Abstract

Contemplated plants include a NGL recovery portion and a LNG liquefaction portion, wherein the NGL recovery portion provides a low-temperature and high-pressure overhead product directly to the LNG liquefaction portion. Feed gas cooling and condensation are most preferably performed using refrigeration cycles that employ refrigerants other than the demethanizer/absorber overhead product. Thus, cold demethanizer/absorber overhead product is compressed with the turbo-expansion and delivered to a liquefaction portion at significantly lower temperature and higher pressure without net compression energy expenditure.

Claims (20)

1. A gas processing plant, comprising;

a separator that is configured to receive a partially expanded vapor portion of a natural gas feed stream, and that is further configured to produce a cold overhead product stream;

an expander operationally coupled to drive a compressor; wherein the expander is configured to produce the partially expanded vapor portion and wherein the compressor is configured to produce a compressed cryogenic overhead product stream from the cold overhead product stream;

wherein the separator and the compressor are fluidly coupled to each other such that the compressed cryogenic overhead product stream has a pressure of at least psig at a temperature of no warmer than -50 °F; and a natural gas liquefaction unit that is fluidly coupled to the compressor to receive the cryogenic overhead product stream at about the pressure and at about the temperature.
2. The plant of claim 1 wherein the separator is configured to receive another expanded vapor portion of the natural gas feed stream at a separate location.
3. The plant of claim 1 wherein the separator is configured to operate as a demethanizer.
4. The plant of claim 3 further comprising a deethanizer that is configured to produce a C3+ product and a C2 product.
5. The plant of claim 4 further comprising a conduit that provides at least part of the C2 product to the cold overhead product stream.
6. The plant of claim 1 wherein the separator is configured to operate as a refluxed absorber.
7. The plant of claim 6 wherein the demethanizer is configured to provide a reflux stream to the absorber.
8. The plant of claim 6 wherein the demethanizer is configured to operate at a lower pressure than the absorber.
9. The plant of claim 6 further comprising at least one of a conduit that provides a cooled absorber bottom product the absorber for C2 recovery and a conduit that provides a heated absorber bottom product the absorber for C2 rejection.
10. A method of producing a liquefied natural gas, comprising:

producing a cold overhead product stream in a separator and compressing the product stream in a compressor without prior substantial heating of the cold overhead product stream;

wherein the compressor is driven by an expander that expands a vapor portion of a natural gas feed, and wherein the expanded vapor portion is fed into the separator;
and liquefying the cold compressed product stream in a liquefaction unit.
11. The method of claim 10 wherein the separator is operated as a demethanizer that further receives another portion of a natural gas feed.
12. The method of claim 10 further comprising a deethanizer that receives a bottom product of the separator and that optionally provides a C2 product to the cold overhead product stream.
13. The method of claim 10 wherein the separator is operated as a refluxed absorber.
14. The method of claim 11 wherein a demethanizer provides a reflux stream to the absorber, wherein the absorber provides a bottom product to the demethanizer, and wherein the demethanizer is operated at a lower pressure than the absorber.
15. The method of claim 14 wherein the absorber bottom product is heated for rejection prior to entering the demethanizer or cooled for C2 recovery prior to entering the demethanizer.

17. The method of claim 10 wherein the cold compressed product stream has a pressure of at least 700 psig and a temperature of no warmer than -50 °F.
18. A method of producing LNG comprising:

separating in a separator a cold overhead product from a natural gas containing feed gas;

wherein the cold compressed overhead product is formed at neutral or negative net compression energy requirement.
19. The method of claim 17 wherein the step of separating is performed in an absorber or a demethanizer.
