摘要: A method of eluting metal ions from a bed of metal-loaded chelating resin wherein the resin includes a crosslinked styrene-divinylbenzene copolymer matrix with pendent methyleneaminopyridine or phosphonic acid groups and the method includes the step of passing an eluant through the bed to at least partially remove the metal ions from the chelating resin and create a metal-rich eluate, wherein the eluant includes an aqueous solution comprising an amino acid compound having a molecular weight less than 500 Daltons.

摘要: A method for separating natural gas liquids (NGLs) from a hydrocarbon gas mixture containing natural gas liquids and methane, comprising the steps of: i) providing a bed of adsorbent selective for NGLs over methane; ii) passing a hydrocarbon gas mixture containing methane and NGL through the bed of adsorbent to at least partially remove NGLs from the gas mixture to produce: (a) NGL-loaded adsorbent and (b) NGL-depleted hydrocarbon gas mixture; iii) recovering the NGL-depleted hydrocarbon gas mixture; iv) regenerating the NGL-loaded adsorbent by at least partially removing NGLs from the adsorbent; and v) sequentially repeating steps (ii) and (iii) using regenerated adsorbent from step (iv).

摘要: A method for separating N2 from a hydrocarbon gas mixture containing N2 comprising the steps of: i) providing a bed of adsorbent selective for N2; (ii) passing the hydrocarbon gas mixture through the bed of adsorbent to at least partially remove N2 from the gas mixture to produce: (a) N2-loaded adsorbent and (b) N2-depleted hydrocarbon gas mixture; iii) recovering the N2-depleted hydrocarbon gas mixture; iv) regenerating the N2-loaded adsorbent by at least partially removing N2 from the adsorbent; and v) sequentially repeating steps (ii) and (iii) using regenerated adsorbent from step (iv); wherein the adsorbent comprises a pyrolized sulfonated macroporous ion exchange resin.
