Production of carbon dioxide

Claim 1

THE METHOD OF PRODUCING CARBON DIOXIDE WHICH COMPRISES BURNING A FUEL TO PROVIDE COMBUSTION GASES, THEREAFTER EXPANDING THE COMBUSTION GASES WITHOUT PREVIOUS SUBSTANTIAL LOSS OF PRESSURE AND WITH THE DEVELOPMENT OF EXTERNAL WORK, SCRUBBING THE EXPANDED COMBUSTION GASES PASSING THE SCRUBBED EXPANDED COMBUSTION GASES THROUGH AN ABSORPTION ZONE WHERE THE CARBON DIOXIDE CONTENT OF THE GASES IS SELECTIVELY DISSOLVED IN A SOLVENT THEREFOR, PASSING THE SOLUTION FROM THE ABSORPTION ZONE CONTAINING THE DISSOLVED CARBON DIOXIDE INTO HEAT EXCHANGE RELATIONSHIP WITH THE HOT COMBUSTION GASES AFTER THEY HAVE BEEN EXPANDED AND BEFORE BEING SCRUBBED TO EXPEL CARBON DIOXIDE THEREFROM, COLLECTING THE EXPELLED CARBON DIOXIDE GAS, PASSING THE SOLVENT FROM WHICH THE CARBON DIOXIDE WAS EXPELLED IN HEAT EXCHANGE RELATIONSHIP WITH THE SOLUTION FROM THE ABSORPTION ZONE PASSING TO THE EXPELLING ZONE TO PRELIMINARILY HEAT SUCH SOLUTION BEFORE IT IS BROUGHT INTO HEAT EXCHANGE RELATIONSHIP WITH THE EXPANDED COMBUSTION GASES, COOLING THE SOLVENT FROM WHICH THE CARBON DIOXIDE WAS EXPELLED AFTER IT IS PASSED INTO HEAT EXCHANGE RELATIONSHIP WITH THE SOLUTION FROM THE ABSORPTION ZONE, AND RETURNING THE COOLED SOLVENT TO THE ABSORBING ZONE.

Claim 2

THE METHOD OF PRODUCING CARBON DIOXIDE WHICH COMPRISES BURNING A FUEL TO PROVIDE COMBUSTION GASES, THEREAFTER EXPANDING THE COMBUSTION GASES WITHOUT PREVIOUS SUBSTANTIAL LOSS OF PRESSURE AND WITH THE DEVELOPMENT OF EXTERNAL WORK, SCRUBBING THE EXPANDED COMBUSTION GASES PASSING THE SCRUBBED EXPANDED COMBUSTION GASES THROUGH AN ABSORPTION ZONE WHERE THE CARBON DIOXIDE CONTENT OF THE GASES IS SELECTIVELY DISSOLVED IN A SOLVENT THEREFOR, PASSING THE SOLUTION FROM THE ABSORPTION ZONE CONTAINING THE DISSOLVED CARBON DIOXIDE INTO HEAT EXCHANGE RELATIONSHIP WITH THE HOT COMBUSTION GASES AFTER THEY HAVE BEEN EXPANDED AND BEFORE BEING SCRUBBED TO EXPEL CARBON DIOXIDE THEREFROM, COLLECTING THE EXPELLED CARBON DIOXIDE GAS, PASSING THE SOLVENT FROM WHICH THE CARBON DIOXIDE WAS EXPELLED IN HEAT EXCHANGE RELATIONSHIP WITH THE SOLUTION FROM THE ABSORPTION ZONE PASSING TO THE EXPELLING ZONE TO PRELIMINARILY HEAT SUCH SOLUTION BEFORE IT IS BROUGHT INTO HEAT EXCHANGE RELATIONSHIP WITH THE EXPANDED COMBUSTION GASES, COOLING THE SOLVENT FROM WHICH THE CARBON DIOXIDE WAS EXPELLED AFTER IT IS PASSED INTO HEAT EXCHANGE RELATIONSHIP WITH THE SOLUTION FROM THE ABSORPTION ZONE, AND RETURNING THE COOLED SOLVENT TO THE ABSORBING ZONE.
