PURIFICATION METHODS USING SORBENTS AND PRESSURIZED LOW-POLARITY WATER EXTRACTION

摘要

A method for separating, purifying, and recoveringcomponents from a liquid feedstock. The method stepsinclude (i) commingling the liquid feedstock with a sorbentwhereby one or more components in the liquid feedstock are boundonto the sorbent, thereby producing a loaded sorbent; (ii) packingthe loaded sorbent into a first temperature-controlled pressure-resistantcolumn; (iii) sealably engaging the first temperature-controlledpressure-resistant column with a supply of water, and coolingequipment for receiving a flow of an eluate from the temperature-controlledpressure- resistant column; (iv) from the supply ofwater, producing a first flow of PLP water at a first selectedtemperature; (v) flowing the first flow of PLP water through thetemperature-controlled pressure-resistant column thereby producinga first flow of the eluate therefrom, said eluate containing the oneor more components; (vi) cooling the first flow of the eluate; and(vii) collecting the cooled first flow of the eluate.
