Abstract:
A method to condense and recover carbon dioxide. A first step involve providing at more than one heat exchanger, with each heat exchanger having a first flow path for passage of a first fluid and a second flow path for passage of a second fluid. A second step involves passing a stream of very cold natural gas sequentially along the first flow path of each heat exchanger until it is heated for distribution and concurrently passing a gaseous stream rich in carbon dioxide sequentially along the second flow path of each heat exchanger, allowing a gaseous portion of the gaseous stream rich in carbon dioxide to pass to a next sequential heat exchanger and capturing in a collection vessel the condensed carbon dioxide. This processes results in a cryogenic heat exchange in which natural gas at Metering and Pressure Reduction Stations is first cooled by reducing its pressure through a gas expander or a pressure reducing valve and then heated in a series of stages and the gaseous stream rich in carbon dioxide stream is separated in a series of stages through sequential cryogenic carbon dioxide separation and recovery.
