    摘要： A method of recovering carbon dioxide from a synthesis gas stream generated within a synthesis gas facility. After the synthesis gas stream is passed through at least one process heat exchanger of the steam generation system located downstream of the water-gas shift reactor, the temperature of the synthesis gas stream is increased while simultaneously adding steam to the synthesis gas stream. Thereafter, the synthesis gas stream is added to an absorption system having an absorption zone utilizing a solvent to absorb the carbon dioxide and a regeneration zone to disengage the carbon dioxide from the solvent and thereby regenerate the solvent. Heat is transferred from the synthesis gas stream to the regeneration zone to promote disengagement of the carbon dioxide from the steam and such that between about 40 percent and about 90 percent of the carbon dioxide originally present in the synthesis gas stream is recovered.

    摘要： A method of recovering carbon dioxide from a synthesis gas stream generated within a facility having a synthesis gas reactor, a water-gas shift reactor and a steam generation system for generating steam for the synthesis gas reactor and for export. After the synthesis gas stream is passed through at least one process heat exchanger of the steam generation system located downstream of the water-gas shift reactor, the temperature of the synthesis gas stream is increased while simultaneously adding steam to the synthesis gas stream. Thereafter, the synthesis gas stream is added to an absorption system having an absorption zone utilizing a solvent to absorb the carbon dioxide and a regeneration zone to disengage the carbon dioxide from the solvent and thereby regenerate the solvent. Heat is transferred from the synthesis gas stream to the regeneration zone to promote disengagement of the carbon dioxide from the steam and such that between about 40 percent and about 90 percent of the carbon dioxide originally present in the synthesis gas stream is recovered. The temperature of the synthesis gas stream can be increased and steam can be added thereto by mixing superheated steam with the synthesis gas stream. Alternatively, a synthesis gas stream can be introduced into a saturator utilizing a water stream that undergoes indirect heat exchange with a low pressure steam stream.

    摘要： The present invention provides a method of increasing the efficiency of exothermic CO2 capture processes. The method relates to withdrawing heat generated during the exothermic capture of CO2 with various sorbents via heat exchange with a working fluid. The working fluid is provided at a temperature and pressure such that it is in the liquid state, and has a vaporization temperature in a range such that the heat arising from the reaction of the CO2 and the sorbent causes a phase change from liquid to vapor state in whole or in part and transfers heat from to the working fluid. The resulting heated working fluid may subsequently be used to generate power.
