Abstract
Official abstract text for this publication.
In a process for the separation of a gas rich in carbon dioxide and containing at least one component lighter than carbon dioxide, the feed gas rich in carbon dioxide is cooled in a first heat exchanger, partially condensed and separated to form a gaseous portion and a liquid, sending the liquid portion to the top of a distillation column, removing a liquid stream richer in carbon dioxide than the feed gas from the bottom of the distillation column, removing a gaseous stream less rich in carbon dioxide than the feed gas from the top of the distillation column and warming the gaseous stream in the first heat exchanger, sending the gaseous portion to a shell and tube heat exchanger having tubes in a bath of triple point carbon dioxide, in which it condenses at least partially to form a liquid fraction, sending the liquid fraction to the top of the distillation column, vaporizing a liquid stream from the bottom of the distillation column outside or within the distillation column to form a gas which is subsequently separated in the distillation column, expanding a liquid stream from the bottom of the distillation column, vaporizing at least part of the expanded liquid stream in the shell and tube heat exchanger to form a vapor and warming the vapor formed in the first heat exchanger.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for the separation of a feed gas rich in carbon dioxide and containing at least one component lighter than carbon dioxide, the process comprising the steps of: cooling the feed gas rich in carbon dioxide to a subambient temperature in a first heat exchanger, wherein the feed gas is partially condensed and separated to form a gaseous portion and a liquid portion; sending the liquid portion to the top of a distillation column; removing a li…
