Abstract

Fremgangsmåte for gjenvinning av en væske fra et par- tikkel f ormig fast stoff som omfatter å blande det faste stoff inneholdende væsken med en partikkelformig polyuretan væske- sorbent, i nærvær eller fravær av vann i en tid og ved en temperatur som er tilstrekkelig til at væsken kan sorberes av den partikkelformige væskesorbent. Deretter blir blandingen av sorbent, fast stoff, og væske fortynnet med vann ved en passende temperatur, og sorbenten inneholdende den sorberte væske adskilt fra vann-faststoffblandingen. Væsken gjenvinnes fra sorbenten ved et sentrifugeringstrinn. Fremgangsmåten kan anvendes på gjenvinning av væsker spilt i grunnen. Den kan også anvendes på gjenvinning av olje fra forekomster som tjæresanden i Athabasca.A process for recovering a liquid from a particulate solid comprising mixing the solid containing the liquid with a particulate polyurethane liquid sorbent, in the presence or absence of water for a time and at a temperature sufficient to the liquid may be sorbed by the particulate liquid sorbent. Then, the sorbent, solid, and liquid mixture is diluted with water at a suitable temperature, and the sorbent containing the sorbed liquid is separated from the water-solid mixture. The liquid is recovered from the sorbent by a centrifugation step. The method can be applied to the recovery of liquids spilled into the ground. It can also be applied to oil recovery from deposits such as the tar sand in Athabasca.
