Abstract
Official abstract text for this publication.
A method and device for the cryogenic separation of a methane-rich flow is provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for the cryogenic separation of a methane-rich feed flow also comprising carbon dioxide and a second impurity selected from the group consisting of nitrogen, oxygen, and a combination thereof, said method comprising the steps of: i) sending the methane-rich feed flow to an adsorption purification unit to produce a carbon dioxide-lean flow having less carbon dioxide relative to the methane-rich feed flow; ii) cooling at least part of the carbon dio…
