Abstract
Official abstract text for this publication.
A method of simultaneously liquefying CO2 and cooling natural gas, including providing a compressed CO2 loop, comprising a pressurized cooling stream, wherein a first compressed cooling stream and a second compressed cooling stream are produced by a CO2 compressor. Providing at least a portion of the first compressed cooling stream to a CO2 liquefaction system, wherein the first compressed cooling stream provides at least a portion of the refrigeration required by the CO2 liquefaction system. Providing at least a portion of the second compressed cooling stream to the pre-cooling system of a natural gas liquefaction system, wherein the second compressed cooling stream provides at least a portion of the refrigeration required by the natural gas pre-cooling.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of simultaneously liquefying CO2 and cooling natural gas, comprising: providing a compressed CO2 loop, comprising a pressurized stream, wherein a first compressed stream and a second compressed stream are produced by a CO2 compressor, providing at least a portion of the first compressed stream to a CO2 liquefaction system, wherein the first compressed stream provides at least a portion of the refrigeration required by the CO2 liquefaction system, providing at least a portion of the second compressed stream to the pre-cooling system of a natural gas liquefaction system, wherein the second compressed stream provides at least a portion of the refrigeration required by the natural gas pre-cooling. 2 . The method of claim 1 , wherein the lowest pressure within the CO2 loop is greater than the triple point pressure of CO2. 3 . The method of claim 1 , wherein the CO2 liquefaction system comprises at least one recycle stream that is introduced into the CO2 compressed CO2 loop. 4 . The method of claim 1 , wherein the first compressed cooling stream and the second compressed cooling stream are at the same pressure. 5 . The method of claim 1 , wherein the first compressed cooling stream and the second compressed cooling stream are at different pressures. 6 . A method of simultaneously producing a pressurized CO2 stream and cooling natural gas, comprising: providing a CO2 compressor system, comprising at least a first compressed stream and a second compressed stream, wherein the first compressed stream and the second compressed stream are produced by a CO2 compressor, providing at least a portion of the first compressed stream to a downstream user, providing at least a portion of the second compressed stream to the pre-cooling system of a natural gas liquefaction system, wherein the second compressed stream provides at least a portion of the refrigeration required by the natural gas pre-cooling. 7 . The method of claim 6 , wherein the lowest pressure within the CO2 loop is greater than the triple point pressure of CO2. 8 . The method of claim 6 , wherein the downstream user is an enhanced oil recovery system. 9 . The method of claim 6 , wherein the downstream user is a CO2 sequestration system.
