Recompression cycle for recovery of natural gas liquids |
摘要 |
<p>Natural gas liquids (NGLs) are recovered by cooling and partial condensation of a purified natural gas feed wherein a portion of the necessary feed cooling and condensation duty is provided by expansion and vaporization of condensed feed liquid after methane stripping, thereby yielding a vaporized NGL product. Additional refrigeration for feed cooling is provided by vaporizing methane-stripped liquid, which in turn provides vapor boilup for the stripping step. Recompression and cooling of the vaporized NGL product can be utilized if a liquid product is required.</p> |
