초록 ▼

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).

1. A method for separating methane or ethane from a hydrocarbon gas mixture comprising methane or ethane, or a combination of methane and ethane, along with C3 and heavier paraffins, wherein the method comprises the steps of: i) providing a bed of a macroporous alkylene-bridged adsorbent selective for C3 and heavier paraffins over methane and ethane;ii) passing a hydrocarbon gas mixture through the bed of adsorbent to at least partially remove C3 and heavier paraffins from the gas mixture to produce: (a) C3 and heavier paraffins-loaded adsorbent and (b) C3 and heavier paraffins-depleted hydrocarbon gas mixture;iii) recovering the C3 and heavier paraffins-depleted hydrocarbon gas mixture;iv) regenerating the C3 and heavier-loaded adsorbent by at least partially removing C3 and heavier paraffins from the adsorbent; andv) sequentially repeating steps (ii) and (iii) using regenerated adsorbent from step (iv). 2. A method for separating methane from a hydrocarbon gas mixture comprising methane and natural gas liquids (NGLs) that comprise ethane and heavier paraffins, wherein the method comprises the steps of: i) providing a bed of a macroporous alkylene-bridged adsorbent selective for NGLs over methane;ii) passing a hydrocarbon gas mixture through the bed of adsorbent to at least partially remove NGLs from the gas mixture to produce: (a) NGLs-loaded adsorbent and (b) NGLs-depleted hydrocarbon gas mixture;iii) recovering the NGLs-depleted hydrocarbon gas mixture;iv) regenerating the NGLs-loaded adsorbent by at least partially removing NGLs from the adsorbent; andv) sequentially repeating steps (ii) and (iii) using regenerated adsorbent from step (iv). 3. The method of claim 2 wherein step (i) occurs in an adsorption chamber, and step (iv) occurs in a desorption chamber, and wherein NGL-loaded adsorbent is continuously transferred from the adsorption chamber to the desorption chamber, and regenerated adsorbent is continuously transferred from the desorption chamber to the adsorption chamber. 4. The method of claim 3 wherein the adsorbent located in the adsorption chamber forms a packed moving bed. 5. The method of claim 2 wherein the step of regenerating the NGL-loaded adsorbent comprises irradiating the adsorbent with microwaves. 6. The method of claim 1 wherein the adsorbent comprises a functionalized macroporous alkylene-bridged adsorbent. 7. The method of claim 6 wherein the macroporous alkylene-bridged adsorbent comprises an amine or a sulfur containing functional group. 8. The method of claim 2 wherein the step of regeneration comprises exposing the adsorbent to lower pressure. 9. The method of claim 2 wherein the adsorbent comprises a functionalized macroporous alkylene-bridged adsorbent.
