CLAIMS

1 . A method for separating and recovering components from a liquid feedstock, comprising the steps of:

packing a selected sorbent loaded with components from the liquid feedstock, into a first temperature-controlled pressure-resistant column;

sealably engaging the first temperature-controlled pressure-resistant column with (i) a supply of water, and (ii) a cooling equipment for receiving a flow of an eluate from the temperature-controlled pressure-resistant column;

from the supply of water, producing a first flow of pressurized low-polarity (PLP) water at a first selected temperature;

flowing the first flow of PLP water through the temperature-controlled pressure-resistant column thereby producing a first flow of the eluate therefrom, said eluate containing the one or more components;

cooling the first flow of the eluate; and

collecting the cooled first flow of the eluate.

2. A method according claim 1 , additionally comprising a step of commingling the liquid feedstock with the selected sorbent whereby one or more components in the liquid feedstock are bound onto the sorbent, thereby producing a loaded sorbent.

3. A method according claim 1 , additionally comprising:

producing a second flow of PLP water at a second selected temperature; flowing the second flow of PLP water through the first temperature-controlled pressure-resistant column thereby producing a second flow of the eluate therefrom, said eluate containing the one or more components;

cooling the second flow of the eluate; and

collecting the cooled second flow of the eluate.

4. A method according claim 3, additionally comprising:

producing a third flow of PLP water at a third selected temperature;

flowing the third flow of PLP water through the first temperature-controlled pressure-resistant column thereby producing a third flow of the eluate therefrom, said eluate containing the one or more components;

cooling the third flow of the eluate; and

collecting the cooled third flow of the eluate.

5. A method according claim 4, additionally comprising:

producing at least one more flow of PLP water at one more selected temperature;

flowing the at least one more flow of PLP water through the first temperature-controlled pressure-resistant column thereby producing at least one more flow of the eluate therefrom, said eluate containing the one or more components;

cooling the at least one more flow of the eluate; and

collecting the cooled at least one more flow of the eluate.

6. A method according to claim 1 , wherein the loaded sorbent is additionally packed into a second temperature-controlled pressure-resistant column, said second temperature-controlled pressure-resistant column sealably engaged with the first temperature-controlled pressure-resistant column to receive therefrom the flow of the eluate from the first temperature-controlled pressure-resistant column, maintaining the pressurized and heated flow of the eluant through the second temperature-controlled pressure-resistant column, collecting the flow of the eluant from the second temperature-controlled pressure-resistant column, and cooling the collected flow of the eluate.

7. A method according to anyone of claims 1 to 6, additionally comprising a step of further processing the eluate to produce a concentrate therefrom.

8. A method according to anyone of claims 1 to 6, additionally comprising a step of further processing the eluate to produce a dried powder therefrom.

9. A method according to anyone of claims 1 to 6, wherein the sorbent is a sorbent resin.

10. A method according to claim 9, wherein the sorbent resin is selected from the group consisting of poly(styrene-divinylbenzene) resins, poly(divinylbenzene resins, and crosslinked polyamide resins.

1 1 . A method according to anyone of claims 1 to 6, wherein the sorbent is a silica bead sorbent or a molecular sieve or an activated carbon or a bentonite clay or a zirconium oxide or a naturally occurring zeolite or a synthetic zeolite or a diatomaceous earth.

12. A method according to anyone of claims 1 to 6, wherein the sorbent is a silica gel or a bonded C1-C18 silica of a magnesium silicate.
