摘要： A process for the economical recovery of carbon dioxide from a gas stream containing less than 85% carbon dioxide, by cooling the contaminating gas to remove water vapor, compressing the cooled gas to an elevated temperature and pressure, and drying the gas to a dewpoint of not more than about -85.degree. F.; condensing and removing the carbon dioxide from the dried compressed gas; and heating the remaining noncondensed gas mixture and expanding it to produce and recover kinetic energy and a cooled gas mixture.

摘要： There is provided a process for liquefying a flow of relatively impure carbon dioxide gas in conjunction with providing a carbonation flow of relatively pure carbon dioxide gas, which includes the steps of condensing a source flow of carbon dioxide gas, containing contaminating gas having a substantially lower condensation temperature, by passing the source flow in heat exchange relation with a coolant flow of relatively pure carbon dioxide liquid while flashing the coolant flow at a selectively reduced pressure to maintain said heat exchange relation; then separating contaminating gases from the condensed source flow; and then merging the condensed source flow into said liquid coolant flow. Apparatus for practicing the process is also provided.

摘要： There is provided a method for liquefying carbon dioxide gas containing contaminating gas having a lower condensation temperature than that of carbon dioxide, comprising introducing a source flow of carbon dioxide gas containing contaminating gas into a chamber of liquid carbon dioxide at a temperature and pressure to selectively condense carbon dioxide from the source flow, while permitting the contaminating gas to escape from the liquid carbon dioxide; and passing a coolant flow of liquid carbon dioxide in heat exchange relation with the chamber while flashing the coolant flow to maintain the heat exchange relation. Advantageously, the condensed source flow is merged into the liquid coolant flow, and the flashed coolant flow is regulated to maintain a selectively reduced pressure so as to control the temperature of flashing. Contaminating gas collected in the hot path of the exchanger is selectively released to control pressure therein. Apparatus for practicing the method is also disclosed.

摘要： A carbon dioxide liquification system. Gaseous carbon dioxide containing at least one contaminating gas having a lower temperature of liquification than the gaseous carbon dioxide, such as oxygen or nitrogen, is bubbled through liquid carbon dioxide such that the gaseous substances undergo heat exchange with the liquid carbon dioxide. Sufficient heat exchange takes place so as to liquify the gaseous carbon dioxide but not sufficient to substantially liquify the contaminating gas. The contaminating gas is permitted to escape from the liquid carbon dioxide. Apparatus for practicing the present invention is also disclosed.
