Abstract
Method for concentrating components through a distillation column are disclosed. A process stream is provided containing hydrocarbons, carbon dioxide, and water. The process stream is passed into the distillation column at a bottom portion of the distillation column. The process stream is fractionally distilled in the distillation column, forming an overhead vapor stream, a middle fluid stream, and a bottoms liquid stream. The middle fluid stream is removed from a middle location of the distillation column. The bottoms liquid stream is removed from the distillation column. The overhead vapor stream is removed from the distillation column. The middle fluid stream consists of a first portion of the carbon dioxide and a first portion of the hydrocarbons. The bottoms liquid stream consists of a second portion of the hydrocarbons as a first phase and substantially all the water as a second phase.
