Abstract:
Embodiments described herein provide methods and systems for separating a mixed ethane and CO 2 . A method described includes generating a liquid stream including ethane and CO 2 . The liquid stream is flashed to form an ethane vapor stream and solid CO 2 . The solid CO 2  is accumulated in an accumulation vessel and the gas is removed from the top of the accumulation vessel.

Claim (Index 11):
A system for separating a mixed stream of CO 2  and ethane, comprising:\n a purification system configured to remove contaminants from the mixed stream and generate a liquid stream comprising an azeotropic mixture of ethane and CO 2 ; a flash valve configured to isoenthalpically flash the mixed liquid stream forming solid CO 2  and a vapor stream enhanced in ethane; and an accumulation vessel configured to capture the solid CO 2 ; a compressor and a chiller configured to recondense the vapor stream forming a condensed gas; a fractionator configured to remove a contaminated ethane stream, comprising ethane, methane, and CO 2 , from the condensed gas; a flash vessel configured to separate methane from the contaminated ethane stream, thereby forming a remainder stream that comprises ethane and CO 2 , wherein the remainder stream is combined with the liquid stream; wherein the accumulation vessel has an outlet valve and a heater, the heater configured to\n warm the solid CO 2  in the accumulation vessel and drive off trapped hydrocarbon therein when the outlet valve is open, and \n melt the solid CO 2  in the accumulation vessel when the outlet valve is closed, thereby forming a liquid CO 2  product stream.
