Separating carbon dioxide from natural gas liquids

摘要

Embodiments described herein provide a method and systems for separating carbon dioxide from heavy hydrocarbons. The method includes cooling a first liquid stream including carbon dioxide and heavy hydrocarbons within an oscillatory crystallization unit to generate carbon dioxide solids and a second liquid stream including the heavy hydrocarbons. The method also includes separating the carbon dioxide solids from the second liquid stream via a solid-liquid separation system.
