of the feed stream when the recycle fluid and the feed stream are mixed in the mixing zone; i) allowing at least a portion of the solids in the substantially liquid pool and at least a portion of any liquid bound thereto to move into a stripping zone and come into contact with water contained therein; j) allowing at least a portion of the solids that has moved into the stripping zone to move through at least a portion of the water in the stripping zone; k) wherein the passage of the portion of solids through the portion of the water displaces at least a portion of any other liquid bound to the portion of the solids; and I) removing from the stripping zone a waste aqueous stream comprising at least a portion of the solids that have entered the stripping zone. |
